Flowchart of the algorithm. Trial subnetworks are constructed and tested against the best available subnetwork in an iterative manner. For the examples presented herein, $I_1^{max}$ and $I_2^{max}$ were set to 3 and 100, respectively. The error threshold function was defined as E_thr(I₁) = E_thr0/I₁ where E_thr0 was set to 10^–3. The value of α for the fitness function was set to 0.035. See the main text for definitions of fitness and error functions, F and E, respectively.
