Fig. 6From: Replicator equation on networks with degree regular communitiesCoordination game, imitation. The graph has three communities, respectively of degree k=3, k=4, k=5, colours represent the position in the probability simplex above, hence the triple (P3,P4,P5) reporting the probability a node is in each of the three communities. The coloured surface represents the separation between the basins of attraction, where the volume above the surface is the basin of A and that below is the basin of B. The light-blue plane is the set of points where the two basins are equal. Similar to birth-death, also for imitation the basin of attraction of A can be larger than that of B for a close to 3, so also imitation may promote Pareto-efficiency over risk-dominance, but less than birth-death, as can be seen comparing the volumes below the light-blue plane in the two casesBack to article page
