Class OverallConstraintViolationComparator
java.lang.Object
jmetal.util.comparators.OverallConstraintViolationComparator
- All Implemented Interfaces:
- java.util.Comparator, IConstraintViolationComparator
public class OverallConstraintViolationComparator
- extends java.lang.Object
- implements IConstraintViolationComparator
This class implements a Comparator
(a method for comparing
Solution
objects) based on the overall constraint violation of
the solucions, as in NSGA-II.
