Given a weighted, directed graph G = (V, E) with no negative-weight cycles, let m be the maximum over all pairs of vertices u, v ¬ V of the minimum number of edges in a shortest path from u to v. (Here, the shortest path is by weight, not the number of edges.) Suggest a simple change to the Bellman-Ford algorithm that allows it to terminate in m + 1 passes.
Answer to relevant QuestionsThe PERT chart formulation given above is somewhat unnatural. It would be more natural for vertices to represent jobs and edges to represent sequencing constraints; that is, edge (u, v) would indicate that job u must be ...Why are pseudo variable logically unnecessary?We pointed out that it is strictly incorrect to say that (e.g.) the quantity for a certain shipment is 100 (“a quantity is a value of type QTY, not a value of type INTEGER”).
