Csp forward checking
WebMar 14, 2024 · CSP algorithms were introduced in order to shrink the large space and boost the algorithms. With good Forward Checking algorithms and consistent heuristic functions, high speed problem solving with low memory requirement would be possible. I hope you find this article useful.

Formally, a CSP has a few attributes: A set of n variables X = ... forward checking. In forward checking, when some variable is assigned value, backtracking search does the following two things: It calculates each unassigned variable that neighbors that variable.

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.
