Sudoku represented by colors

Ever solved a Sudoku puzzle by hand?  It’s a painful process, and I don’t wish it upon anyone.  Ever solved a Sudoku puzzle using an Aritifical Intelligence algorithm?  It’s also a painful process, but in the end you’ll have a useful tool for understanding permutation based search spaces.

Below are several articles/posts I’ve written on solving the Sudoku puzzle using variations of over-the-counter A.I. algorithms.  Each article assumes a certain amount of A.I. knowledge, and a good grip on your programming skills.  In addition to this, you’ll find general information on Sudoku, mathematical proofs, computational theory, and code samples.  All I ask for in return is your input and questions regarding the material.  If you have a method that you’d like to post, or think I should link to, then please email me.
