Webshortest paths from that single vertex to all other vertices in the graph. The shortest-path part means that we want to find the paths with the smallest aggregate cost. There is a … Web• As with unweighted graphs: – δ(s, t) = ∞ if no path from s to t – Subpaths of shortest paths are shortest paths (or else could splice in a shorter path) • Why infimum not minimum? Possible that no finite-length minimum-weight path exists • When? Can occur if there is a negative-weight cycle in the graph, Ex: (b, f, g, c, b) in G
