WebSee Answer. Question: 2. Figure 7.26 shows a flow network on which an s-t flow has been computed. The capacity of each edge appears as a label next to the edge, and the numbers in boxes give the amount of flow sent on each edge. (Edges without boxed numbers-specifically, the four edges of capacity 3-have no flow being sent on them.)

WebLet G be an arbitrary flow network, with a source s, and sink t, and a positive integer capacity c e on every edge e. 1) If f is a maximum s-t flow in G, then f saturates every edge out of s with flow (i.e., for all edges e out of s, we have f(e) = c e). 2) Let (A,B) be a minimum s-t cut with respect to these capacities .

WebThe maximum flow problem can be seen as a special case of more complex network flow problems, such as the circulation problem. The maximum value of an s-t flow (i.e., flow from source s to sink t) is equal to the minimum capacity of an s-t cut (i.e., cut severing s from t) in the network, as stated in the max-flow min-cut theorem. WebDeﬁnition 16.1 An s-t cut is a set of edges whose removal disconnects t from s. Or, formally, a cut is a partition of the vertex set into two pieces A and B where s ∈ A and t ∈ B. (The edges of the cut are then all edges going from A to B). Deﬁnition 16.2 The capacity of a cut (A,B) is the sum of capacities of edges in the cut. Or,
