WebThe weights of the edges. It must be a positive numeric vector, NULL or NA. If it is NULL and the input graph has a ‘weight’ edge attribute, then that attribute will be used. If NULL and no such attribute is present, then the edges will have equal weights. Set this to NA if the graph was a ‘weight’ edge attribute, but you don't want to ... WebMar 18, 2024 · The Louvain algorithm was proposed in 2008. The method consists of repeated application of two steps. The first step is a “greedy” assignment of nodes to communities, favoring local optimizations of modularity. The second step is the definition of a new coarse-grained network based on the communities found in the first step.

"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).
