Knight’s Tour Algorithm

The main goal of Knight’s Tour is to visit each tile of chessboard of size n (n > 4) only once using knight.

Example showing path for board of size 8 (8×8).

It can be achieved using Warnsdorf’s rule – in each step knight should visit tile, which has the lowest moves possible:

For n = 5 board:
