Graph clustering I: Cycles of cliques,ters. In general, it is NP-hard whether or not a graph is a two-level clustered graph of a particular type, e.g. a clique or a planar graph or a triangle of cliques. However, it is efficiently solvable whether or not a graph is a path of cliques or is a large cycle of cliques.作者: anus928 時(shí)間: 2025-3-25 15:48
