## What is 8-puzzle problems explain this with the help of example?

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 8-puzzle problem can be formulated as an AI problem?**

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.
