Algorithm::Evolutionary::Op::Crossover - n-point crossover operator; puts fragments of the second operand into the first operand
#Create from XML description using EvoSpec my $xmlStr3=<<EOC; <op name='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 $offspring = $op3->apply( $indi2, $indi3 ); #$indi2 == $offspring #Initialize using OO interface my $op4 = new Algorithm::Evolutionary::Op::Crossover 2; #Crossover with 2 crossover points
Algorithm::Evolutionary::Op::Base
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
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;
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.
_str
Changes the first parent, and returns it. If you want to change both parents at the same time, check QuadXOver
