Figure 3

Phase diagrams for officers (upper panel) and citizens (lower panel) for increasing CN with parameters NO = 100, NC = 100, ON = 2, IN = 1, r = b with (a) CN = 4, (b) CN = 6 and (c) CN = 50. Other fixed parameters are v = 1, c = 1, po = 2, pc = 0. Increasing the degree of the citizen network initially favours fixation of honest officers over a larger area of phase space but subsequent increase is detrimental to their dominance in the population.
