Although I am sure there is a nice algorithm for this solution I still
have not found it. I have managed to solve it by brute force only.

By resetting the puzzle I usually find a fairly easy one to solve within
a few minutes.

OBJECTIVE: Swap the Black and White Knights.

Solution: I've solved this through brute force. It took enough moves
that I don't plan to document it here.
