Greedy modularity communities

WebModularity optimization. The inspiration for this method of community detection is the optimization of modularity as the algorithm progresses. Modularity is a scale value between −0.5 (non-modular clustering) and 1 (fully modular clustering) that measures the relative density of edges inside communities with respect to edges outside communities. WebGreedy modularity maximization begins with each node in its own community and joins the pair of communities that most increases modularity until no such pair exists. This function maximizes the generalized modularity, where `resolution` is the resolution parameter, often expressed as $\gamma$.
