Figure 4

Numerical simulations on the case of fully connected networks with size N = 10³, where the “triangles” and “circles” represent the forward and backward processes, respectively. (a–d) Show the dependence of r on κ for 〈τ〉/2π = 0.16 and different σ, respectively, with (a) σ = 0.001; (b) σ = 0.01; (c) σ = 0.1; and (d) σ = 1.0.
