Figure 5. Results for Erdös-Rényi random graphs.

Figure 5

(a) The bifurcation lines and cusp point in parameter space obtained through simulations of Erdös-Rényi random graphs of size Inline graphic with different average degrees. The mean-field analytical curve is shown for comparison. For simulation results, the bifurcation curves are obtained by identifying the critical points that lie on linear trajectories described by Inline graphic in parameter space. This process is carried out for different values of Inline graphic between Inline graphic and Inline graphic at intervals of Inline graphic, and for each value of Inline graphic, Inline graphic is varied at a resolution of Inline graphic. For each such combination of Inline graphic obtained, we perform averages for quantities of interest over Inline graphic realizations of networks (with a single realization of the social influence dynamics per network), for each of two initial conditions, Inline graphic and Inline graphic with Inline graphic in each case. (b)–(c) Steady-state magnetization for ER graphs with Inline graphic and different sizes Inline graphic, as parameter pair values are varied successively along slope Inline graphic and slope Inline graphic lines in parameter space respectively.
