Figure 3

Modularity of community structures obtained at different γ values calculated using NG and our new modularity function of Eq. (3). Our function gives highest value at γ = 0.0004 (Fig. 2h, the right solution) whereas NG modularity has highest value at γ = 0.005 (Fig. 2e), clearly not the most optimal solution). The secondary x-axis represents indices of the subplots in Fig. 2.
