Benchmarking Evolutionary Community Detection Algorithms in Dynamic Networks

no code implementations21 Dec 2023 Giordano Paoletti, Luca Gioacchini, Marco Mellia, Luca Vassio, Jussara M. Almeida

Nevertheless, addressing CD in dynamic graphs remains an open problem, since the evolution of the network connections may poison the identification of communities, which may be evolving at a slower pace.
