Methods in ec that return Population

Modifier and Type	Method and Description
abstract Population	Breeder.breedPopulation(EvolutionState state) Breeds state.population, returning a new population.
abstract Population	Initializer.initialPopulation(EvolutionState state, int thread) Creates and returns a new initial population for the evolutionary run.
abstract Population	Exchanger.postBreedingExchangePopulation(EvolutionState state) Performs exchanges after the population has been bred but before it has been evaluated, once every generation (or pseudogeneration).
