Class GeneralTerminationCondition<V extends Variable<V,T>,T extends Value<V,T>>

java.lang.Object

org.cpsolver.ifs.termination.GeneralTerminationCondition<V,T>

Type Parameters:

V - Variable

T - Value

All Implemented Interfaces:

TerminationCondition<V,T>

public class GeneralTerminationCondition<V extends Variable<V,T>,T extends Value<V,T>>
extends Object
implements TerminationCondition<V,T>

General implementation of termination condition.

Solver stops when the solution is complete (all varaibles are assigned) or when a timeout is reached (expressed either by the number of iterations or by a time).

Parameters:
