WebParallel Core Maintenance of Dynamic Graphs. Abstract: A -core is the special cohesive subgraph where each vertex has at least degree. It is widely used in graph mining applications such as community detection, visualization, and clique discovery. Because dynamic graphs frequently evolve, obtaining their -cores via decomposition is inefficient.
WebJun 22, 2024 · As a fundamental problem in graph analysis, core decomposition aims to compute the core numbers of vertices in a given graph. It is a powerful tool for mining important graph structures. For dynamic graphs with real-time updates of vertices/edges, core maintenance has been utilized to update the core numbers of vertices.
