NAME
Algorithm::Evolutionary::Op::Convergence_Terminator - Checks for termination of an algorithm, returns true if a certain percentage of the population is the sameSYNOPSIS
my $ct = new Algorithm::Evolutionary::Op::Convergence_Terminator 0.5;
do {
$generation->apply($pop_hashref );
} until ($ct->apply( $pop_hashref );
Base Class
Algorithm::Evolutionary::Op::BaseDESCRIPTION
Checks for termination after if population has convergedMETHODS
new( [$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 convergenceSee Also
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::EasyThere are other options for termination conditions: Algorithm::Evolutionary::Op::NoChangeTerm and Algorithm::Evolutionary::Op::DeltaTerm.
