get2DHV

public double get2DHV(List<? extends Solution> solutionSet)

Computes the HV of a solution list. REQUIRES: The problem is bi-objective REQUIRES: The setArchive is ordered in descending order by the second objective

Returns:

computeHVContributions

public void computeHVContributions(List<? extends Solution> solutionList)

Computes the HV contribution of the solutions

computeSolutionHVContribution

public double computeSolutionHVContribution(List<? extends Solution> solutionList,
                                            int solutionIndex,
                                            double solutionSetHV)

Computes the HV contribution of a solutiontype in a solutiontype set. REQUIRES: the solutiontype belongs to the solutiontype set REQUIRES: the HV of the solutiontype set is computed beforehand and its value is passed as third parameter

Returns:

The hv contribution of the solutiontype
