The Louvain method for community detection is a method to extract non-overlapping communities from large networks created by Blondel et al.^[1] from the University of Louvain (the source of this method's name). The method is a greedy optimization method that appears to run in time ${\displaystyle O(n\cdot \log n)}$ where ${\displaystyle n}$ is the number of nodes in the network.^[2]
