Measuring problem-solving performance in AI

We can evaluate an algorithm’s performance in four ways in Artificial intelligence

  • Completeness
  • Time complexity
  • Space complexity

Time and space complexity are always considered with respect to some measure of the problem difficulty. In theoretical computer science, the typical measure is the size of the state space graph, |V | + |E| , where V is the set of vertices (nodes) of the graph and E is the set of edges (links). This is appropriate when the graph is an explicit data structure that is input to the search program. (The map of Romania is an example of this.) In AI , the graph is often represented implicitly by the initial state , actions , and transition model and is frequently infinite

Chapter 3 Solving Problems by Searching 

When the correct action to take is not immediately obvious, an agent may need to plan ahead : to consider a sequence of actions that form a path to a goal state. Such an agent is called a problem-solving agent , and the computational process it undertakes is called search .

Problem-solving agents use atomic representations, that is, states of the world are considered as wholes, with no internal structure visible to the problem-solving algorithms. Agents that use factored or structured representations of states are called planning agents .

We distinguish between informed algorithms, in which the agent can estimate how far it is from the goal, and uninformed algorithms, where no such estimate is available.

3.1 Problem-Solving Agents 

If the agent has no additional information—that is, if the environment is unknown —then the agent can do no better than to execute one of the actions at random. For now, we assume that our agents always have access to information about the world. With that information, the agent can follow this four-phase problem-solving process:

GOAL FORMULATION : Goals organize behavior by limiting the objectives and hence the actions to be considered.

PROBLEM FORMULATION : The agent devises a description of the states and actions necessary to reach the goal—an abstract model of the relevant part of the world.

SEARCH : Before taking any action in the real world, the agent simulates sequences of actions in its model, searching until it finds a sequence of actions that reaches the goal. Such a sequence is called a solution .

EXECUTION : The agent can now execute the actions in the solution, one at a time.

It is an important property that in a fully observable, deterministic, known environment, the solution to any problem is a fixed sequence of actions . The open-loop system means that ignoring the percepts breaks the loop between agent and environment. If there is a chance that the model is incorrect, or the environment is nondeterministic, then the agent would be safer using a closed-loop approach that monitors the percepts.

In partially observable or nondeterministic environments, a solution would be a branching strategy that recommends different future actions depending on what percepts arrive.

3.1.1 Search problems and solutions 

A search problem can be defined formally as follows:

A set of possible states that the environment can be in. We call this the state space .

The initial state that the agent starts in.

A set of one or more goal states . We can account for all three of these possibilities by specifying an \(Is\-Goal\) method for a problem.

The actions available to the agent. Given a state \(s\) , \(Actions(s)\) returns a finite set of actions that can be executed in \(s\) . We say that each of these actions is applicable in \(s\) .

A transition model , which describes what each action does. \(Result(s,a)\) returns the state that results from doing action \(a\) in state \(s\) .

An action cost function , denote by \(Action\-Cost(s,a,s\pr)\) when we are programming or \(c(s,a,s\pr)\) when we are doing math, that gives the numeric cost of applying action \(a\) in state \(s\) to reach state \(s\pr\) .

A sequence of actions forms a path , and a solution is a path from the initial state to a goal state. We assume that action costs are additive; that is, the total cost of a path is the sum of the individual action costs. An optimal solution has the lowest path cost among all solutions.

The state space can be represented as a graph in which the vertices are states and the directed edges between them are actions.

3.1.2 Formulating problems 

The process of removing detail from a representation is called abstraction . The abstraction is valid if we can elaborate any abstract solution into a solution in the more detailed world. The abstraction is useful if carrying out each of the actions in the solution is easier than the original problem.

3.2 Example Problems 

A standardized problem is intended to illustrate or exercise various problem-solving methods. It can be given a concise, exact description and hence is suitable as a benchmark for researchers to compare the performance of algorithms. A real-world problem , such as robot navigation, is one whose solutions people actually use, and whose formulation is idiosyncratic, not standardized, because, for example, each robot has different sensors that produce different data.

3.2.1 Standardized problems 

A grid world problem is a two-dimensional rectangular array of square cells in which agents can move from cell to cell.

Vacuum world

Sokoban puzzle

Sliding-tile puzzle

3.2.2 Real-world problems 

Route-finding problem

Touring problems

Trveling salesperson problem (TSP)

VLSI layout problem

Robot navigation

Automatic assembly sequencing

3.3 Search Algorithms 

A search algorithm takes a search problem as input and returns a solution, or an indication of failure. We consider algorithms that superimpose a search tree over the state-space graph, forming various paths from the initial state, trying to find a path that reaches a goal state. Each node in the search tree corresponds to a state in the state space and the edges in the search tree correspond to actions. The root of the tree corresponds to the initial state of the problem.

The state space describes the (possibly infinite) set of states in the world, and the actions that allow transitions from one state to another. The search tree describes paths between these states, reaching towards the goal. The search tree may have multiple paths to (and thus multiple nodes for) any given state, but each node in the tree has a unique path back to the root (as in all trees).

The frontier separates two regions of the state-space graph: an interior region where every state has been expanded, and an exterior region of states that have not yet been reached.

3.3.1 Best-first search 

In best-first search we choose a node, \(n\) , with minimum value of some evaluation function , \(f(n)\) .

../_images/Fig3.7.png

3.3.2 Search data structures 

A node in the tree is represented by a data structure with four components

\(node.State\) : the state to which the node corresponds;

\(node.Parent\) : the node in the tree that generated this node;

\(node.Action\) : the action that was applied to the parent’s state to generate this node;

\(node.Path\-Cost\) : the total cost of the path from the initial state to this node. In mathematical formulas, we use \(g(node)\) as a synonym for \(Path\-Cost\) .

Following the \(PARENT\) pointers back from a node allows us to recover the states and actions along the path to that node. Doing this from a goal node gives us the solution.

We need a data structure to store the frontier . The appropriate choice is a queue of some kind, because the operations on a frontier are:

\(Is\-Empty(frontier)\) returns true only if there are no nodes in the frontier.

\(Pop(frontier)\) removes the top node from the frontier and returns it.

\(Top(frontier)\) returns (but does not remove) the top node of the frontier.

\(Add(node, frontier)\) inserts node into its proper place in the queue.

Three kinds of queues are used in search algorithms:

A priority queue first pops the node with the minimum cost according to some evaluation function, \(f\) . It is used in best-first search.

A FIFO queue or first-in-first-out queue first pops the node that was added to the queue first; we shall see it is used in breadth-first search.

A LIFO queue or last-in-first-out queue (also known as a stack ) pops first the most recently added node; we shall see it is used in depth-first search.

3.3.3 Redundant paths 

A cycle is a special case of a redundant path .

As the saying goes, algorithms that cannot remember the past are doomed to repeat it . There are three approaches to this issue.

First, we can remember all previously reached states (as best-first search does), allowing us to detect all redundant paths, and keep only the best path to each state.

Second, we can not worry about repeating the past. We call a search algorithm a graph search if it checks for redundant paths and a tree-like search if it does not check.

Third, we can compromise and check for cycles, but not for redundant paths in general.

3.3.4 Measuring problem-solving performance 

COMPLETENESS : Is the algorithm guaranteed to find a solution when there is one, and to correctly report failure when there is not?

COST OPTIMALITY : Does it find a solution with the lowest path cost of all solutions?

TIME COMPLEXITY : How long does it take to find a solution?

SPACE COMPLEXITY : How much memory is needed to perform the search?

To be complete, a search algorithm must be systematic in the way it explores an infinite state space, making sure it can eventually reach any state that is connected to the initial state.

In theoretical computer science, the typical measure of time and space complexity is the size of the state-space graph, \(|V|+|E|\) , where \(|V|\) is the number of vertices (state nodes) of the graph and \(|E|\) is the number of edges (distinct state/action pairs). For an implicit state space, complexity can be measured in terms of \(d\) , the depth or number of actions in an optimal solution; \(m\) , the maximum number of actions in any path; and \(b\) , the branching factor or number of successors of a node that need to be considered.

