WebConstraint Satisfaction 3 Constraint satisfaction problems (CSPs) Standard search problem: state is a "black box“ – any data structure that supports successor function, heuristic function, and goal test CSP: state is defined by variables X i with values from domain Di goal test is a set of constraints specifying allowable combinations of values for WebJan 19, 2024 · Constraints are defined using a Constraint class. Each Constraint consists of the variables it constrains and a method that checks whether it’s satisfied (). The determination of whether a constraint is satisfied is the main logic that goes into defining a specific constraint-satisfaction problem.
