Ford-Fulkerson algorithm is a greedy approach for calculating the maximum possible flow in a network or a graph. A term, flow network, is used to describe a network of vertices and edges with a source (S) and a sink (T). Each vertex, except S and T, can receive and send an equal amount of stuff through it.

Definition. A flow network is a directed graph G Æ (V,E) with distinguished vertices s (the source) and t (the sink), in which each edge (u,v) 2 E has a nonnegative capacity c(u,v). We require that E never contain both (u,v) and (v,u) for any pair of vertices u,v (so in particular, there are no loops).Applications of Max-Flow-Min-Cut.

In a network flow problem, we assign a flow to each edge. There are two ways of defining a flow: raw (or gross) flow and net flow. Raw flow is a function \(r(v,w)\) that satisfies the following properties: Conservation: The total flow entering \(v\) must equal the total flow leaving \(v\) for all verticles except \(s\) and \(t\).The network flow problem differs from our usual standard-form linear programming problem in two respects: (1) it is a minimization instead of a maximization and (2) the constraints are equalities instead of inequalities. Nonetheless, we have studied before how duality applies to problems in nonstandard form. 网络流. 在 圖論 中， 網絡流 （英語： Network flow ）是指在一個每條邊都有 容量 （Capacity）的 有向圖 分配 流 ，使一條邊的流量不會超過它的容量。. 通常在 运筹学 中，有向图称为网络。. 顶点 称为 节点 （Node）而边称为 弧 （Arc）。. 一道流必須符合一個結點 ...