3.4 Uninformed Search Strategies 

3.4.1 breadth-first search .

When all actions have the same cost, an appropriate strategy is breadth-first search , in which the root node is expanded first, then all the successors of the root node are expanded next, then their successors, and so on.

../_images/Fig3.9.png

Breadth-first search always finds a solution with a minimal number of actions, because when it is generating nodes at depth \(d\) , it has already generated all the nodes at depth \(d-1\) , so if one of them were a solution, it would have been found.

All the nodes remain in memory, so both time and space complexity are \(O(b^d)\) . The memory requirements are a bigger problem for breadth-first search than the execution time . In general, exponential-complexity search problems cannot be solved by uninformed search for any but the smallest instances .

3.4.2 Dijkstra’s algorithm or uniform-cost search 

When actions have different costs, an obvious choice is to use best-first search where the evaluation function is the cost of the path from the root to the current node. This is called Dijkstra’s algorithm by the theoretical computer science community, and uniform-cost search by the AI community.

The complexity of uniform-cost search is characterized in terms of \(C^*\) , the cost of the optimal solution, and \(\epsilon\) , a lower bound on the cost of each action, with \(\epsilon>0\) . Then the algorithm’s worst-case time and space complexity is \(O(b^{1+\lfloor C^*/\epsilon\rfloor})\) , which can be much greater than \(b^d\) .

When all action costs are equal, \(b^{1+\lfloor C^*/\epsilon\rfloor}\) is just \(b^{d+1}\) , and uniform-cost search is similar to breadth-first search.

3.4.3 Depth-first search and the problem of memory 

Depth-first search always expands the deepest node in the frontier first. It could be implemented as a call to \(Best\-First\-Search\) where the evaluation function \(f\) is the negative of the depth.

For problems where a tree-like search is feasible, depth-first search has much smaller needs for memory. A depth-first tree-like search takes time proportional to the number of states, and has memory complexity of only \(O(bm)\) , where \(b\) is the branching factor and \(m\) is the maximum depth of the tree.

A variant of depth-first search called backtracking search uses even less memory.

3.4.4 Depth-limited and iterative deepening search 

To keep depth-first search from wandering down an infinite path, we can use depth-limited search , a version of depth-first search in which we supply a depth limit, \(l\) , and treat all nodes at depth \(l\) as if they had no successors. The time complexity is \(O(b^l)\) and the space complexity is \(O(bl)\)

../_images/Fig3.12.png

Iterative deepening search solves the problem of picking a good value for \(l\) by trying all values: first 0, then 1, then 2, and so on—until either a solution is found, or the depth- limited search returns the failure value rather than the cutoff value.

Its memory requirements are modest: \(O(bd)\) when there is a solution, or \(O(bm)\) on finite state spaces with no solution. The time complexity is \(O(bd)\) when there is a solution, or \(O(bm)\) when there is none.

In general, iterative deepening is the preferred uninformed search method when the search state space is larger than can fit in memory and the depth of the solution is not known .

3.4.5 Bidirectional search 

An alternative approach called bidirectional search simultaneously searches forward from the initial state and backwards from the goal state(s), hoping that the two searches will meet.

../_images/Fig3.14.png

3.4.6 Comparing uninformed search algorithms 

../_images/Fig3.15.png

3.5 Informed (Heuristic) Search Strategies 

An informed search strategy uses domain–specific hints about the location of goals to find colutions more efficiently than an uninformed strategy. The hints come in the form of a heuristic function , denoted \(h(n)\) :

\(h(n)\) = estimated cost of the cheapest path from the state at node \(n\) to a goal state.

3.5.1 Greedy best-first search 

Greedy best-first search is a form of best-first search that expands first the node with the lowest \(h(n)\) value—the node that appears to be closest to the goal—on the grounds that this is likely to lead to a solution quickly. So the evaluation function \(f(n)=h(n)\) .

The right approach can help you spot where resources are being wasted — and how the system can be improved.

Understanding how to evaluate and manage algorithmic performance could be the difference between success and failure. This article outlines a six-step approach for defining what to measure and monitor. Central to this approach is to work out where the waste is by measuring failure states.

How Does Artificial Intelligence Solve Problems? An In-Depth Look at Problem Solving in AI

What is problem solving in artificial intelligence? It is a complex process of finding solutions to challenging problems using computational algorithms and techniques. Artificial intelligence, or AI, refers to the development of intelligent systems that can perform tasks typically requiring human intelligence.

Solving problems in AI involves the use of various algorithms and models that are designed to mimic human cognitive processes. These algorithms analyze and interpret data, generate possible solutions, and evaluate the best course of action. Through machine learning and deep learning, AI systems can continuously improve their problem-solving abilities.

Artificial intelligence problem solving is not limited to a specific domain or industry. It can be applied in various fields such as healthcare, finance, manufacturing, and transportation. AI-powered systems can analyze vast amounts of data, identify patterns, and make predictions to solve complex problems efficiently.

Understanding and developing problem-solving capabilities in artificial intelligence is crucial for the advancement of AI technologies. By improving problem-solving algorithms and models, researchers and developers can create more efficient and intelligent AI systems that can address real-world challenges and contribute to technological progress.

What is Artificial Intelligence?

Artificial intelligence (AI) can be defined as the simulation of human intelligence in machines that are programmed to think and learn like humans. It is a branch of computer science that deals with the creation and development of intelligent machines that can perform tasks that normally require human intelligence.

AI is achieved through the use of algorithms and data that allow machines to learn from and adapt to new information. These machines can then use their knowledge and reasoning abilities to solve problems, make decisions, and even perform tasks that were previously thought to require human intelligence.

Types of Artificial Intelligence

There are two main types of AI: narrow or weak AI and general or strong AI.

Narrow AI refers to AI systems that are designed to perform specific tasks, such as language translation, image recognition, or playing chess. These systems are trained to excel in their specific tasks but lack the ability to generalize their knowledge to other domains.

General AI, on the other hand, refers to AI systems that have the ability to understand, learn, and apply knowledge across a wide range of tasks and domains. These systems are capable of reasoning, problem-solving, and adapting to new situations in a way that is similar to human intelligence.

The Role of Problem Solving in Artificial Intelligence

Problem solving is a critical component of artificial intelligence. It involves the ability of AI systems to identify problems, analyze information, and develop solutions to those problems. AI algorithms are designed to imitate human problem-solving techniques, such as searching for solutions, evaluating options, and making decisions based on available information.

AI systems use various problem-solving techniques, including algorithms such as search algorithms, heuristic algorithms, and optimization algorithms, to find the best solution to a given problem. These techniques allow AI systems to solve complex problems efficiently and effectively.

In conclusion, artificial intelligence is the field of study that focuses on creating intelligent machines that can perform tasks that normally require human intelligence. Problem-solving is a fundamental aspect of AI and involves the use of algorithms and data to analyze information and develop solutions. AI has the potential to revolutionize many aspects of our lives, from healthcare and transportation to business and entertainment.

Problem solving is a critical component of artificial intelligence (AI). AI systems are designed to solve complex, real-world problems by employing various problem-solving techniques and algorithms.

One of the main goals of AI is to create intelligent systems that can solve problems in a way that mimics human problem-solving abilities. This involves using algorithms to search through a vast amount of data and information to find the most optimal solution.

Problem solving in AI involves breaking down a problem into smaller, more manageable sub-problems. These sub-problems are then solved individually and combined to solve the larger problem at hand. This approach allows AI systems to tackle complex problems that would be impossible for a human to solve manually.

AI problem-solving techniques can be classified into two main categories: algorithmic problem-solving and heuristic problem-solving. Algorithmic problem-solving involves using predefined rules and algorithms to solve a problem. These algorithms are based on logical reasoning and can be programmed into AI systems to provide step-by-step instructions for solving a problem.

