NAME

Algorithm::Evolutionary::Op::CX (Cycle crossover) - 2-point crossover operator; Builds offspring in such a way
that each gene comes from one of the parents. Preserves the absolute position of the elements
in the parent sequence

CONTENTS

SYNOPSIS



  my $op4 = new Algorithm::Evolutionary::Op::CX 3;

  my $indi = new Algorithm::Evolutionary::Individual::Vector 10;
  my $indi2 = $indi->clone();
  my $indi3 = $indi->clone();
  $op3->apply( $indi2, $indi3 );



Base Class

Algorithm::Evolutionary::Op::Base

DESCRIPTION

Cycle Crossover operator for a GA. It is applied to chromosomes that are a permutation of each other; even as the class it applies to is Algorithm::Evolutionary::Individual::Vector, it will issue lots of La jodimos! messages if the parents do not fulfill this condition.

Some information on this operator can be obtained from this evolutionary computation tutorial <http://www.cs.bham.ac.uk/~rmp/slide_book/node4.html#SECTION00444300000000000000>

METHODS

    new

Creates a new Algorithm::Evolutionary::Op::CX operator.

    create

Creates a new Algorithm::Evolutionary::Op::CX operator. But this is just to have a non-empty chromosome

    apply

Applies Algorithm::Evolutionary::Op::CX operator to a Chromosome, a bitstring, really. Can be applied only to victims with the _bitstring instance variable; but it checks before application that both operands are of type Individual::Vector.
