Class UnaryHyperVolume

java.lang.Object
  jeco.kernel.qualityIndicators.UnaryHyperVolume

public class UnaryHyperVolume
extends java.lang.Object

This class implements the unary hypervolume indicator as proposed in Zitzler, E., and Thiele, L. (1998): Multiobjective Optimization Using Evolutionary Algorithms - A Comparative Case Study. Parallel Problem Solving from Nature (PPSN-V), 292-301. A more detailed discussion can be found in Zitzler, E., Thiele, L., Laumanns, M., Fonseca, C., and Grunert da Fonseca, V (2003): Performance Assessment of Multiobjective Optimizers: An Analysis and Review. IEEE Transactions on Evolutionary Computation, 7(2), 117-132. IMPORTANT: A lower indicator value corresponds to a better approximation set.
