Note that the "official" way to solve sudoku is to use "dancing links", but I guess you are creating a naive implementation precisely as a base-line against which to measure other implementations?
Well, Dancing Links (DLX) is just a data structure + few techniques to help with the backtrack, after modeling Sudoku as a contraint satisfaction problem. You can write a backtracking algorithm that is at least as fast as DLX :-) -- Vimal
