Class Individual

java.lang.Object
  edu.udo.cs.yale.operator.features.Individual

public class Individual
extends java.lang.Object

Individuals contain all necessary informations about example sets for population based search heuristics, including the performance. Each individiual can also handle a crowding distance for multi-objecitve optimization approaches.
