Method Detail

getCPtr

protected static long getCPtr(KNumObjectiveOptimalityChecker obj)

finalize

protected void finalize()

Overrides:

finalize in class KOptimalityToleranceChecker

delete

public void delete()

Overrides:

delete in class KOptimalityToleranceChecker

isGoodEnough

public boolean isGoodEnough(double bestSolutionObj,
                            double bestBound)

Description copied from class: KOptimalityToleranceChecker

Check for the optimality tolearance

Overrides:

isGoodEnough in class KOptimalityToleranceChecker

Parameters:

bestSolutionObj -

bestBound -

Returns:

true is the best solution is close enough - for some criteria - to the optimum

nextBoundToTry

public double nextBoundToTry(double bestSolutionObj)

Description copied from class: KOptimalityToleranceChecker

Returns a bound to set on the objective, in order to look for solution which are not too close from the
current best known solution. This prevent from storing too many solutions which are very similar.

Overrides:

nextBoundToTry in class KOptimalityToleranceChecker

Parameters:

bestSolutionObj - the best objective value of already found solutions.

Returns:

a bound to set on the objective.
