NAME

Algorithm::Evolutionary::Hash_Wheel - Random selector of things depending on probabilities

SYNOPSIS

    my $wheel = new Algorithm::Evolutionary::Hash_Wheel( \%probs );
    print $wheel->spin(); #Returns an element according to probabilities;

DESCRIPTION

Creates a "roulette wheel" for spinning and selecting stuff. It will be used in several places; mainly in the Algorithm::Evolutionary::Op::CanonicalGA. It's similar to Algorithm::Evolutionary::Wheel, but with a hash instead of an array. Probably should unify both..

METHODS

new( @probabilites )

Creates a new roulette wheel. Takes an array of numbers, which need not be normalized

spin()

Returns an individual whose probability is related to its fitness