Heuristic problem-solving, on the other hand, involves using heuristics or rules of thumb to guide the problem-solving process. Heuristics are not guaranteed to find the optimal solution, but they can provide a good enough solution in a reasonable amount of time.

Problem solving in AI is not limited to just finding a single solution to a problem. AI systems can also generate multiple solutions and evaluate them based on predefined criteria. This allows AI systems to explore different possibilities and find the best solution among them.

In conclusion, problem solving is a fundamental aspect of artificial intelligence. AI systems use problem-solving techniques and algorithms to tackle complex real-world problems. Through algorithmic and heuristic problem solving, AI systems are able to find optimal solutions and generate multiple solutions for evaluation. As AI continues to advance, problem-solving abilities will play an increasingly important role in the development of intelligent systems.

Problem Solving Approaches in Artificial Intelligence

In the field of artificial intelligence, problem solving is a fundamental aspect. Artificial intelligence (AI) is the intelligence exhibited by machines or computer systems. It aims to mimic human intelligence in solving complex problems that require reasoning and decision-making.

What is problem solving?

Problem solving refers to the cognitive mental process of finding solutions to difficult or complex issues. It involves identifying the problem, gathering relevant information, analyzing possible solutions, and selecting the most effective one. Problem solving is an essential skill for both humans and AI systems to achieve desired goals.

Approaches in problem solving in AI

Artificial intelligence employs various approaches to problem solving. Some of the commonly used approaches are:

  • Search algorithms: These algorithms explore a problem space to find a solution. They can use different search strategies such as depth-first search, breadth-first search, and heuristic search.
  • Knowledge-based systems: These systems store and utilize knowledge to solve problems. They rely on rules, facts, and heuristics to guide their problem-solving process.
  • Logic-based reasoning: This approach uses logical reasoning to solve problems. It involves representing the problem as a logical formula and applying deduction rules to reach a solution.
  • Machine learning: Machine learning algorithms enable AI systems to learn from data and improve their problem-solving capabilities. They can analyze patterns, make predictions, and adjust their behavior based on feedback.

Each approach has its strengths and weaknesses, and the choice of approach depends on the problem domain and available resources. By combining these approaches, AI systems can effectively tackle complex problems and provide valuable solutions.

Search Algorithms in Problem Solving

Problem solving is a critical aspect of artificial intelligence, as it involves the ability to find a solution to a given problem or goal. Search algorithms play a crucial role in problem solving by systematically exploring the search space to find an optimal solution.

What is a Problem?

A problem in the context of artificial intelligence refers to a task or challenge that requires a solution. It can be a complex puzzle, a decision-making problem, or any situation that requires finding an optimal solution.

What is an Algorithm?

An algorithm is a step-by-step procedure or set of rules for solving a problem. In the context of search algorithms, it refers to the systematic exploration of the search space, where each step narrows down the possibilities to find an optimal solution.

Search algorithms in problem solving aim to efficiently explore the search space to find a solution. There are several types of search algorithms, each with its own characteristics and trade-offs.

One commonly used search algorithm is the Breadth-First Search (BFS) algorithm. BFS explores the search space by systematically expanding all possible paths from the initial state to find the goal state. It explores the search space in a breadth-first manner, meaning that it visits all nodes at the same depth level before moving to the next level.

Another popular search algorithm is the Depth-First Search (DFS) algorithm. Unlike BFS, DFS explores the search space by diving deep into a path until it reaches a dead-end or the goal state. It explores the search space in a depth-first manner, meaning that it explores the deepest paths first before backtracking.

Other search algorithms include the A* algorithm, which combines the efficiency of BFS with the heuristic guidance of algorithms; the Greedy Best-First Search, which prioritizes paths based on a heuristic evaluation; and the Hill Climbing algorithm, which iteratively improves the current solution by making small changes.

Search algorithms in problem solving are essential in the field of artificial intelligence as they enable systems to find optimal solutions efficiently. By understanding and implementing different search algorithms, developers and researchers can design intelligent systems capable of solving complex problems.

Search Algorithm Description
Breadth-First Search (BFS) Explores all possible paths at the same depth level before moving to the next level
Depth-First Search (DFS) Explores a path until it reaches a dead-end or the goal state, then backtracks
A* Algorithm Combines the efficiency of BFS with heuristic guidance
Greedy Best-First Search Prioritizes paths based on a heuristic evaluation
Hill Climbing Iteratively improves the current solution by making small changes

Heuristic Functions in Problem Solving

In the field of artificial intelligence, problem-solving is a crucial aspect of creating intelligent systems. One key component in problem-solving is the use of heuristic functions.

A heuristic function is a function that guides an intelligent system in making decisions about how to solve a problem. It provides an estimate of the best possible solution based on available information at any given point in the problem-solving process.

What is a Heuristic Function?

A heuristic function is designed to provide a quick, yet informed, estimate of the most promising solution out of a set of possible solutions. It helps the intelligent system prioritize its search and focus on the most likely path to success.

Heuristic functions are especially useful in problems that have a large number of possible solutions and where an exhaustive search through all possibilities would be impractical or inefficient.

How Does a Heuristic Function Work?

Heuristic functions take into account various factors and considerations that are relevant to the problem being solved. These factors could include knowledge about the problem domain, past experience, or rules and constraints specific to the problem.

The heuristic function assigns a value to each possible solution based on these factors. The higher the value, the more likely a solution is to be optimal. The intelligent system then uses this information to guide its search for the best solution.

A good heuristic function strikes a balance between accuracy and efficiency. It should be accurate enough to guide the search towards the best solution but should also be computationally efficient to prevent excessive computation time.

Advantages of Heuristic Functions Limitations of Heuristic Functions
1. Speeds up the problem-solving process 1. May lead to suboptimal solutions in certain cases
2. Reduces the search space 2. Relies on available information, which may be incomplete or inaccurate
3. Allows for efficient exploration of the solution space 3. Requires careful design and calibration for optimal performance

Overall, heuristic functions play a crucial role in problem-solving in artificial intelligence. They provide a way for intelligent systems to efficiently navigate complex problem domains and find near-optimal solutions.

Constraint Satisfaction in Problem Solving

Problem solving is a key component of artificial intelligence, as it involves using computational methods to find solutions to complex issues. However, understanding how to solve these problems efficiently is essential for developing effective AI systems. And this is where constraint satisfaction comes into play.

Constraint satisfaction is a technique used in problem solving to ensure that all solution candidates satisfy a set of predefined constraints. These constraints can be thought of as rules or conditions that must be met for a solution to be considered valid.

So, what is a constraint? A constraint is a limitation or restriction on the values that variables can take. For example, in a scheduling problem, constraints can include time availability, resource limitations, or precedence relationships between tasks.

The goal of constraint satisfaction in problem-solving is to find a solution that satisfies all the given constraints. This is achieved by exploring the space of possible solutions and eliminating those that violate the constraints.

Constraint satisfaction problems (CSPs) can be solved using various algorithms, such as backtracking or constraint propagation. These algorithms iteratively assign values to variables and check if the constraints are satisfied. If a constraint is violated, the algorithm backtracks and tries a different value for the previous variable.

One advantage of using constraint satisfaction in problem solving is that it provides a systematic way to represent and solve problems with complex constraints. By breaking down the problem into smaller constraints, it becomes easier to reason about the problem and find a solution.

In conclusion, constraint satisfaction is an important technique in problem solving for artificial intelligence. By defining and enforcing constraints, AI systems can efficiently search for valid solutions. Incorporating constraint satisfaction techniques into AI algorithms can greatly improve problem-solving capabilities and contribute to the development of more intelligent systems.

Genetic Algorithms in Problem Solving

Artificial intelligence (AI) is a branch of computer science that focuses on creating intelligent machines capable of performing tasks that typically require human intelligence. One aspect of AI is problem solving, which involves finding solutions to complex problems. Genetic algorithms are a type of problem-solving method used in artificial intelligence.

