Dynamic Shortest Path Algorithms for Hypergraphs by Jianhang Gao, Qing Zhao, Wei Ren, Ananthram Swami, Ram Ramanathan and Amotz Bar-Noy.

Abstract:

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.

The applicability of hypergraphs to “…social and communication networks…” should push this item to near the top of your reading list. In addition to the alphabet soup of various government agencies from around the world mining such networks are e-commerce and traditional vendors. Developing solutions and/or having the skills to mine such networks should make you a hot-ticket item.
