  • Goal-seeking networks comprised two previously identified hill climbing motifs (Figs. 35), one for movement up the gradient (rows) and one for movement down the gradient (columns). Frequencies are based on a sample of 59 networks. ID, interneuron differentiator; SND, sensory neuron differentiator; BT, bounce-and-trap; and —, formally impossible motif combination (see text).
