A challenge like this seems to be for folks who are both very good programmers and even better chess players.
:P
i tried a little bit with 8 queens only (just by looking a chess board, not coding) and i didn't get it! :redface:
:lol:
I will pay 1 million for 2 queens on a 2x2 chessboard. Anyone? ;)
I'll pay a billion for a solution on 3 x 3 board !!
felipe, here are two hints
1. Place the queens separated by knight's moves to start. Of course it's not that simple, but in all solutions, there are many knight's moves between queens.
2. Really, it's very easy - for me, anyway. No big deal. The solution is trivial! Just google it. This is guaranteed to work! Thank you, thank you <applause>
An hour trying to find a process without sucess. Just 15 minutes looking the chessboard, and I have a solution... but not the process! 8)
Later: like RRR say, the solution is valid for queens (and number of cells by side) >= 4
