WebApr 13, 2024 · In this article, we will cover the Girvan-Newman algorithm – an example of the divisive method. Girvan-Newman Algorithm for Community Detection. Under the Girvan-Newman algorithm, the communities in a graph are discovered by iteratively removing the edges of the graph, based on the edge betweenness centrality value. WebIt creates a Graph from the specified edges, automatically creating any vertices mentioned by edges. All vertex and edge attributes default to 1. The canonicalOrientation argument allows reorienting edges in the positive direction (srcId < dstId), which is required by the connected components algorithm. The minEdgePartitions argument specifies the …
