Question

I want to write a code in python to solve a sudoku puzzle. Do you guys have any idea about a good algorithm for this purpose. I read somewhere in net about a algorithm which

Hi I've blogged about writing a sudoku solver from scratch in Python and currently writing a whole series about writing a constraint programming solver in Julia (another high level but faster language) You can read the sudoku problem from a file which seems to be easier more handy than a gui or cli way. The general idea it uses is constraint programming. I use the all different / unique constraint but I coded it myself instead of using a constraint programming solver.