So, what are genetic algorithms? In simple terms, genetic algorithms are inspired by the process of natural selection and evolution. They are a type of optimization algorithm that uses concepts from genetics and biology to find the best solution to a problem. Instead of relying on a predefined set of rules or instructions, genetic algorithms work by evolving a population of potential solutions over multiple generations.

The process of genetic algorithms involves several key steps. First, an initial population of potential solutions is generated. Each solution is represented as a set of variables or “genes.” These solutions are then evaluated based on their fitness or how well they solve the problem at hand.

Next, the genetic algorithm applies operators such as selection, crossover, and mutation to the current population. Selection involves choosing the fittest solutions to become the parents for the next generation. Crossover involves combining the genes of two parents to create offspring with a mix of their characteristics. Mutation introduces small random changes in the offspring’s genes to introduce genetic diversity.

The new population is then evaluated, and the process continues until a stopping criterion is met, such as finding a solution that meets a certain fitness threshold or reaching a maximum number of generations. Over time, the genetic algorithm converges towards the best solution, much like how natural selection leads to the evolution of species.

Genetic algorithms have been successfully applied to a wide range of problem-solving tasks, including optimization, machine learning, and scheduling. They have been used to solve problems in areas such as engineering, finance, and biology. Due to their ability to explore a large solution space and find globally optimal or near-optimal solutions, genetic algorithms are often preferred when traditional methods fail or are not feasible.

In conclusion, genetic algorithms are a powerful tool in the field of artificial intelligence and problem solving. By mimicking the process of natural selection and evolution, they provide a way to find optimal solutions to complex problems. Their ability to explore a wide search space and adapt to changing environments makes them well-suited for a variety of problem-solving tasks. As AI continues to advance, genetic algorithms will likely play an increasingly important role in solving real-world problems.

Logical Reasoning in Problem Solving

Problem solving is a fundamental aspect of artificial intelligence. It involves finding a solution to a given problem by using logical reasoning. Logical reasoning is the process of using valid arguments and deductions to make inferences and arrive at a logical conclusion. In the context of problem solving, logical reasoning is used to analyze the problem, identify potential solutions, and evaluate their feasibility.

Logical reasoning is what sets artificial intelligence apart from other problem-solving approaches. Unlike human problem solvers, AI can analyze vast amounts of data and consider numerous possibilities simultaneously. It can also distinguish between relevant and irrelevant information and use it to make informed decisions.

Types of Logical Reasoning

There are several types of logical reasoning that AI systems employ in problem solving:

  • Deductive Reasoning: Deductive reasoning involves drawing specific conclusions from general principles or premises. It uses a top-down approach, starting from general knowledge and applying logical rules to derive specific conclusions.
  • Inductive Reasoning: Inductive reasoning involves drawing general conclusions or patterns from specific observations or examples. It uses a bottom-up approach, where specific instances are used to make generalizations.
  • Abductive Reasoning: Abductive reasoning involves making the best possible explanation or hypothesis based on the available evidence. It is a form of reasoning that combines deductive and inductive reasoning to generate the most likely conclusion.

Importance of Logical Reasoning in Problem Solving

Logical reasoning is crucial in problem solving as it ensures that the solutions generated by AI systems are sound, valid, and reliable. Without logical reasoning, AI systems may produce incorrect or nonsensical solutions that are of no use in practical applications.

Furthermore, logical reasoning helps AI systems analyze complex problems systematically and break them down into smaller, more manageable sub-problems. By applying logical rules and deductions, AI systems can generate possible solutions, evaluate their feasibility, and select the most optimal one.

In conclusion, logical reasoning plays a vital role in problem solving in artificial intelligence. It enables AI systems to analyze problems, consider multiple possibilities, and arrive at logical conclusions. By employing various types of logical reasoning, AI systems can generate accurate and effective solutions to a wide range of problems.

Planning and Decision Making in Problem Solving

Planning and decision making play crucial roles in the field of artificial intelligence when it comes to problem solving . A fundamental aspect of problem solving is understanding what the problem actually is and how it can be solved.

Planning refers to the process of creating a sequence of actions or steps to achieve a specific goal. In the context of artificial intelligence, planning involves creating a formal representation of the problem and finding a sequence of actions that will lead to a solution. This can be done by using various techniques and algorithms, such as heuristic search or constraint satisfaction.

Decision making, on the other hand, is the process of selecting the best course of action among several alternatives. In problem solving, decision making is essential at every step, from determining the initial state to selecting the next action to take. Decision making is often based on evaluation and comparison of different options, taking into consideration factors such as feasibility, cost, efficiency, and the desired outcome.

Both planning and decision making are closely intertwined in problem solving. Planning helps in breaking down a problem into smaller, manageable sub-problems and devising a strategy to solve them. Decision making, on the other hand, guides the selection of actions or steps at each stage of the problem-solving process.

In conclusion, planning and decision making are integral components of the problem-solving process in artificial intelligence. Understanding the problem at hand, creating a plan, and making informed decisions are essential for achieving an effective and efficient solution.

Challenges in Problem Solving in Artificial Intelligence

Problem solving is at the core of what artificial intelligence is all about. It involves using intelligent systems to find solutions to complex problems, often with limited information or resources. While artificial intelligence has made great strides in recent years, there are still several challenges that need to be overcome in order to improve problem solving capabilities.

Limited Data and Information

One of the main challenges in problem solving in artificial intelligence is the availability of limited data and information. Many problems require a large amount of data to be effective, but gathering and organizing that data can be time-consuming and difficult. Additionally, there may be cases where the necessary data simply doesn’t exist, making it even more challenging to find a solution.

Complexity and Uncertainty

Another challenge is the complexity and uncertainty of many real-world problems. Artificial intelligence systems need to be able to handle ambiguous, incomplete, or contradictory information in order to find appropriate solutions. This requires advanced algorithms and models that can handle uncertainty and make decisions based on probabilistic reasoning.

Intelligent Decision-Making

In problem solving, artificial intelligence systems need to be able to make intelligent decisions based on the available information. This involves understanding the problem at hand, identifying potential solutions, and evaluating the best course of action. Intelligent decision-making requires not only advanced algorithms but also the ability to learn from past experiences and adapt to new situations.

In conclusion, problem solving in artificial intelligence is a complex and challenging task. Limited data and information, complexity and uncertainty, and the need for intelligent decision-making are just a few of the challenges that need to be addressed. However, with continued research and advancement in the field, it is hoped that these challenges can be overcome, leading to even more effective problem solving in artificial intelligence.

Complexity of Problems

Artificial intelligence (AI) is transforming many aspects of our lives, including problem solving. But what exactly is the complexity of the problems that AI is capable of solving?

The complexity of a problem refers to the level of difficulty involved in finding a solution. In the context of AI, it often refers to the computational complexity of solving a problem using algorithms.

AI is known for its ability to handle complex problems that would be difficult or time-consuming for humans to solve. This is because AI can process and analyze large amounts of data quickly, allowing it to explore different possibilities and find optimal solutions.

One of the key factors that determines the complexity of a problem is the size of the problem space. The problem space refers to the set of all possible states or configurations of a problem. The larger the problem space, the more complex the problem is.

Another factor that influences the complexity of a problem is the nature of the problem itself. Some problems are inherently more difficult to solve than others. For example, problems that involve combinatorial optimization or probabilistic reasoning are often more complex.

Furthermore, the complexity of a problem can also depend on the available resources and the algorithms used to solve it. Certain problems may require significant computational power or specialized algorithms to find optimal solutions.

In conclusion, the complexity of problems that AI is capable of solving is determined by various factors, including the size of the problem space, the nature of the problem, and the available resources. AI’s ability to handle complex problems is one of the key reasons why it is transforming many industries and becoming an essential tool in problem solving.

Incomplete or Uncertain Information

One of the challenges in problem solving in artificial intelligence is dealing with incomplete or uncertain information. In many real-world scenarios, AI systems have to make decisions based on incomplete or uncertain knowledge. This can happen due to various reasons, such as missing data, conflicting information, or uncertain predictions.

