  org.jgap.FitnessFunction
      examples.distinctGenes.SampleFitnessFunction

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable, ICloneable

public class SampleFitnessFunction
extends FitnessFunction

Fitness function for our example. It's without sense, it's just to demonstrate how to evaluate a chromosome with 40 4-field-genes and one 3-field gene. Each toplevel-gene is a CompositeGene, each "field" within a CompositeGene is a BooleanGene here (arbitrarily chosen).

Since:

3.0
