Class RFreeMutation

java.lang.Object

keel.Algorithms.Genetic_Rule_Learning.XCS.RFreeMutation

All Implemented Interfaces:

RealMutation

public class RFreeMutation
extends java.lang.Object
implements RealMutation

This class implements the free mutation. So, a gene can be changed for any valid value in the representation.

Method Detail

mutateLower

public double mutateLower(double lowerValue,
                          double upperValue,
                          double currentState)

Mutates the lower real value.

Specified by:

mutateLower in interface RealMutation

Parameters:

lowerValue - is the current lower value of this classifier position

upperValue - is the current upper value of this classifier position.

currentState - is the current State of the environment for this allele of the classifier.

Returns:

a double with the mutated value

mutateUpper

public double mutateUpper(double lowerValue,
                          double upperValue,
                          double currentState)

Mutates the upper real value.

Specified by:

mutateUpper in interface RealMutation

Parameters:

lowerValue - is the current lower value of this classifier position

upperValue - is the current upper value of this classifier position.

currentState - is the current State of the environment for this allele of the classifier.

Returns:

a double with the mutated value.
