Manual Reference Pages - ALGORITHM::EVOLUTIONARY::HASH_WHEEL (3)
Algorithm::Evolutionary::Hash_Wheel - Random selector of things depending on probabilities
my $wheel = new Algorithm::Evolutionary::Hash_Wheel( \%probs );
print $wheel->spin(); #Returns an element according to probabilities;
Creates a roulette wheel for spinning and selecting stuff. It will
be used in several places; mainly in the
Algorithm::Evolutionary::Op::CanonicalGA. Its similar to
Algorithm::Evolutionary::Wheel, but with a hash instead of an
array. Probably should unify both..
new( CW$probabilities_hashref )
Creates a new roulette wheel. Takes a hashref, which uses as keys the
objects to be returned by the roulette wheel, and as values the ones
that are going to be used
Returns a single individual whose probability is related to its fitness
TODO: should return many, probably
