Algorithm::Evolutionary::Op::Replace_Worst - Incorporate individuals into the population replacing the worst ones
my $op = new Algorithm::Evolutionary::Op::Replace_Worst;
$op->apply( $old_population_hashref, $new_population_hashref );
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.
Does nothing, really
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.
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.
