WebCommunity structure via greedy optimization of modularity Description This function tries to find dense subgraph, also called communities in graphs via directly optimizing a modularity score. Usage cluster_fast_greedy ( graph, merges = TRUE, modularity = TRUE, membership = TRUE, weights = NULL ) Arguments Details WebModularity Algorithm #1 • Modularity is NP-hard to optimize (Brandes, 2007) • Greedy Heuristic: (Newman, 2003)-C = trivial clustering with each node in its own cluster-Repeat: • Merge the two clusters that will increase the modularity by the largest amount • Stop when all merges would reduce the modularity.
