Class IFreeMutation

java.lang.Object

keel.Algorithms.Genetic_Rule_Learning.XCS.IFreeMutation

All Implemented Interfaces:

IntegerMutation

public class IFreeMutation
extends java.lang.Object
implements IntegerMutation

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

Method Detail

mutateLower

public int mutateLower(int lowerValue,
                       int upperValue,
                       int currentState,
                       int scale)

Mutates the lower real value.

Specified by:

mutateLower in interface IntegerMutation

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.

scale - values scale.

Returns:

a double with the mutated value

mutateUpper

public int mutateUpper(int lowerValue,
                       int upperValue,
                       int currentState,
                       int scale)

Mutates the upper real value.

Specified by:

mutateUpper in interface IntegerMutation

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.

scale - values scale.

Returns:

a double with the mutated value.
