NAME

Algorithm::Evolutionary::Op::Uniform_Crossover_Diff - Uniform crossover, but interchanges only those atoms that are different

SYNOPSIS

  my $xmlStr3=<<EOC;
  <op name='Uniform_Crossover_Diff' type='binary' rate='1'>
    <param name='numPoints' value='2' /> #Max is 2, anyways
  </op>
  EOC
  my $ref3 = XMLin($xmlStr3);

  my $op3 = Algorithm::Evolutionary::Op::Base->fromXML( $ref3 );
  print $op3->asXML(), "\n";

  my $indi = new Algorithm::Evolutionary::Individual::BitString 10;
  my $indi2 = $indi->clone();
  my $indi3 = $indi->clone(); #Operands are modified, so better to clone them
  $op3->apply( $indi2, $indi3 );

  my $op4 = new Algorithm::Evolutionary::Op::Uniform_Crossover_Diff 1; #Uniform_Crossover_Diff with 1 crossover points

Base Class

Algorithm::Evolutionary::Op::Base

DESCRIPTION

Crossover operator for a GA acting only on those bits that are different.

METHODS

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( $parent_1, $parent_2 )

Same as Algorithm::Evolutionary::Op::Uniform_Crossover, but making sure that what is interchanged is different.
