Algorithm::Evolutionary::Op::Uniform_Crossover - interchanges a set of atoms from one parent to the other.


  #Create from XML description using EvoSpec
  my $xmlStr3=<<EOC;
  <op name='Uniform_Crossover' type='binary' rate='1'>
    <param name='numPoints' value='3' /> #Max is 2, anyways
  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::Uniform_Crossover 0.5;# Crossover rate

Base Class



General purpose uniform crossover operator


new( [$options_hash] [, $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 = { crossover_rate => 0.5 }; my $priority = 1;

apply( $chromsosome_1, $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 String.

Changes the first parent, and returns it. If you want to change both parents at the same time, check QuadXOver
