CommunityStructureAssignment

As of Version 10, all the functionality of the GraphUtilities package is built into the Wolfram System. »

CommunityStructureAssignment[g]

gives the assignment of vertices of a graph g into communities.

Details and Options

  • CommunityStructureAssignment functionality is now available in the built-in Wolfram Language function FindGraphCommunities.
  • To use CommunityStructureAssignment, you first need to load the Graph Utilities Package using Needs["GraphUtilities`"].
  • The assignment groups the vertices into communities, such that there is a higher density of edges within communities than between them.
  • The following option can be given:
  • Weighted Falsewhether edges with higher weights are preferred during matching
