I didn't know Excel has an ILP solver; cute. Can it solve sudokus? A pure ILP doesn't need any brute force at the surface, i.e. the branch and bound strategy handles that below the surface but even my cplex solver takes a few seconds to come up with a solution. My brute force silly solver in the Java articles section is much, much faster.
kind regards,

edit. I happen to have a 2007 version of excel and it explicitly mentions a sudoku solver in its help files; here it is. I tried it; it is pure crap.
