in reply to Find solution to knight's tour

a bit of recursive backtracking might work. My CS lecturer didn't require checkpoints. IIRC my (java) solution worked for board sizes up to 6x6, then took too long (or crashed) for 7x7, but worked for 8x8. I never bothered to find out why. Although I may be getting confused with the killer queens puzzle. I should really have a look at both again in perl.

    I realize this post is old, but I just came across it and wanted to post a reply in case someone else came across it and wondered why your 7x7 board did not work. For m x m boards, there is no closed tour when m is odd.
