Class PISAHypervolume

java.lang.Object

org.uma.jmetal.util.naming.impl.SimpleDescribedEntity

org.uma.jmetal.qualityindicator.hypervolume.impl.PISAHypervolume

All Implemented Interfaces:

Serializable, Hypervolume, QualityIndicator, DescribedEntity

public class PISAHypervolume
extends SimpleDescribedEntity
implements Hypervolume

Created by ajnebro on 19/4/15. This class implements the hypervolume indicator. The code is a Java version of the original metric implementation by Eckart Zitzler. Reference: E. Zitzler and L. Thiele. Multiobjective Evolutionary Algorithms: A Comparative Case Study and the Strength Pareto Approach, IEEE Transactions on Evolutionary Computation, vol. 3, no. 4, pp. 257-271, 1999.
