WebMay 14, 2024 · In this paper, we study hierarchical core maintenance which is to compute the k-core hierarchy incrementally against graph dynamics. The problem is challenging because the change of hierarchy may be large and complex even for a slight graph update. In order to precisely locate the area affected by graph dynamics, we conduct in-depth … WebOct 26, 2024 · Zhang et al. proposed a fast order-based approach for the core maintenance that outperformed the state-of-the-art algorithms.

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

WebIn static graphs, the core decomposition problem has been extensively studied [4], [6], [9], [11]. In contrast, researches on core maintenance in dynamic graphs are fewer. All previous works focus on the case of single edge update, and sequen-tially handle multiple edge updates. Efficient algorithms were proposed in [10], [12].
