NAME

Algorithm::Evolutionary::Op::Convergence_Terminator - Checks for termination of an algorithm, returns true if a certain percentage of the population is the same

SYNOPSIS

my $ct = new Algorithm::Evolutionary::Op::Convergence_Terminator 0.5; 
do {
  $generation->apply($pop_hashref );
} until ($ct->apply( $pop_hashref );

Base Class

Algorithm::Evolutionary::Op::Base

DESCRIPTION

Checks for termination after if population has converged

METHODS

new( [$population_proportion = 0.5] )

Creates a new generational terminator:

my $ct = new Algorithm::Evolutionary::Op::Convergence_Terminator 0.5; 

will make the apply method return false after if 50% of the population are the same, that is, its "genetic" representation is equal.

apply()

Checks for population convergence

Algorithm::Evolutionary::Op::FullAlgorithm needs an object of this class to check for the termination condition. It's normally used alongside "generation-type" objects such as Algorithm::Evolutionary::Op::Easy

There are other options for termination conditions: Algorithm::Evolutionary::Op::NoChangeTerm and Algorithm::Evolutionary::Op::DeltaTerm.
