NAME

Algorithm::Evolutionary::Op::Replace_Different - Incorporate individuals into the population replacing the worst ones but only if they are different.

SYNOPSIS

  my $op = new Algorithm::Evolutionary::Op::Replace_Different; 
  $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

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.
