Overview

Gene Specification

The Gene specifies a singular input and output neuron, which represents a connection between them, along with the weight of that connection, which may be positive, negative, or zero.

There is also the enabled flag

Class Method Details

.[](genotype, input, output, weight = 0.0, innov = nil) ⇒ Object

Create a new Gene and set it up fully. genotype – genotype input – name of input neuron connection output – name of output neuron connection weight – weight to give neuron (optional) innov – innovation number of gene (optional)
