I improved the speed and strength of my solver and it finishes the 36638 puzzles of http://www.csse.uwa.edu.au/~gordon/sudoku17 in 3885 seconds. It can solve all but 164 without guessing, and averages greater 9 puzzles per second on a 1.33 GHz PPC Mac OS X laptop using ghc-6.4.2

Is this the DLX solver on the wiki?

Not quite. This is an optimized, bug-fixed, and more powerful solver. I will update the wiki version soon. -- Chris
