Examples of jcgp.backend.population.Mutable

jcgp.backend.population.Mutable
{@code Mutable} declares the expected behaviour of anypart of a chromosome that is mutable, more specifically nodes or outputs. Inputs are not mutable since they don't have connections or functions.

This interface provides a way to deal with mutable elements generically without having to specify whether they are nodes or outputs. When mutating a mutable, {@code mutate()} is guaranteedto perform a fair mutation. @author Eduardo Pedroni
