Algorithm::Evolutionary::Wheel - Random selector of things depending on probabilities
my $wheel = new Algorithm::Evolutionary::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. Take care that fitness must be non-zero positives; since if they aren't, roulette wheel won't work at all
Creates a new roulette wheel. Takes an array of numbers, which need not be normalized
Returns an individual whose probability is related to its fitness
Returns the index of the first individual smaller than the item
