This example shows the detection of communities in the Zachary Karate Club dataset using the Girvan-Newman method. We plot the change in modularity as important edges are removed. Graph is coloured and plotted based on community detection when number of iterations are 1 and 4 respectively.

WebThe Girvan–Newman algorithm detects communities by progressively removing edges from the original graph. The algorithm removes the “most valuable” edge, traditionally the edge with the highest betweenness centrality, at each step. WebApr 6, 2024 · The Girvan-Newman algorithm can be divided into four main steps: For every edge in a graph, calculate the edge betweenness centrality. Remove the edge with the highest betweenness centrality. Calculate the betweenness centrality for every remaining edge. Repeat steps 2–4 until there are no more edges left. play games on pc earn money
