What is the 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.
What is 8 tile puzzle problem in AI?
Solution: The puzzle can be solved by moving the tiles one by one in the single empty space and thus achieving the Goal state. Instead of moving the tiles in the empty space we can visualize moving the empty space in place of the tile. The empty space cannot move diagonally and can take only one step at a time.
How do you solve a 15 puzzle?
Solving this puzzle is not hazardous in any way that I know of.
- Step 1: Move the 1 Tile and the 2 Tile Into Their Final Positions.
- Step 2: Move Tiles 3 and 4 Into Setup Positions.
- Step 3: Move Tiles 3 and 4 Into Final Position.
- Step 4: Move Tiles 5 and 6 Into Final Position.
- Step 5: Move Tiles 7 and 8 Into Setup Positions.
How do I know if an instance of 15 puzzle is solvable?
Hence it is easy to prove by induction that any state of the puzzle for which the above sum is odd cannot be solvable. In particular, if the empty square is in the lower right corner (even anywhere in the last row) then the puzzle is solvable if and only if the number of inversions of the numbered pieces is even.
What is the solution to the 8 puzzle problem?
In this puzzle solution of the 8 puzzle problem is discussed. Given a 3×3 board with 8 tiles (every tile has one number from 1 to 8) and one empty space. The objective is to place the numbers on tiles to match the final configuration using the empty space.

How to solve the 8 puzzle problem using branch and bound?
In this puzzle solution of 8 puzzle problem is discussed. Given a 3×3 board with 8 tiles (every tile has one number from 1 to 8) and one empty space. The objective is to place the numbers on tiles to match final configuration using the empty space. We can slide four adjacent (left, right, above and below) tiles into the empty space.
How to find the final state of an 8 puzzle game?
Given an initial state of 8-puzzle game and a final state of to be reached, find the most cost-effective path to reach the final state from initial state. Let us consider the Manhattan distance between the current and final state as the heuristic for this problem statement.
