WebWe now show how we obtain the hardness result for undirected graphs. If we simply make all edges undirected, the instance is not necessarily hard since the ﬂows may travel along reverse directions. Given an undirected graph Gobtained from the above instance by removing directions, we describe a simple trick that makes all capacity-1 edges (the Web15 sep. 2024 · The 3 graphs are {1-2, 3}, {2-3, 1}, {1-3, 2}.
