NAME
Algorithm::Evolutionary::Op::Replace_Worst - Incorporate individuals into the population replacing the worst ones
SYNOPSIS
my $op = new Algorithm::Evolutionary::Op::Replace_Worst;
$op->apply( $old_population_hashref, $new_population_hashref );
Base Class
Algorithm::Evolutionary::Op::Base
DESCRIPTION
Attempts all possible mutations in order, until a "novelty" individual is found. Generated individuals are checked against the population hash, and discarded if they are already in the population.
METHODS
new()
Does nothing, really
apply( $population, $chromosome_list )
Eliminates the worst individuals in the population, replacing them by the list of new chromosomes. The population must be evaluated, but there's no need to have it sorted in advance.
SEE ALSO
Algorithm::Evolutionary::Op::Generation_Skeleton, where the replacement policy is one of the parameters
It can also be used in POE::Component::Algorithm::Evolutionary for insertion of new individuals asynchronously.
