Class UnaryEpsilon

java.lang.Object
  jeco.kernel.qualityIndicators.UnaryEpsilon

public class UnaryEpsilon
extends java.lang.Object

This class iimplements the unary epsilon indicator as proposed 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.
