"WebSep 21, 2024 · Description: Fastgreedy community detection is a bottom-up hierarchical approach. It tries to optimize function modularity function in greedy manner. Initially, every node belongs to a separate community, and communities are merged iteratively such that each merge is locally optimal (i.e. has high increase in modularity value).
