WebThe shortest path problem is about finding a path between $$2$$ vertices in a graph such that the total sum of the edges weights is minimum. This problem could be solved easily using (BFS) if all edge weights were ($$1$$), but here weights can take any value. Three different algorithms are discussed below depending on the use-case. WebApr 15, 2016 · Obviously you can run the "shortest distance" algorithm six times. You'd want to do better than that. I'd start by ordering the six permutations of (B, C, D) according to the length of the straight line connection. Let's say the straight line connection A->C->D->B->E is shortest. You find the shortest route from A to C, C to D, D to B, B to E.
