The simulated beefs genome consists of a string of 28 genes, each representing a parameter governing the network architecture or learning dynamics. ... The regular and differential
modules each have a different learning rule specified
by four real-valued genes (parameters A . D of
Equation 3, initialized in range [.0.2, 0.2]); The global
learning rate of the network ā is specified by a realvalued
gene (initialized in range [0, 1]); and four
