WebJan 9, 2024 · Dense subgraph discovery has proven useful in various applications of temporal networks. We focus on a special class of temporal networks whose nodes and edges are kept fixed, but edge weights regularly vary with timestamps. However, finding dense subgraphs in temporal networks is non-trivial, and its state of the art solution … WebWhile detecting dense subgraphs has been studied over static graphs, not much has been done to detect dense lasting subgraphs over dynamic networks. (1) Aggarwal et al. [4] propose a two-phase solution for ﬁnding frequently occurring dense subgraphs in dynamic graphs. In the ﬁrst phase, they identify vertices that tend to appear together ...
