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 … WebA part of algorithms for CSP are forward algorithms. They are used to check consistency and constraint propagation. The most famous forward algorithm, is forward checking algorithm (FCA). In this article we are going to introduce FCA and suggest two algorithms to improve efficiency of forward.
