WebApr 5, 2024 · 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. It deletes every value from the domain of each neighboring variable that’s inconsistent with the new value of that variable. WebI have produced this, and found that my code must be very inefficient as it's a lot slower than just backtracking, even on complex problems. Any advice on how I should implement the … WebSince code inside if TYPE_CHECKING: is not executed at runtime, it provides a convenient way to tell mypy something without the code being evaluated at runtime.
