Greedy modularity communities

WebGreedy modularity maximization begins with each node in its own community and joins the pair of communities that most increases modularity until no such pair exists. This function maximizes the generalized modularity, where resolution is the resolution parameter, often expressed as γ . See modularity (). Parameters: GNetworkX graph 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 ...

The CNM algorithm uses the modularity to find the communities strcutures. At every step of the algorithm two communities that contribute maximum positive value to global modularity are merged. WebFinding the maximum modularity partition is computationally difficult, but luckily, some very good approximation methods exist. The NetworkX greedy_modularity_communities() function implements Clauset-Newman-Moore community detection. Each node begins as its own community. The two communities that most increase the modularity ...

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.
