Class TNichedMutation

java.lang.Object

keel.Algorithms.Genetic_Rule_Learning.XCS.TNichedMutation

All Implemented Interfaces:

TernaryMutation

public class TNichedMutation
extends java.lang.Object
implements TernaryMutation

This class applies the niched mutation. So, the changes made in the classifier cannot result in another classifier that does not match with the environment (we can change a don't care for the value of the parent, or a value for a don't care value, but, for example, we would never changer a '0' for a '1').
