Class AttainmentSurface

java.lang.Object
  jeco.kernel.qualityIndicators.AttainmentSurface

public class AttainmentSurface
extends java.lang.Object

This class takes R approximation sets as input and outputs a number of uniformly distributed points on the Jth (J less or equal than R) attainment surface. The method of computing the points is inspired by the article: Smith, Everson and Fieldsend (2004) "Dominance measures for multiobjective simulated annealing", Proc. CEC 2004, IEEE Press, pp. 23-30. For each point constructed on a lattice, the algorithm checks how many surfaces strictly dominate it, and how many just dominate it (including weakly and strictly). If the desired attainment surface is the Jth one, then if #strict is less than J and #dom is greater or equal than J then the point is plotted, else it is "discarded".
