在一个图中 flows(流)和 cuts(割)有着非常多的联系,其终极体现就是 Max-flow min-cut theorem(最大流最小割定理)。我们在本小节会给出一些定义和性质,这些定义和性质一方面可以帮助我们设计求解最大流问题的算法,另一方面可以辅助证明出 Max-flow min-cut theorem(最大流最小割定理),让我们加深对 flows 和...

The famous max-flow min-cut theorem determines the maximum throughput of a network. 最大流最小割定理决定了网络的最大吞吐量。5) maximum flow/minimum cut 最大流/最小割 1. Then,some maximum flow/minimum cut algorithms could solve this problem,and get the global minimum of the TV energy ...
Maxflow-mincut Theorem def:Anet flowacross a cut(A,B) is the sum of flows from A to B minus the sum of flows from B to A. Flow-value Lemma:Let be any flow, and let (A,B) be any cut, thennet flow across (A,B) = value of ...

The max-flow min-cut theorem says that finding the minimum cut in a graph, is the same as finding the maximum flow, because the value of the minimum cut will be the same value as the maximum flow.Practical Implications of The Max-flow Min-cut Theorem...

In this tutorial, we’ll discuss how to find the minimum cut of a graph by calculating the graph’s maximum flow. We’ll describe the max-flow min-cut theorem and present an algorithm to find the maximum flow of a graph. Finally, we’ll demonstrate the algorithm with an example and an...
As to why this approach works we leave the proof to the reader (hint: show that the nodes i with d(i) > x and nodes j with d(j) < x engender a cut and use maximum-flow-minimum-cut theorem). Comparison of Improved and Unimproved versionsIn this section we identify the worst case...
