  +--jaga.evolve.SinglePointXOver

All Implemented Interfaces:

GeneticOperator, java.io.Serializable

public class SinglePointXOver

extends java.lang.Object

implements GeneticOperator

Performs sexual single point cross over on a pair of individuals to create another.

It handles variable length genotypes.

Method Summary

void	operate(Selector selector, Population oldPopulation, Population newPopulation, int howMany) method that adds genotypes to the new population by extracting some from the old one and manipulating them in some way.
void	shiftOver(int pos, BitSet childMum, BitSet dad) unconventional sexual reproduction between genotypes: first genotype gets shifted to allow space for part of second one to replace hole.

Method Detail

xOver

public void xOver(int pos,
                  BitSet childMum,
                  BitSet dad)

performs genotype cross over between two bitsets

Parameters:

pos - position at which to cross over

childMum - in/out parameter who is one of parents and will also be child

dad - in parameter, the other parent

operate

public void operate(Selector selector,
                    Population oldPopulation,
                    Population newPopulation,
                    int howMany)

method that adds genotypes to the new population by extracting some from the old one and manipulating them in some way.

Specified by:

operate in interface GeneticOperator

Parameters:

oldPopulation - in parameter having all the original genotypes

newPopulation - in/out parameter where the next generation of genotypes is being built

howMany - how many new genotypes to add to the new population

shiftOver

public void shiftOver(int pos,
                      BitSet childMum,
                      BitSet dad)

unconventional sexual reproduction between genotypes: first genotype gets shifted to allow space for part of second one to replace hole. Makes sense when logic can be more useful in different parts of the genotype.

Parameters:

pos - position at which to shift over

childMum - in/out parameter who is one of parents and will also be child

dad - in parameter, the other parent

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
