Class Summary

Class	Description
ConstraintViolationComparator<S extends Solution<?>>	This class implements a Comparator (a method for comparing Solution objects) based on the overall constraint violation of the solutions, as done in NSGA-II.
DirScoreComparator<S extends Solution<?>>	created at 10:34 pm, 2019/1/28 The comparator of DIR score used in D-NSGA-II
DominanceComparator<S extends Solution<?>>	This class implements a solution comparator taking into account the violation constraints
DominanceComparatorV2<S extends Solution<?>>	This class implements a solution comparator for dominance checking
DoubleVariableComparator
EpsilonDominanceComparator<S extends Solution<?>>	This class implements a solution comparator taking into account the violation constraints and an optional epsilon value (i.e, implements an epsilon dominance comparator)
EqualSolutionsComparator<S extends Solution<?>>	This class implements a Comparator (a method for comparing Solution objects) based whether all the objective values are equal or not.
FitnessComparator<S extends Solution<?>>	This class implements a Comparator (a method for comparing Solution objects) based on the fitness value returned by the method getFitness.
GDominanceComparator<S extends Solution<?>>	This class implements a solution comparator according to the concept of g-dominance (https://doi.org/10.1016/j.ejor.2008.07.015)
