  1. Runs are divided into three types based on the highest level of communication that emerged (“none” in the case of one run where communication never emerged and 10 additional runs with ωin = 0 for all t). The average (μ), standard deviation (σ), and two-tailed Wilcoxon rank-sum test P values are shown.
