Class Epsilon

java.lang.Object
  jmetal.qualityIndicator.Epsilon

public class Epsilon
extends java.lang.Object

This class implements the unary epsilon additive indicator as proposed in E. Zitzler, E. Thiele, L. Laummanns, M., Fonseca, C., and Grunert da Fonseca. V (2003): Performance Assesment of Multiobjective Optimizers: An Analysis and Review. The code is the a Java version of the original metric implementation by Eckart Zitzler. It can be used also as a command line program just by typing $java jmetal.qualityIndicator.Epsilon
