From: Surprise maximization reveals the community structure of complex networks

Two extreme networks designed to test the behavior of Surprise when small communities are present.
(a) A network with three communities (sizes 400, 13, 13). The nodes of the largest community have an average degree of 100, while the nodes in the two smallest communities form cliques. The three communities are interconnected by single links, as shown. (b) Cliques, each one with five nodes, which are connected also by single links in a way that can be depicted as a ring. The figure shows an example with eight cliques, but that number was progressively increased to determine whether the partition with highest S still corresponded to the one in which each cliques was an independent community.
