<p>(Top Left) desired topology. (Top Right) Fitness vs. Generations. (Bottom) 12 examples of parent (top) – offspring (bottom) pairs. The neuronal copying algorithm is capable of sustaining evolution by natural selection to optimize the topology of a 6-neuron topology motif. The desired topology is shown on the top left. The 12 pairs of graphs show the parent (top) and offspring (bottom) networks at 100-generation intervals. The initial topology was fully connected by weak weights. The blue line in the fitness graph shows the fitness of the parent, and the red dots show the fitness of the offspring. The relationship of the blue line to the red dots shows that fitness (as defined here) is heritable for most configurations.
