No. While forward checking is a subset of arc consistency, after any assignment, arc consistency may have already eliminated values in a previous step that are eliminated in that step by forward checking. Thus, enforcing arc consistency will never leave more domain values than enforcing forward checking, but on a given fort spinney sandown

WebDon't use strings to represent bits. I scanned over your code very quickly and the first thing to stick out was that you are using strings called domains all over the place. These domains are used as an array of characters, each of which is a possibility left in a row/column/box. Each domain starts with the value "123456789" and then characters are stripped from … WebJul 24, 2024 · csp backtracking-search forward-checking backtracking-algorithm mac-algorithm Updated on Jul 24, 2024 Python chanioxaris / kenken-solver Star 18 Code … WebCMU School of Computer Science dinosaur with head fin
