POE::Component::Algorithm::Evolutionary::Island - Base class for evolutionary "islands" that interchange information with each other
use POE::Component::Algorithm::Evolutionary::Island; use Algorithm::Evolutionary qw( Individual::BitString Op::Creator Op::CanonicalGA Op::Bitflip Op::Crossover Op::GenerationalTerm Fitness::Royal_Road); my $bits = shift || 64; my $block_size = shift || 4; my $pop_size = shift || 256; #Population size my $numGens = shift || 200; #Max number of generations my $selection_rate = shift || 0.2; #Initial population my $creator = new Algorithm::Evolutionary::Op::Creator( $pop_size, 'BitString', { length => $bits }); # Variation operators my $m = Algorithm::Evolutionary::Op::Bitflip->new( 1 ); my $c = Algorithm::Evolutionary::Op::Crossover->new(2, 4); # Fitness function: create it and evaluate my $rr = new Algorithm::Evolutionary::Fitness::Royal_Road( $block_size ); my $generation = Algorithm::Evolutionary::Op::CanonicalGA->new( $rr , $selection_rate , [$m, $c] ) ; my $gterm = new Algorithm::Evolutionary::Op::GenerationalTerm 10; my @peers = qw( peer_1 peer_2 peer_3 ); # Different way of specifying peers, depending on implementation POE::Component::Algorithm::Evolutionary::Island::TypeXXX->new( Fitness => $rr, Creator => $creator, Single_Step => $generation, Terminator => $gterm, Alias => 'Canonical', Peers => \@peers ); $poe_kernel->run();
Not a lot here: it creates a component that uses POE to run an evolutionary algorithm
POE::Component::Algorithm::Evolutionary->new( Fitness => $rr, Creator => $creator, Single_Step => $generation, Terminator => $gterm, Alias => 'Canonical', Peers => \@peers);
Basically like PoCoAE, but with peers
Not to be called from outside, is the one that does the actual interchange between islands.
POE::Component::Algorithm::Evolutionary requires no configuration files or environment variables.
Main dependence is Algorithm::Evolutionary; however, it's not included by default, since you must pick and choose the modules you are going to actually use.
None reported.
No bugs have been reported.
