Web4 Mar 2024 · The Louvain Community Detection method, developed by Blondel et al. (2008), is a simple algorithm that can quickly find clusters with high modularity in large networks. … WebLouvain maximizes a modularity score for each community. The algorithm optimises the modularity in two elementary phases: (1) local moving of nodes; (2) aggregation of the network. In the local moving phase, individual nodes are moved to the community that yields the largest increase in the quality function.
