The reflex agents are known as the simplest agents because they directly map states into actions. Unfortunately, these agents fail to operate in an environment where the mapping is too large to store and learn. Goal-based agent, problem solving in artificial intelligence, on the other hand, considers future actions and the desired outcomes. Problem solving in artificial intelligence, we will discuss one type of goal-based agent known as a problem-solving agentwhich uses atomic representation with no internal states visible to the problem-solving algorithms.

According to computer science, a problem-solving is a part of artificial intelligence which encompasses a number of techniques such as algorithms, heuristics to solve a problem. Therefore, a problem-solving agent is a goal-driven agent and focuses on satisfying the goal. Note: Initial state, actionsand transition model together define the state-space of the problem implicitly.

State-space of a problem is a set of all states which can be reached from the initial state followed by any sequence of actions. The state-space forms a directed map or graph where nodes are the states, links between the nodes are actions, and the path is a sequence of states connected by the sequence of actions.

In the above figure, our problem solving in artificial intelligence is to convert the current Start state into goal state by sliding digits into the blank space. Note: The 8-puzzle problem is a type of sliding-block problem which is used for testing new search algorithms in artificial intelligence.

It is noticed problem solving in artificial intelligence the above figure that each queen is set into the chessboard in a position where no other queen is placed diagonally, in same row or column.

Therefore, it is one right approach to the 8-queens problem, problem solving in artificial intelligence. In this formulation, there is approximately 1. This formulation is better than the incremental formulation as it reduces the state space from 1.

For solving different kinds of problem, an agent makes use of different strategies to reach the goal by searching the best possible algorithms. This process of searching is known as search strategy. Before discussing different search strategies, the performance measure of an algorithm should be measured.

Consequently, there are four ways to measure the performance of an algorithm:. Completeness: It measures if the algorithm guarantees to find a solution if any solution exist. The complexity of an algorithm depends on branching factor or maximum number of successorsdepth of the shallowest goal node i. This type of search strategy does not have any additional information about the states except the information provided in the problem definition.

They can only generate the successors and distinguish a goal state problem solving in artificial intelligence a non-goal state. This type of search strategy contains some additional information about the states beyond the problem definition.

This search uses problem-specific knowledge to find more efficient solutions, problem solving in artificial intelligence. This search maintains some sort of internal states via heuristic functions which provides hintsproblem solving in artificial intelligence, so it is also called heuristic search. Problem-solving agent The problem-solving agent perfoms precisely by defining problems and its several solutions. Steps performed by Problem-solving agent Goal Formulation: It is the first and simplest step in problem-solving.

Problem Formulation: It is the most important step of problem-solving which decides what actions should be taken to achieve the formulated goal.

There are following five components involved in problem formulation: Initial State: It is the starting state or initial step of the agent towards its goal. Actions: It is the description of the possible actions available to the agent. Transition Model: It describes what each action does. Goal Test: It determines if the given state is a goal state. Path cost: It assigns a numeric cost to each path that follows the goal.

The problem-solving agent selects a cost function, which reflects its performance measure. Remember, an optimal solution has the lowest path cost among all the solutions. Search: It identifies all the best possible sequence of actions to reach the goal state from the current state.

It takes a problem as an input and returns solution as its output. Solution: It finds the best algorithm out of various algorithms, which may be proven as the best optimal solution. Execution: It executes the best optimal solution from the searching algorithms to reach the goal state from the current state.

Example Problems Basically, there are two types of problem approaches: Toy Problem: It is a concise and exact description of the problem which is used by the researchers to compare the performance of algorithms. Real-world Problem: It is real-world based problems which require solutions. Unlike a toy problem, it does not depend on descriptions, but we can have problem solving in artificial intelligence general formulation of the problem.

The tile adjacent to the blank space can slide into that space. The objective is to reach a specified goal state similar to the goal state, as shown in the below figure. In the figure, our task is to convert the current state into goal state by sliding digits into the blank space.

### Problem Solving with Artificial Intelligence Requires Higher Compute Artificial intelligence must have access to objects, categories, properties and relations between all of them to implement knowledge engineering. Initiating common sense, reasoning and problem-solving power in machines is a difficult and tedious task. Machine learning is also a core part of AI. May 12,  · Some of the activities computers with artificial intelligence are designed for include: Speech recognition. Learning. Planning. Problem solving. In chapter one, we discussed a few factors that demonstrate intelligence. Problem solving was one of them when we referred to it using the examples of a. mouse searching a maze and the next number in the sequence problem. Historically people viewed the phenomena of intelligence as strongly related to. problem solving.
