NAME

Algorithm::Evolutionary::Op::Tournament_Selection - Tournament selector, takes individuals from one population and puts them into another

SYNOPSIS

  my $popSize = 100;
  my $tournamentSize = 7;
  my $selector = new Algorithm::Evolutionary::Op::Tournament_Selection $tournamentSize;
  my @newPop = $selector->apply( @pop ); #Creates a new population from old

Base Class

Algorithm::Evolutionary::Op::Selector

DESCRIPTION

One of the possible selectors used for selecting the pool of individuals that are going to be the parents of the following generation. Takes a set of individuals randomly out of the population, and select the best.

METHODS

new( $output_population_size, $tournament_size )

Creates a new tournament selector

apply( $ref_to_population[, $output_size || @$ref_to_population] )

Applies the tournament selection to a population, returning another of the same size by default or whatever size is selected. Please bear in mind that, unlike other selectors, this one uses a reference to population instead of a population array.

Algorithm::Evolutionary::Op::RouleteWheel is another option for selecting a pool of individuals
