而这个 st-cut 的容量等于跨切分流量,因为根据我们的构造原则,集合 A 到集合 B 的边不是饱和正向边就是空的反向边,flow-across计算式后半部分为零。再根据flow-value lemma有网络总流量等于跨切分流量,所以这个 st-cut 的容量等于网络总流量。 综上,三种情形是等价的。 3->2 即可说明 Ford-Fulkerson 方法可...
1) 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 function. 该算法将全变差去噪模型的能量函数最小化问题转化为图的最小割问题,然后采用图割技术(最大流/最小割算法)求得能量函数的...
Minimum Cost flow problem is a way of minimizing the cost required to deliver maximum amount of flow possible in the network. It can be said as an extension of maximum flow problem with an added constraint on cost(per unit flow) of flow for each edge. One other difference in min-cost ...

The maximum flow between vertices v_i and v_j in a graph G is exactly the weight of the smallest set of edges to disconnect G with v_i and v_j in different components (Ford and Fulkerson 1962; Skiena 1990, p. 178).
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...

1) maximum cost minimum flow 最小费用最大流问题 2) min-cost flow problem 最小费用流问题 1. We first construct an auxiliary network and convert themin-cost flow problemin origial network into the min-cost circulation problem in the auxilary network,and then find the optimal solution of min-...
We propose a novel and efficient heuristic algorithm for solving the distribution network reconfiguration problem for loss reduction. We formulate the problem of finding incremental branch exchanges as a minimum cost maximum flow (MCMF) problem. This novel approach finds the best set of concurrent bran...
