WebProblem 16.3 (Single-Source Shortest Paths (SSSP)). Given a weighted graph G= (V;E;w) and a source vertex s, the single-source shortest path (SSSP) problem is to ﬁnd a shortest weighted path from sto every other vertex in V. Although there can be many equal weight shortest paths between two vertices, the problem only requires ﬁnding one.
