Sudoku Collaboration Project: Discussion

[Merri]

Source code thread


Original post:
It is easy to make a sudoku solver with a backtracker, ie. by guessing values and see if solving succeeds by throwing a guess. Now, how about making a solver that doesn't use these "easy" methods of solving at all? Although, I guess there is already atleast one algorithm that can solve any sudoku entirely without any guessing, but that doesn't mean we can't code it again.

The question is: do people want to go for a challenge (contest without a prize) or for a collaboration project, where people first make codes on their own and then start looking into which way it is good to go, suggesting ideas etc. freely, eventually aiming for a full sudoku solver with a nice interface and so on (so there would be other aspects to the solver other than just algorithms).

Challenge could be changed to a real contest if I can donate my own prize from the last sudoku solver contest: custom title with HTML formatting. I never claimed that prize.
