Class BulkFitnessFunction

java.lang.Object

org.jgap.BulkFitnessFunction

All Implemented Interfaces:

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

Direct Known Subclasses:

public abstract class BulkFitnessFunction
extends java.lang.Object
implements java.io.Serializable, ICloneable

Bulk fitness functions are used to determine how optimal a group of solutions are relative to each other. Bulk fitness functions can be useful (vs. normal fitness functions) when fitness of a particular solution cannot be easily computed in isolation, but instead is dependent upon the fitness of its fellow solutions that are also under consideration. This abstract class should be extended and the evaluateChromosomes() method implemented to evaluate each of the Chromosomes given in an array and set their fitness values prior to returning.
