Package org.uma.jmetal.operator.mutation.impl

Class CDGMutation

java.lang.Object

org.uma.jmetal.operator.mutation.impl.CDGMutation

All Implemented Interfaces:

Serializable, MutationOperator<DoubleSolution>, Operator<DoubleSolution,DoubleSolution>

public class CDGMutation
extends Object
implements MutationOperator<DoubleSolution>

This class implements a polynomial mutation operator The implementation is based on the NSGA-II code available in http://www.iitk.ac.in/kangal/codes.shtml If the lower and upper bounds of a variable are the same, no mutation is carried out and the bound value is returned.
