Constraint Propagation technique actually modifies the CSP problem. A. True B. False

The correct answer is False. Constraint propagation is a technique used in constraint satisfaction problems (CSPs) to reduce the search space by removing values that cannot be assigned to variables. It does not modify the CSP problem itself, but rather the set of possible solutions.

Constraint propagation works by iteratively checking the constraints between variables and removing values that cannot be assigned to variables without violating any constraints. For example, if the constraints are
