Finding the k Shortest Paths
, 1997
"... We give algorithms for finding the k shortest paths (not required to be simple) connecting a pair of vertices in a digraph. Our algorithms output an implicit representation of these paths in a digraph with n vertices and m edges, in time O(m + n log n + k). We can also find the k shortest pat ..."

Dynamic Shortest Path Algorithms for Hypergraphs
"... A hypergraph is a set V of vertices and a set of nonempty subsets of V, called hyperedges. Unlike graphs, hypergraphs can capture higherorder interactions in social and communication networks that go beyond a simple union of pairwise relationships. In this paper, we consider the shortest path prob ..."
