CPSC 490 Graph Theory: **Shortest** Path The **shortest** rob lem Consider the problem of finding the **shortest** path between nodes s and t in a graph (directed or undirected).

Finding the k **Shortest** Paths David Eppstei n ⁄ March 31,1997 Abstract We give algorithms for finding the k **shortest** paths (not required to be simple) connectinga pair of vertices in a digraph.
