public class DefaultInheritedAssignment<V extends Variable<V,T>,T extends Value<V,T>>
extends DefaultParallelAssignment<V,T>
implements InheritedAssignment<V,T>

Default inherited assignment. This assignment is based on DefaultParallelAssignment and creates a full copy of the given assignment during its creation. This inherited assignment is slower than OptimisticInheritedAssignment, but more reliable. Useful for small problems with a lot of constraints.
