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

Class IntegerPolynomialMutation

java.lang.Object

org.uma.jmetal.operator.mutation.impl.IntegerPolynomialMutation

All Implemented Interfaces:

Serializable, MutationOperator<IntegerSolution>, Operator<IntegerSolution,IntegerSolution>

public class IntegerPolynomialMutation
extends Object
implements MutationOperator<IntegerSolution>

This class implements a polynomial mutation operator to be applied to Integer solutions If the lower and upper bounds of a variable are the same, no mutation is carried out and the bound value is returned. A RepairDoubleSolution object is used to decide the strategy to apply when a value is out of range.
