All Implemented Interfaces:

EvolutionaryOperator

public class NEATMutateRemoveLink
extends NEATMutation

Mutate a genome by removing a random link. Do not remove links from genomes that have fewer than 5 links. ----------------------------------------------------------------------------- http://www.cs.ucf.edu/~kstanley/ Encog's NEAT implementation was drawn from the following three Journal Articles.