When faced with incomplete information, AI systems need to rely on techniques that can handle uncertainty. One such technique is probabilistic reasoning, which allows AI systems to assign probabilities to different possible outcomes and make decisions based on these probabilities. By using probabilistic models, AI systems can estimate the most likely outcomes and use this information to guide problem-solving processes.

In addition to probabilistic reasoning, AI systems can also utilize techniques like fuzzy logic and Bayesian networks to handle incomplete or uncertain information. Fuzzy logic allows for the representation and manipulation of uncertain or vague concepts, while Bayesian networks provide a graphical representation of uncertain relationships between variables.

Overall, dealing with incomplete or uncertain information is an important aspect of problem solving in artificial intelligence. AI systems need to be equipped with techniques and models that can handle uncertainty and make informed decisions based on incomplete or uncertain knowledge. By incorporating these techniques, AI systems can overcome limitations caused by incomplete or uncertain information and improve problem-solving capabilities.

Dynamic Environments

In the field of artificial intelligence, problem solving is a fundamental task. However, in order to solve a problem, it is important to understand what the problem is and what intelligence is required to solve it.

What is a problem?

A problem can be defined as a situation in which an individual or system faces a challenge and needs to find a solution. Problems can vary in complexity and can be static or dynamic in nature.

What is dynamic intelligence?

Dynamic intelligence refers to the ability of an individual or system to adapt and respond to changing environments or situations. In the context of problem solving in artificial intelligence, dynamic environments play a crucial role.

In dynamic environments, the problem or the conditions surrounding the problem can change over time. This requires the problem-solving system to be able to adjust its approach or strategy in order to find a solution.

Dynamic environments can be found in various domains, such as robotics, autonomous vehicles, and game playing. For example, in a game, the game board or the opponent’s moves can change, requiring the player to adapt their strategy.

To solve problems in dynamic environments, artificial intelligence systems need to possess the ability to perceive changes, learn from past experiences, and make decisions based on the current state of the environment.

In conclusion, understanding dynamic environments is essential for problem solving in artificial intelligence. By studying how intelligence can adapt and respond to changing conditions, researchers can develop more efficient and effective problem-solving algorithms.

Optimization vs. Satisficing

In the field of artificial intelligence and problem solving, there are two main approaches: optimization and satisficing. These approaches differ in their goals and strategies for finding solutions to problems.

What is optimization?

Optimization is the process of finding the best solution to a problem, typically defined as maximizing or minimizing a certain objective function. In the context of artificial intelligence, this often involves finding the optimal values for a set of variables that satisfy a given set of constraints. The goal is to find the solution that maximizes or minimizes the objective function while satisfying all the constraints. Optimization algorithms, such as gradient descent or genetic algorithms, are often used to search for the best solution.

What is satisficing?

Satisficing, on the other hand, focuses on finding solutions that are good enough to meet a certain set of criteria or requirements. The goal is not to find the absolute best solution, but rather to find a solution that satisfies a sufficient level of performance. Satisficing algorithms often trade off between the quality of the solution and the computational resources required to find it. These algorithms aim to find a solution that meets the requirements while minimizing the computational effort.

Both optimization and satisficing have their advantages and disadvantages. Optimization is typically used when the problem has a clear objective function and the goal is to find the best possible solution. However, it can be computationally expensive and time-consuming, especially for complex problems. Satisficing, on the other hand, is often used when the problem is ill-defined or there are multiple conflicting objectives. It allows for faster and less resource-intensive solutions, but the quality of the solution may be compromised to some extent.

In conclusion, the choice between optimization and satisficing depends on the specific problem at hand and the trade-offs between the desired solution quality and computational resources. Understanding these approaches can help in developing effective problem-solving strategies in the field of artificial intelligence.

Ethical Considerations in Problem Solving

Intelligence is the ability to understand and learn from experiences, solve problems, and adapt to new situations. Artificial intelligence (AI) is a field that aims to develop machines and algorithms that possess these abilities. Problem solving is a fundamental aspect of intelligence, as it involves finding solutions to challenges and achieving desired outcomes.

The Role of Ethics

However, it is essential to consider the ethical implications of problem solving in the context of AI. What is considered a suitable solution for a problem and how it is obtained can have significant ethical consequences. AI systems and algorithms should be designed in a way that promotes fairness, transparency, and accountability.

Fairness: AI systems should not discriminate against any individuals or groups based on characteristics such as race, gender, or religion. The solutions generated should be fair and unbiased, taking into account diverse perspectives and circumstances.

Transparency: AI algorithms should be transparent in their decision-making process. The steps taken to arrive at a solution should be understandable and explainable, enabling humans to assess the algorithm’s reliability and correctness.

The Impact of AI Problem Solving

Problem solving in AI can have various impacts, both positive and negative, on individuals and society as a whole. AI systems can help address complex problems and make processes more efficient, leading to advancements in fields such as healthcare, transportation, and finance.

On the other hand, there can be ethical concerns regarding the use of AI in problem solving:

– Privacy: AI systems may collect and analyze vast amounts of data, raising concerns about privacy invasion and potential misuse of personal information.

– Job displacement: As AI becomes more capable of problem solving, there is a possibility of job displacement for certain professions. It is crucial to consider the societal impact and explore ways to mitigate the negative effects.

In conclusion, ethical considerations play a vital role in problem solving in artificial intelligence. It is crucial to design AI systems that are fair, transparent, and accountable. Balancing the potential benefits of AI problem solving with its ethical implications is necessary to ensure the responsible and ethical development of AI technologies.

What is Problems, Problem Spaces, and Search in AI?

Artificial intelligence (AI) ‘s initial goal is to build machines capable of carrying out tasks that usually call for human intelligence. Among the core functions of AI is real-life problem-solving. Understanding “problems,” “problem spaces,” and “search” is fundamental to comprehending how AI systems handle and resolve challenging jobs in the current situation.

In this article, we’ll explain the concepts of problem, problem space, and search in the context of artificial intelligence.

Table of Content

Problems in AI

Problem spaces in ai, search in ai, navigating a robot through a maze, what is problems, problem spaces, and search in ai – faqs.

A problem is a particular task or challenge that calls for decision-making or solution-finding. In artificial intelligence , an issue is simply a task that needs to be completed; these tasks can be anything from straightforward math problems to intricate decision-making situations. Artificial intelligence encompasses various jobs and challenges, from basic math operations to sophisticated ones like picture recognition, natural language processing, gameplay, and optimization. Every problem has a goal state that must be attained, a defined set of initial states, and potential actions or moves.

Important Components of Problems in AI

Here, we’ll see the important components of Problems in AI:

  • Initial State: The state of the issue as it first arises.
  • Goal State: The idealized final state that delineates a problem-solving strategy.
  • Operators: The collection of maneuvers or actions that can be used to change a state.
  • Restrictions: Guidelines or limitations must be adhered to to solve the problem.

Let’s an example, in a chess game, the pieces’ beginning positions on the board represent the initial state, a checkmate is the objective state, the permissible moves made by the pieces represent the operators, and the chess rules represent the constraints.

The set of all potential states, actions, and transitions that might arise when trying to solve a particular problem is known as the problem space. It depicts the whole range of feasible fixes and routes from the starting point to the desired destination. An abstract representation of every conceivable state and all possible transitions between them for a particular problem is called a problem space. It is a conceptual landscape in which all points signify various system states, and all possible operations or activities are represented by the paths connecting the points.

Important Components of Problem Spaces in AI

Here, we’ll see the important components of Problem Spaces in AI –

  • States: Every scenario or configuration that could arise within the issue.
  • State Space: The collection of all states that an operator sequence can apply to get from the starting state.
  • Paths: Paths are sets of states that connect the starting state to the destination state through operators.

In the case of route planning, for instance, the issue space consists of all potential locations on the map represented as states and all legitimate routes or paths connecting them as actions. For example, in a maze-solving problem, the problem space consists of the maze itself (state space), all potential positions within the maze (states), and the paths that travel from the start to the exit (paths) in the maze.

