"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. " - On the bottleneck shortest path problem
