On weakly optimal partitions in modular networks cs.SI cond-mat.stat-mech physics.soc-ph Modularity was introduced as a measure of goodness for the community structure induced by a partition of the set of vertices in a graph. Then, it also became an objective function used to find good partitions, with high success...
