This is another program that I wrote in Maple when I was teaching myself the language. I basically wanted to write a sudoku solver that used no methods that I am incapable of using when I solve and doesn't guess. It basically follows the same logic that I use when I try to solve sudokus. I have a sudoku calendar that my cousin gave me for Christmas. It solves the 5 star sudokus on my calendar and approximately 50% of the "evil" sudokus on www.websudoku.com.
