NAME

Algorithm::Evolutionary::Op::Gene_Boundary_Crossover - n-point crossover
operator that restricts crossing point to gene boundaries

CONTENTS

SYNOPSIS



  #Create from XML description using EvoSpec
  my $xmlStr3=<<EOC;
  <op name=Gene_Boundary_Crossover type=binary rate=1>
    <param name=numPoints value=3 /> #Max is 2, anyways
  </op>
  EOC
  my $op3 = Algorithm::Evolutionary::Op::Base->fromXML( $xmlStr3 );
  print $op3->asXML(), "\n";

  #Apply to 2 Individuals of the String class
  my $indi = new Algorithm::Evolutionary::Individual::BitString 10;
  my $indi2 = $indi->clone();
  my $indi3 = $indi->clone();
  my $offspring = $op3->apply( $indi2, $indi3 ); #$indi2 == $offspring

  #Initialize using OO interface
  my $op4 = new Algorithm::Evolutionary::Op::Gene_Boundary_Crossover 3; #Gene_Boundary_Crossover with 3 crossover points



Base Class

Algorithm::Evolutionary::Op::Base

DESCRIPTION

Crossover operator for a Individuals of type Algorithm::Evolutionary::Individual::String and their descendants (Algorithm::Evolutionary::Individual::BitString). Crossover for Algorithm::Evolutionary::Individual::Vector would be Algorithm::Evolutionary::Op::VectorCrossover

METHODS

new( [$options_hash] [, CW$operation_priority] )

Creates a new n-point crossover operator, with 2 as the default number of points, that is, the default would be
my $options_hash = { numPoints => 2 };
my $priority = 1;

    create( [$num_points] )

Creates a new 1 or 2 point crossover operator. But this is just to have a non-empty chromosome Defaults to 2 point

apply( CW$chromsosome_1, CW$chromosome_2 )

Applies xover operator to a Chromosome, a string, really. Can be applied only to victims with the _str instance variable; but it checks before application that both operands are of type BitString.
