class NEAT::Critter::Genotype::Gene

Gene Specification¶ ↑

The Gene specifices a singlular 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

Attributes

enabled[RW]

Is this gene enabled?

genotype[RW]

parent genotype

in_neuron[RW]

input neuron's name (where our output goes) ouptut neuron's name (neuron to be queried)

innovation[RW]

innovation number

out_neuron[RW]

input neuron's name (where our output goes) ouptut neuron's name (neuron to be queried)

weight[RW]

weight of the connection

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)
