"WebAnswer: A flow network is directed graph, in which each edge is assigned a capacity. We define a “flow” on such a graph by assigning a value to each edge such that: * The flow on each edge is at least zero, and less that that edge’s capacity. * Other than specifically identified source and sin...

Webof graph theory—and through it, networks—we will ﬁrst begin with some terminology. First of all, we deﬁne a graph G = (V,E) to be a set of vertices V = {v1,v2,...,v m} and a set … WebOct 27, 2016 · 2. The "capacity" of a cut is used as an upper bound on the flow from the source to the sink. The "capacity" of the cut is therefore equal to maximal flow that can cross the cut from the source to the sink. For this graph, that is at most 26. If you would subtract the backward edges, you no longer have an upper bound (you could even end …
