Examples of communities detected with different methods. The different methods are the InfoMap method (IM, red), Louvain method (LV, blue) and Clique percolation method (CP, green). For each method, four examples are shown, with 5, 10, 20 and 30 nodes. The coloured links are part of the community, the grey nodes are the neighbors of the represented community. While IM and LV find almost tree-like structures, CP finds dense communities . Reproduced figure with permission from Tibély, G. et al., Phys Rev E 83(5):056125, 2011.
