NAME

Algorithm::Evolutionary::Op::GenerationalTerm - Checks for termination of an algorithm.

SYNOPSIS

  my $gt = new Algorithm::Evolutionary::Op::GenerationalTerm 100; #apply will return false after 100 generations

Base Class

Algorithm::Evolutionary::Op::Base

DESCRIPTION

Checks for termination after a number of generations

METHODS

new( [$number_of_generations = 100] )

Creates a new generational terminator:

    my $gt = new Algorithm::Evolutionary::Op::GenerationalTerm 100; #apply will return false after 100 generations

will make the apply method return false after 100 calls

reset

Resets the number of generations to 0

apply()

Checks if the counter has arrived to the allotted number of generations, returns false when it does.

    $gt->apply(); 

will return false when it has been run for the number of times it has been initialized to

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, Algorithm::Evolutionary::Op::Convergence_Terminator and Algorithm::Evolutionary::Op::DeltaTerm.
