Class Organism

java.lang.Object
  |
  +--sdt.ga.Organism

public abstract class Organism

extends java.lang.Object

implements java.io.Serializable, Task

This is the base class which represents an individual in a GA. This is the class every Organism has to extend in order to implement its own GA. The Fitness class has to be extended also along with this.

Constructor Detail

Organism

public Organism()

Method Detail

newInstance

protected final void setFitness(Fitness fitness)

This methods assigns the calculated fitness to the organism.
