Comparison with the cooperation diagrams of null models.
Average degree of cooperation 〈c〉 as a function of b (solid line with filled circles) for m = 3 (A), 6 (B), 10 (C) and 20 (D). In each panel we show the case of a simplex (m = 1) network, the evolution 〈c〉(b) for homogeneous strategists' populations corresponding to each value of m (Homo.) and the curve 〈c〉(b) corresponding to the mean-field assumption for the coupling between layers (M.F.). Each multiplex network has N = 250 nodes while the interdependent layers are ER graphs with 〈k〉 = 3.
