"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. " - Cryptarithmetic column constraints
