The 8-puzzle is an old game largely used to test new heuristic AI techniques.

The software solves any 8-puzzle combination (even and odd) using "board counting".
An even combination will find the following objective:
012
345
678

An odd combination will find the following objective:
123
804
765

How to run the program:

1. Extract files from "8puzzle.zip" in FOLDER.
2. Change MATLAB location to FOLDER.
3. Run the file "StartGame.m" from MATLAB.
4. Enter a 3 X 3 matrix. ex. [3 2 1, 4 5 6 , 0 8 7]
5. Wait for the solution.

can you please help me implementing BFS for this game?
The "one-row sliding-tile puzzle" consists of three black tiles, three white tiles, and an empty space in the middle as shown below.

initial state : B B B 0 W W W
goal state : W W W B B B 0

The puzzle has two kinds of legal moves with associated costs: A tile may move into an adjacent location. This has a cost of 1. A tile can hop over one or two other tiles into the empty position. This has a cost equal to the number of tiles jumped over.
