... footnote.1
All simulations used the quasi-stationary monte-carlo mode. For evolutionary fitness evaluations, where speed is important, a somewhat noisy simulation was used, with 3000 events simulated per timestep of 5ns. For Figs. 5, 6, 9 and 10, higher resolution tests were performed, using 10000 events per 0.5ns timestep. The nodes always had zero initial charge, and a different random-number seed was supplied to the simulator for each fitness trial.
