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. Webboring nodes to communities and then combining communities into a single node. The algorithm is deﬁned as follows: Initialize all nodes to be in its own community, for a total of n communities. Also, initialize all edge weights to 1. Then, repeat the following 2 steps: 1. Modularity Optimization Repeat the following process

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 Webwe evaluate the greedy algorithm of modularity max-imization (denoted as Greedy Q), Fine-tuned Q, and Fine-tuned Qds by using seven community quality metrics based on ground truth communities.
