In this case, the detecting abilities of Fastgreedy, Infomap, Label propagation, Multilevel, Walktrap, Spinglass and Edge betweenness algorithms are independent of network size (Panel (a,b,d ), Fig. 5). For Leading eigenvector, the accuracies decrease smoothly with network size (Panel (c), Fig. 5).

Please notice that the vertical axis on the subfigures might have different scale ranges. The horizontal black dotted line corresponds to I = 1. Due to the computing speed, Spinglass and Edge betweenness algorithms have been tested only on networks with N 1000, and Infomap GS-4059 site algorithm has been tested on networks with N 22186.

The results are represented in Fig. 6 on a log-log scale. Each panel presents the computing time of a given community detection algorithms and is subdivided in two plots: one for the measured value of computing time in second and the upped sub-panel contains the standard deviation of the measures when repeated over different network realisations.
