Algorithm::Evolutionary::Op::Novelty_Mutation - Mutation guaranteeing new individual is not in the population
my $mmdp = new Algorithm::Evolutionary::Fitness::MMDP; my $bits = 36; my @population; for ( 1..100 ) { #Create and evaluate a population my $indi = new Algorithm::Evolutionary::Individual::BitString $bits; $indi->evaluate( $mmdp ); push @population, $indi; } my $nm = new Algorithm::Evolutionary::Op::Novelty_Mutation $mmdp->{'_cache'}; #Initialize using cache $nm->apply($population[$i]);
Algorithm::Evolutionary::Op::Base
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.
Creates a new mutation operator with an operator application rate (general for all ops), which defaults to 1, and stores the reference to population hash.
Applies mutation operator to a "Chromosome", a bitstring, really. Can be applied only to victims composed of [0,1] atoms, independently of representation; but it checks before application that the operand is of type BitString.
