Overview

Neuron – Basis of all Neat Neuron types.

Normally contains primatives which aids in its own expression, but the details of this remains to be worked out.

#heirarchy_number ⇒ Object

(assigned by wire!) Heirarchy number in the Genome / Critter We need this to assure we add genes in the proper order. This will be recalculated every time a new neuron is added.

Instance Method Details

#bias? ⇒ Boolean

Returns:

  • (Boolean)

# File 'lib/rubyneat/neuron.rb', line 44

def bias? ; self.class.bias? ; end

#express(instance) ⇒ Object

Function must be implemented by subclasses for phenotype generation. Basically, an instance is passed to this function and it will add a function to sum all inputs and a apply an operator to the sum.
