Brute force is so fast that there's no really any point in trying to solve it 
any other way except for the challenge of doing so. I answered a question on 
this using D at codegolf.stackexchange.com a while back:

http://codegolf.stackexchange.com/questions/378/implement-a-brute-force-
sudoku-solver/402#402

and the code is lightning fast. It would probably have to be tweaked to match 
whatever Bearophile's code does though as far is input goes (I haven't looked 
at the code that he linked to). It also makes no attempt at being compact 
(e.g. it actually checks the command line arguments). It's at just over 150 
lines and could be much shorter if I really tried to properly golf it rather 
than just solve the problem.
