I have a working program based on [1] that sets up all different constraints for each row, column and box and then sets exact sum constraints for each cage. It'll run in around 0.2 secs for a simple problem, but a tough one takes 2 hours 45 minutes. I did some research into improving the performance and found [2] but can't work out how to implement the constraints given. Can someone please help, assuming that it's even possible. [1] http://pypi.python.org/pypi/python-constraint/1.1 [2] http://4c.ucc.ie/~hsimonis/sudoku.pdf -- Cheers. Mark Lawrence.