The practice of searching for a set of steps or movements that will get you to the desired outcome or a workable solution is known as a search. Within artificial intelligence, search algorithms are employed to methodically traverse the problem domain and identify routes or resolutions that fulfill the problem’s limitations and goals. Search algorithms are used in AI to effectively explore issue domains.

Types of Search in AI

Numerous search strategies exist, which can be generically categorized as informed (heuristic) and uninformed (blind).

1. Uninformed Search

Apart from the problem definition, these algorithms don’t know anything else about the states. Typical ignorant search tactics consist of –

  • Breadth-First Search (BFS) : Before going on to nodes at the next depth level, the Breadth-First Search (BFS) method investigates every node at the current depth.
  • Depth-First Search (DFS) : Investigates a branch as far as it can go before turning around.
  • Cost Search : To find the lowest-cost solution, uniform cost search expands the least-cost node.

2. Informed Search

These algorithms make use of heuristics or extra information to direct the search more effectively in the direction of the desired state. Typical knowledgeable search tactics consist of –

  • Greedy Best-First Search : Chooses the node that seems to be closest to the objective using a heuristic.
  • A* : Sums the projected cost from a node with the cost to get there.

Beginning with the original state, the search process investigates potential courses of action to produce new states. The most promising states to investigate further are then identified by evaluating these states according to specific criteria (such as cost, utility, or distance to the goal). Iteratively, the process is carried out until the desired condition is attained or a workable solution is discovered.

For a 5×5 maze, a robot starts at the top-left corner and aims to reach the bottom-right corner, avoiding walls and obstacles. Using BFS, the robot explores all possible moves layer by layer, ensuring the shortest path is found. The process continues until the robot reaches the goal.

Navigating a robot through a maze involves several key components:

  • Initial State: The robot’s starting position and orientation in the maze.
  • Goal State: The exit of the maze, defined by specific coordinates.
  • Operators: Possible actions the robot can take, such as moving forward, backward, turning left, and turning right.
  • Constraints: Walls and obstacles that the robot cannot pass through, which define valid moves.
  • Problem Space: All possible states the robot can occupy, including all positions and orientations within the maze.
  • Breadth-First Search (BFS): Explores all neighbors at the current depth before moving deeper, guaranteeing the shortest path in unweighted mazes.

Navigating a maze requires defining initial and goal states, possible moves, constraints, and choosing an appropriate search strategy. This systematic approach allows the robot to efficiently find a path from the start to the exit. Different strategies balance memory use, speed, and optimality based on the problem’s specific requirements.

To sum up, the foundation of AI problem-solving is comprised of the ideas of problems, problem spaces, and search. In AI issue solving, efficient search algorithms are crucial for efficiently navigating vast and intricate problem spaces and locating ideal or nearly ideal answers. They offer an organized method for defining, investigating, and resolving complicated tasks, which makes it possible to create intelligent systems with efficacy and efficiency comparable to that of humans. The development of AI technologies still depends heavily on our continued understanding and advancement of these ideas.

What is the main difference between problem space and search space in AI?

The set of all possible states or configurations that an issue can assume is known as the problem space, and the set of all paths or operations that can be used to transition between states within the problem space is known as the search space. This organised issues into operations, aims, and givens.

Can the Problem be broken down in AI?

If a problem can be divided into more manageable, standalone subproblems, it is said to be decomposable. Decomposable difficulties can be resolved by addressing each subproblem separately. Then, the answers to the different subproblems can be merged to resolve the main issue.

What is the role of Knowledge in AI?

Depending on the complexity and type of the problem, knowledge plays a different role in problem-solving. Understanding is essential for directing the process of fixing problems. Extensive domain-specific knowledge is necessary in certain problems in order to identify patterns, restrictions, and potential solutions. For instance, to make wise moves in chess, one must have a thorough understanding of the game’s rules and strategic concepts.

AI accelerates problem-solving in complex scenarios

apply problem solving algorithm to measure performance in ai

A new, data-driven approach could lead to better solutions for tricky optimization problems like global package routing or power grid operation.

While Santa Claus may have a magical sleigh and nine plucky reindeer to help him deliver presents, for companies like FedEx, the optimization problem of efficiently routing holiday packages is so complicated that they often employ specialized software to find a solution.

This software, called a mixed-integer linear programming (MILP) solver, splits a massive optimization problem into smaller pieces and uses generic algorithms to try and find the best solution. However, the solver could take hours — or even days — to arrive at a solution.

The process is so onerous that a company often must stop the software partway through, accepting a solution that is not ideal but the best that could be generated in a set amount of time.

Researchers from MIT and ETH Zurich used machine learning to speed things up.

They identified a key intermediate step in MILP solvers that has so many potential solutions it takes an enormous amount of time to unravel, which slows the entire process. The researchers employed a filtering technique to simplify this step, then used machine learning to find the optimal solution for a specific type of problem.

Their data-driven approach enables a company to use its own data to tailor a general-purpose MILP solver to the problem at hand.

This new technique sped up MILP solvers between 30 and 70 percent, without any drop in accuracy. One could use this method to obtain an optimal solution more quickly or, for especially complex problems, a better solution in a tractable amount of time.

This approach could be used wherever MILP solvers are employed, such as by ride-hailing services, electric grid operators, vaccination distributors, or any entity faced with a thorny resource-allocation problem.

“Sometimes, in a field like optimization, it is very common for folks to think of solutions as either purely machine learning or purely classical. I am a firm believer that we want to get the best of both worlds, and this is a really strong instantiation of that hybrid approach,” says senior author Cathy Wu, the Gilbert W. Winslow Career Development Assistant Professor in Civil and Environmental Engineering (CEE), and a member of a member of the Laboratory for Information and Decision Systems (LIDS) and the Institute for Data, Systems, and Society (IDSS).

Wu wrote the paper with co-lead authors Siriu Li, an IDSS graduate student, and Wenbin Ouyang, a CEE graduate student; as well as Max Paulus, a graduate student at ETH Zurich. The research will be presented at the Conference on Neural Information Processing Systems.

Tough to solve

MILP problems have an exponential number of potential solutions. For instance, say a traveling salesperson wants to find the shortest path to visit several cities and then return to their city of origin. If there are many cities which could be visited in any order, the number of potential solutions might be greater than the number of atoms in the universe.

“These problems are called NP-hard, which means it is very unlikely there is an efficient algorithm to solve them. When the problem is big enough, we can only hope to achieve some suboptimal performance,” Wu explains.

An MILP solver employs an array of techniques and practical tricks that can achieve reasonable solutions in a tractable amount of time.

A typical solver uses a divide-and-conquer approach, first splitting the space of potential solutions into smaller pieces with a technique called branching. Then, the solver employs a technique called cutting to tighten up these smaller pieces so they can be searched faster.

Cutting uses a set of rules that tighten the search space without removing any feasible solutions. These rules are generated by a few dozen algorithms, known as separators, that have been created for different kinds of MILP problems.

Wu and her team found that the process of identifying the ideal combination of separator algorithms to use is, in itself, a problem with an exponential number of solutions.

“Separator management is a core part of every solver, but this is an underappreciated aspect of the problem space. One of the contributions of this work is identifying the problem of separator management as a machine learning task to begin with,” she says.

Shrinking the solution space

She and her collaborators devised a filtering mechanism that reduces this separator search space from more than 130,000 potential combinations to around 20 options. This filtering mechanism draws on the principle of diminishing marginal returns, which says that the most benefit would come from a small set of algorithms, and adding additional algorithms won’t bring much extra improvement.

Then they use a machine-learning model to pick the best combination of algorithms from among the 20 remaining options.

This model is trained with a dataset specific to the user’s optimization problem, so it learns to choose algorithms that best suit the user’s particular task. Since a company like FedEx has solved routing problems many times before, using real data gleaned from past experience should lead to better solutions than starting from scratch each time.

The model’s iterative learning process, known as contextual bandits, a form of reinforcement learning, involves picking a potential solution, getting feedback on how good it was, and then trying again to find a better solution.

