超图的动态最短路算法

Dynamic Shortest Path Algorithms for Hypergraphs

Jianhang Gao, Qing Zhao, Wei Ren, Ananthram Swami, Ram Ramanathan, Amotz Bar-Noy

摘要:

超图是顶点的集合V和V的非空子集的集合,称为超边。与图不同,超图可以捕捉社交和通信网络中的高阶交互,而不仅仅是两两关系的简单结合。本文研究超图中的最短路问题。我们开发了两个算法,在一个动态网络的重量和拓扑变化的最短超路径的发现和维护。这两个算法是第一个解决一般超图中全动态最短路问题的算法。它们通过基于变化动态的性质和超图的类型划分应用程序空间来相互补充。

英文摘要:

A hypergraph is a set V of vertices and a set of non-empty subsets of V, called hyperedges. Unlike graphs, hypergraphs can capture higher-order interactions in social and communication networks that go beyond a simple union of pairwise relationships. In this paper, we consider the shortest path problem in hypergraphs. We develop two algorithms for finding and maintaining the shortest hyperpaths in a dynamic network with both weight and topological changes. These two algorithms are the first to address the fully dynamic shortest path problem in a general hypergraph. They complement each other by partitioning the application space based on the nature of the change dynamics and the type of the hypergraph.
