Figure 1. Predicting epidemic threshold for uncorrelated configuration networks under different network sizes.

Theoretical predictions of (black solid lines), (red dashed lines), (blue dash-dotted lines) and numerical prediction (gray squares) versus network size N for degree exponent ν_D = 2.1 (a) and ν_D = 3.5 (b). The absolute errors between λ_c and (black solid lines), (red dashed lines) and (blue dash-dotted lines) versus N for ν_D = 2.1 (c) and ν_D = 3.5 (d).