This data-driven approach accelerated MILP solvers between 30 and 70 percent without any drop in accuracy. Moreover, the speedup was similar when they applied it to a simpler, open-source solver and a more powerful, commercial solver.

In the future, Wu and her collaborators want to apply this approach to even more complex MILP problems, where gathering labeled data to train the model could be especially challenging. Perhaps they can train the model on a smaller dataset and then tweak it to tackle a much larger optimization problem, she says. The researchers are also interested in interpreting the learned model to better understand the effectiveness of different separator algorithms.

The process of problem-solving is frequently used to achieve objectives or resolve particular situations. In computer science, the term "problem-solving" refers to artificial intelligence methods, which may include formulating ensuring appropriate, using algorithms, and conducting root-cause analyses that identify reasonable solutions. Artificial intelligence (AI) problem-solving often involves investigating potential solutions to problems through reasoning techniques, making use of polynomial and differential equations, and carrying them out and use modelling frameworks. A same issue has a number of solutions, that are all accomplished using an unique algorithm. Additionally, certain issues have original remedies. Everything depends on how the particular situation is framed.

Artificial intelligence is being used by programmers all around the world to automate systems for effective both resource and time management. Games and puzzles can pose some of the most frequent issues in daily life. The use of ai algorithms may effectively tackle this. Various problem-solving methods are implemented to create solutions for a variety complex puzzles, includes mathematics challenges such crypto-arithmetic and magic squares, logical puzzles including Boolean formulae as well as N-Queens, and quite well games like Sudoku and Chess. Therefore, these below represent some of the most common issues that artificial intelligence has remedied:

Depending on their ability for recognising intelligence, these five main artificial intelligence agents were deployed today. The below would these be agencies:

This mapping of states and actions is made easier through these agencies. These agents frequently make mistakes when moving onto the subsequent phase of a complicated issue; hence, problem-solving standardized criteria such cases. Those agents employ artificial intelligence can tackle issues utilising methods like B-tree and heuristic algorithms.

The effective approaches of artificial intelligence make it useful for resolving complicated issues. All fundamental problem-solving methods used throughout AI were listed below. In accordance with the criteria set, students may learn information regarding different problem-solving methods.

The heuristic approach focuses solely upon experimentation as well as test procedures to comprehend a problem and create a solution. These heuristics don't always offer better ideal answer to something like a particular issue, though. Such, however, unquestionably provide effective means of achieving short-term objectives. Consequently, if conventional techniques are unable to solve the issue effectively, developers turn to them. Heuristics are employed in conjunction with optimization algorithms to increase the efficiency because they merely offer moment alternatives while compromising precision.

Several of the fundamental ways that AI solves every challenge is through searching. These searching algorithms are used by rational agents or problem-solving agents for select the most appropriate answers. Intelligent entities use molecular representations and seem to be frequently main objective when finding solutions. Depending upon that calibre of the solutions they produce, most searching algorithms also have attributes of completeness, optimality, time complexity, and high computational.

This approach to issue makes use of the well-established evolutionary idea. The idea of "survival of the fittest underlies the evolutionary theory. According to this, when a creature successfully reproduces in a tough or changing environment, these coping mechanisms are eventually passed down to the later generations, leading to something like a variety of new young species. By combining several traits that go along with that severe environment, these mutated animals aren't just clones of something like the old ones. The much more notable example as to how development is changed and expanded is humanity, which have done so as a consequence of the accumulation of advantageous mutations over countless generations.

Genetic algorithms have been proposed upon that evolutionary theory. These programs employ a technique called direct random search. In order to combine the two healthiest possibilities and produce a desirable offspring, the developers calculate the fit factor. Overall health of each individual is determined by first gathering demographic information and afterwards assessing each individual. According on how well each member matches that intended need, a calculation is made. Next, its creators employ a variety of methodologies to retain their finest participants.

In this tutorial we learn about ways to measure performance of an Algorithm . By measuring performance of an algorithm we can determine which algorithm is better than the other one. Performance of an algorithm is usually represented by the Big O Notation . Follow along and learn more about measuring performance of an algorithm .

I am in a Big problem!

I just received a birthday gift from my elder sister and I want to send a thank you message to her. But, the thing is I am running short on time. I want to get this task done as soon as possible. I’ve listed three ways in which I can solve this problem.

1) Sending a thank you note through post/mail.

2) I could ring her phone or compose an email to convey the message.

3) Or drive to her house and thank her in person.

But, which approach do you think would be fastest?

Approach 2, right? Yes, I was thinking the same.

My end goal of sending a thank you message can be easily accomplished by few clicks or a with one phone call.( Big assumption: Gossip time on the phone not counted )

Similarly, in order to solve any problem in computer science, we write programs. Every program — though can be written in a different programming language — like the one discussed above, can be solved in many ways. In the programming world, we call these ways/solutions as Algorithms .

What is an algorithm?

Oh, yeah, big word alert: What is an algorithm?  An algorithm is nothing but a bunch of steps we undertake to achieve some goal, sister getting a thank you message in our above example. Let’s take our third approach to send thank you message to big sister.

Wait, you might be wondering, does that count as an algorithm? Sure it does!

Similarly, before jumping to write a program in computer science, we always write an algorithm; a bunch of steps required to accomplish the task or solve the problem .

But, you may ask: We had multiple solutions to our thank you message problem. How do we decide/analyze which algorithm is fastest and best to solve our problem?

Analysis of Algorithm? How do we analyze them?

Before I answer your previous questions, let’s try to solve an immediate issue which popped up. I will get back to how do we go about analyzing algorithm after solving this immediate issue.

Imagine this, you just joined a new development team and were given a piece of code. As you look through the code, you find two methods sort_1 and sort_2 . Both these methods take same input in the form of an array of unsorted integer . And the function/method returns a sorted array i.e integers returned are in an order. Without going into code details, we can write the pseudo code as

Something like Input Given: An array of unsorted numbers like [8, 2, 10, 1]

Output Expected: Sorted array like [1, 2, 8, 10]

Someone from the team comes and tells you, “ Ah, one of this sorting method is faster than the other. But which one I can’t remember. Can you find out for me ? ”

Newbies can’t say no. So, time to put on our Testing Caps.

Something which is very clear is that we still don’t know any full proof approach which will give us an accurate result. We might have to do a repeated test to get a good average result.

Measuring performance by measuring time

Test Plan : Let’s create an array of 100 random numbers. Let us call this sort_1 function inside a loop which runs 1,000 times and log time taken to sort numbers. Refer to the below pseudo code:

Test Result: After running this test, you’ll find, log times are pretty close.A difference of few percents maybe. We've got a fair idea how long these functions/methods each take to sort 100 numbers.

Side Note: The small difference in time is because sorting 100 numbers is a fairly small task for machines. Any algorithm you choose, unless extremely inefficient, you will find a difference of a few milliseconds only.

But, did it solve our problem yet? We still can’t figure out which one is fastest or better than other.

Time for Test 2:

Test Plan: Instead of creating 100 random numbers and calling the sort function 1000 times, why not create a single large random number array and call the sort function only once.

Test Result : Ah, this test did the job for us. With the humongous amount of data, you may find that one method beats other. Not just by few percents. Rather by a dramatic huge margin. One method could sort the array within a fraction of seconds and other is still sorting it for us.

I am sure you might be wondering is this even possible?

Factors on Which Algorithm Run time Depends

So, let me break this to you: this kind of result is not at all unusual. And this is one of the major reason and core challenges one faces with algorithm analysis.

The ( correct ) algorithms we write are neither slow or fast in itself. It would be very easy that way. It also very much depends on how much data we are asking these algorithms to work on .

My Computer Vs. SuperComputer

But, I ran both these tests on my computer. What if, I ran this algorithm on a supercomputer. Will the result still be same?

Factors like the speed of the processor, programming language used to implement it and  hardware will drastically impact the run time of the algorithm.

