Class IfLessThanZero

java.lang.Object
  org.jgap.gp.CommandGene
      examples.gp.paintedDesert.IfLessThanZero

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable

public class IfLessThanZero
extends CommandGene

A three argument version of if-less-than-zero (IFLTZ) construct. If the first argument is less than zero, then return the second argument, else the return the third argument. Mimics the Lisp function from Koza.
