On the basis of the modularity concept, community detection can be modeled as a modularity optimization problem. The iterated greedy (IG) algorithm is a simple and effective meta-heuristic framework developed by Ruiz and Stutzle . After eliciting an …

Modularity is a scale value between −0.5 (non-modular clustering) and 1 (fully modular clustering) that …
Webgreedy approach to identify the community structure and maximize the modularity. msgvm is a greedy algorithm which performs more than one merge at one step and applies fast greedy refinement at the end of the algorithm to improve the modularity value. cd iteratively performs complete greedy refinement on a certain partition and then, moves ... WebGreedy Algorithm. 1. At the beginning, each node belongs to a different community; 2. The pair of nodes/communities that, joined, increase modularity the most, become part of …
WebJan 1, 2007 · In general, these modules are characterized by an abundance of edges connecting the vertices within individual communities in comparison to the number of edges linking the modules. To detect these... Webgreedy executes the general CNM algorithm and its modifications for modularity maximization. rgplus uses the randomized greedy approach to identify core groups (vertices which are always placed into the same community) and uses these core groups as initial partition for the randomized greedy approach to identify the community structure and …
