I could be wrong but, yes, it does use backtracking to find the constraint that can give a number for an empty cell but it never has to change a number it has put in a cell. To guess and backtrack but a definite breach of puzzle manners The common characteristic for all constraints, here and elsewhere, Used sudoku(1) has options to control the combinations. Tradeoffs between depth/breadth first search and the constraints With constraint propagation to prune the search for the nextīest move (forms of forward checking.) There are space/time The solver uses depth first and/or breadth first tree search I shared the link because I found his sudoku generator and the constraint methods interesting. You are right that "the purpose of many the constraint techniques seem to be aimed at creating puzzles that are amenable to humans, not solving them" ) familiarity with Prolog terminology will be helpful. For more advanced material, look at the clp(FD) papers by Danial Diaz (. "The Art of the Propagator" ( ) is also good, though it focuses more on arithmetic value propagation than set propagation problems like sudoku. ![]() If you want to read more about constraint programming, there is an excellent overview chapter in CTM ( ). Coding up strategies like this is a possible route, but would require hundreds of lines of code (there are dozens of these strategies), and we'd never be sure if we could solve every puzzle." For example, the naked twins strategy looks for two squares in the same unit that both have the same two possible digits. " We could try to code more sophisticated strategies. He acknowledges the possibility of using more "reasoning" in the article, but dismisses it: Rather, it's removing every possibility that has already been canceled out (constraint propagation), then saving undo information, making one guess, and seeing if that sets off another chain reaction or reaches a solution. It isn't enumerating every combination of values and backtracking (as either a non-contstraint Prolog program or a C program with up to 81 nested for-loops would). I wouldn't call constraint propagation "brute-force".
