Fast algorithms for core maximization on large graphs

WebMar 11, 2024 · The core number of vertices is a basic index depicting cohesiveness of a graph, and has been widely used in large-scale graph analytics. In this paper, we study the update of core numbers of vertices in dynamic graphs with edge insertions/deletions, which is known as the core maintenance problem. 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. news-sun highlands county https://adwtrucks.com
