Heuristic Modularity Maximization Algorithms for Community Detection Rarely Return an Optimal Partition or Anything Similar

no code implementations28 Feb 2023 Samin Aref, Mahdi Mostajabdaveh, Hriday Chheda

Additionally, results on adjusted mutual information reveal substantial dissimilarity between the sub-optimal partitions and any optimal partition of the networks in our experiments.
