<S extends T> List<S> select(List<EvaluatedCandidate<S>> population, boolean naturalFitnessScores, int selectionSize, Random rng)
Select the specified number of candidates from the population. Implementations may assume that the population is sorted in descending order according to fitness (so the fittest individual is the first item in the list).
It is an error to call this method with an empty or null population.

- The type of evolved entity that we are selecting, a sub-type of T.population
- The population from which to select.naturalFitnessScores
- Whether higher fitness values represent fitter
individuals or not.selectionSize
- The number of individual selections to make (not necessarily
the number of distinct candidates to select, since the same individual may
potentially be selected more than once).rng
- Source of randomness for stochastic selection strategies.
