Examples of jcgp.backend.population.Connection

jcgp.backend.population.Connection
{@code Connection} declares the expected behaviour of anypart of a chromosome that can be connected to, specifically nodes or inputs. Outputs are not connections since they mark the end of chromosome paths.

This interface provides a way to deal with connections generically without having to specify whether they are nodes or inputs. In this way a random connection can be picked and dealt with more easily, facilitating mutations. @author Eduardo Pedroni
