WebThe game's "shortest path" tends to pick the same Platform for all traffic coming in on the same tracks, and paths are fully static so they didn't adjust to changing conditions. The cue problem could be solved with manual Platform assignment but if things got out of phase it could still back up a bit. It does mostly fix the delays. Web14 de jul. de 1992 · A complete edge-weighted directed graph on vertices 1,2,...,n that assigns cost c (i,j) to the edge (i,j) is called Monge if its edge costs form a Monge array, i.e., for all i < k and j < l, c [i, j]+c [k,l] {le} < c [i,l]+c [k,j]. One reason Monge graphs are interesting is that shortest paths can be computed quite quickly in such graphs.