So, now the main question is: how do we go about analyzing/measuring/estimating the time taken by algorithms to run ignoring low-level hardware details and subject to varied input sizes?

( Also, problem fondly known as how do we go about measuring Time Complexity of an algorithm)

Not-So-Boring-Math to the rescue!

Mathematical notation called as Big O Notation/ Big O Complexity at our rescue.

What is Big O Notation?

What the heck is Big O Notation?

In computer science, we use Big O to classify algorithm where we express how quickly the run-time or space requirements grows relative to input , as the input size grows arbitrarily large .

Let me break the definition down into simpler words:

  • Measuring Run time/Time Complexity Of An Algorithm:

Sorry, it’s difficult to jot down the exact run time of an algorithm. Why you may ask. Remember, our computer vs supercomputer issue. Different hardware, processor speed affects total run-time of the algorithm. So instead of talking about run time directly, we use Big O to talk about how quickly the run time grows when the data ( read: input ) given to our algorithm increases.

  • Run time could be expressed in terms of seconds, but how do we measure the growth of run time?

Yes, I agree logging time would have been hassle free. But, since, we’re measuring how quickly our run time grows, we need to measure speed in terms of something else.

In Big O , we use the :

  • size of the input/data which we denote as “n”
  • O stands for the order

So, you’d often find us saying, “ Hey, the run time of that algorithm grows on the order of the size of the input i.e O(n) ”.  Or something like, “ on the order of the square of the size of the input i.e O(n²) ”.

If all this explanation seems abstract so far, don’t worry. Let’s look at some examples analyzing our code with Big-O notation for more clarity.

Real Life Big O:

When analyzing algorithms/operations, we often consider the worst-case scenario . What’s the worst that can happen to our algorithm and when does our algorithm will do some serious heavy-lifting work?

Let’s say you have a cabinet full of files. You may have many tasks like finding files, getting rid of duplicates etc. You also know that if there are more files in the cabinet, longer it will take you to accomplish your task.

Assuming we’ve to perform some of the task mentioned above. Here are few scenarios and ways in which we can find the file from the cabinet and their corresponding order of notation( operation’s time complexity ).

O(n) — Linear Time :

Scenario/Problem : Let's say we want to find a particular file in the cabinet. But, the files stored in the cabinet are not sorted or alphabetized. How can we search for our file?

Approach: We will have to look at each and every file present in the cabinet till we can find our file.

Worst-Case Scenario & Complexity Explanation:

  • In the worst case scenario, we will have to look at n files. (n is highest no of files present in the cabinet)
  • The number of steps we take is directly related to your input size. Means if the cabinet had 10 files, we have to look at all 10 files till we find our file in our worst-case scenario .
  • Hence, we say, the run-time of above algorithm grows on the order of the size of the input i.e O(n).
  • Single for loops, linear search are examples of linear time

O(1) — Constant Time :

Scenario/Problem : You need a file and remember exact location where you had kept the file.

Approach : Open the cabinet, pick the file from the location. End of the story.

  • *The above method runs in O(1) time relative to its input. *
  • The input array could be 1 item or 1,000 items, but since we know where our element resides, retrieving it would just require one “ step ”.
  • Picking element by array index is an example of constant time.

O(n²) — Quadratic Time :

Scenario/Problem : You’ve duplicate files in the cabinet and you want to remove them. But, you’ve no idea how many duplicate copies of each file lies in the cabinet.

Approach : We will have to pick the first file, check it against all the other files. Then take file number 2 and repeat the same action until you got to the last file.

  • In the worst case scenario, we will have to look n² times, comparing each and every file with the others.
  • Each pass to outer loop O(n) requires going through entire array through the inner-loop which is another O(n) operation.
  • Nested for-loops are an example of quadratic time complexity

O(log n) — Logarithmic time :

Scenario: The files in the cabinet are in the order. We’ve to search a file marked with a label .

Approach : We can start in the middle, see in which half should be in, go to the middle of the half and repeat the steps until we found our file.

  • When our files were not ordered, we had to see each and every file resulting in an O(n) time complexity.
  • But, since the files are ordered, here, given an input of size n, the number of steps it takes to accomplish the task are decreased by roughly 50% each time through the algorithm. (If you do the math, it works out to be an O(log n) operation)
  • O (log N) algorithms are very efficient because increasing amount of data has little effect at some point early on because the amount of data is halved on each run through.
  • Recursive algorithm like binary search is an example of logarithmic complexity .

Just drop the constants & less significant terms:

Let’s take a small algorithm where we’ve to calculate the complexity of the equation by throwing away:

  • Leading constants
  • Less significant terms.

big O notation

Why we do this?

If you can remember or scroll back to the definition of Big O, there’s a term in bold which states that when input size( n ) grows arbitrarily large.

As n gets really big, adding 200 or dividing by 10 has a decreasingly significant effect. So, we can safely throw these terms out. We only concentrate on a principal activity which has the most impact.

 big-o

What is Space Complexity?

( I know, I know this is the biggest Big O definition explanation in the history of mankind. This is the final concept I promise! )

We need to analyze or care about memory cost( space complexity ) just like we did for our precious time. Best part there isn’t much difference between them.

Space complexity is space taken by algorithm to complete its algorithm relative to its input size.

Space Complexity = Constant Space + Auxiliary Space

  • Constant Space is generally fixed for an algorithm. Think of the space taken by local variables and input variables.
  • Auxiliary Space is extra/temporary/additional space used by an algorithm. Mostly temporary variables.

Let’s see few code examples to simplify our definition:

O(1) Space Complexity :

We know, Space complexity = Constant Space + Auxiliary Space

Constant space is local variables & inputs i.e variable x, y, z and r in our case.

Auxiliary Space is for the temporary variable. Not used in above example. We consider 1 unit for each variable present in our algorithm

Space complexity = 1 + 1 + 1 + 1 + 0 = 4 = O(1) ( remember, our constant time Big O notation? )

O(n) Space Complexity:

Now, above method has an input of array and another input gives size/length of that array. An array has n elements, each will hold 1 unit of memory. So space taken by an array is ( 1n ) where n = number of elements in the array

Constant space = Space taken by array + variable n + variable r

Auxiliary Space = Space taken by temporary variable i

Space Complexity = (n * 1) + 1 + 1 + 1 = O(n)

This is awesome except:

Big O is a powerful tool, but one should use it wisely. Sometimes there’s a tradeoff between saving time and saving space , so one has to take a crucial decision on what needs to be optimized.

Like Big O royally ignores constants and less significant terms. But, sometimes they matter too. Imagine, if we have got a script that goes on for 5 hours, an optimization that divides the runtime by 10 might not affect Big O, but it can still save us few hours of waiting. Also, beware of premature optimization.

Hence, it is rightly said that one must develop the skill to optimize time and space complexity as well as be wise enough to judge if these optimizations are worthwhile.

Closing Notes:

  • Big O time and space complexity usually deal with mathematical notation. This article aimed at covering the topic in simpler language, more by code and engineering way. Feel free to check out pure mathematical notation here
  • Also, to solve our time complexity problem, we’ve three types of Asymptotic notation.1) Θ Notation 2) Big O Notation 3) Ω Notation. We looked at Big O as it is most widely used asymptotic notation. And also, it deals with worst-case, something we need in efficiency tradeoff .

How does AI work?

AI mimics human intelligence using algorithms and data. These processes rely on machine learning, where computers learn patterns and make decisions without necessarily being programmed for each scenario. Think of it like teaching a computer to recognize cats in pictures: instead of giving it a list of rules about what makes a cat, you’d show it pictures of cats and let it learn the common features on its own. 

There are different types of AI, but one common approach is supervised learning. In this method, the computer is given a dataset with labeled examples, like pictures of cats and dogs with labels saying which is which. It uses these examples to learn the patterns and make predictions on new, unseen data. 

Another important aspect of AI is neural networks, which are inspired by the human brain. These neural networks have layers of interconnected nodes, each processing and transforming data differently. Through training, neural networks adjust the connections between nodes to improve their performance on specific tasks.
