IloSolutionDeltaCheckI

In some instances, the illegality of a solution delta can be determined before the delta is applied to the solution in question, if knowledge of the problem is available. This abstract implementation class can be used to perform such specialized “pre-filtering”, which can improve the performance of local search procedures considerably.

The method IloMetaHeuristic::getDeltaCheck returns a delta checker which uses the method IloMetaHeuristicI::isFeasible to perform such checks. Therefore, it is not necessary to subclass IloSolutionDeltaCheck to perform delta checks for metaheuristics.

Constructor and Destructor Summary
`public`	`IloSolutionDeltaCheckI(IloEnv env)`
`public`	`~IloSolutionDeltaCheckI()`

Method Summary
`public IloEnv`	`getEnv() const`
`public virtual IloBool`	`ok(IloSolver solver, IloSolution delta) const`

This constructor creates an instance of the IloSolutionDeltaCheckI class.

~IloSolutionDeltaCheckI

Since IloSolutionDeltaCheckI is an abstract class, a virtual destructor is provided.

getEnv

This member function returns the environment specified when the invoking object was constructed.

This member function is called with the delta to be checked. If delta is determined to be illegal, this member should return IloFalse. Otherwise, it returns IloTrue.
