# How you can solve 8-puzzle problem using hill climbing search?

## How you can solve 8-puzzle problem using hill climbing search?

Step 1: Evaluate the initial state, if it is goal state then return success and Stop. Step 2: Loop Until a solution is found or there is no new operator left to apply. Step 3: Select and apply an operator to the current state.

## How do you solve an 8-puzzle problem using a star algorithm?

The puzzle can be solved by moving the tiles one by one in the single empty space and thus achieving the Goal configuration. The tiles in the initial(start) state can be moved in the empty space in a particular order and thus achieve the goal state.

What are the problems associated with hill climbing algorithm explain with solution?

A hill-climbing algorithm which never makes a move towards a lower value guaranteed to be incomplete because it can get stuck on a local maximum. And if algorithm applies a random walk, by moving a successor, then it may complete but not efficient.

### What is meant by 8-puzzle problem?

The 8-puzzle problem is a puzzle invented and popularized by Noyes Palmer Chapman in the 1870s. It is played on a 3-by-3 grid with 8 square blocks labeled 1 through 8 and a blank square. Your goal is to rearrange the blocks so that they are in order.

### How many operators can there be to solve the 8-puzzle problem?

– 8‐puzzle: we could specify 4 possible moves for each of the 8 cles, resulcng in a total of 4*8=32 operators.

How do you solve a puzzle problem?

Basic steps to solve Logical Puzzles

1. Take a quick look at the question.
2. Develop a general idea regarding the theme of the problem.
3. Select the data that is giving you some concrete information out of total information given. Also, select the data which helps in ruling out certain possibilities.

## Which algorithm is used in 8-puzzle problem?

A* Algorithm is one of the best and popular techniques used for path finding and graph traversals. A lot of games and web-based maps use this algorithm for finding the shortest path efficiently. It is essentially a best first search algorithm.

## What is hill climbing problem?

Hill Climbing is a heuristic search used for mathematical optimization problems in the field of Artificial Intelligence. Given a large set of inputs and a good heuristic function, it tries to find a sufficiently good solution to the problem. This solution may not be the global optimal maximum.

Which algorithm is used to solve any kind of problem?

Which algorithm is used to solve any kind of problem? Explanation: Tree algorithm is used because specific variants of the algorithm embed different strategies.

### How do you know if an 8-puzzle is unsolvable?

Following is simple rule to check if a 8 puzzle is solvable. It is not possible to solve an instance of 8 puzzle if number of inversions is odd in the input state. In the examples given in above figure, the first example has 10 inversions, therefore solvable. The second example has 11 inversions, therefore unsolvable.

### Why do we solve puzzles?
