Global Min-Cut ProblemAhuja, PuneetTelikepalli, Kavitha
The all-pairs min cut (APMC) problem on a nonnegative edge-weighted graph is to find, for each pair of nodes, a min cut that separates the pair. Gomory and Hu (1961) presented a structural characterization of collections of cuts that solve the APMC problem. We show how the APMC problem...
(https://ac.nowcoder.com/acm/problem/19887) 题目描述 A,B两个国家正在交战,其中A国的物资运输网中有N个中转站,M条单向道路。设其中第i (1 ≤ i ≤ M)条道路连接了vi,ui两个中转站,那么中转站vi可以通过该道路到达ui中转站,如果切断这条道路,需要代价ci。现在B国想找出一个路径切断方案,使中转站s不...
数学中的“min”概念还扩展到了如最小最大问题(min-max problem)和最小切割问题(min-cut problem)等,这些在算法和数据结构中极为重要,常用于解决各种计算问题。在编程语言中,“min”通常用来寻找数组或列表中的最小值。以Python编程语言为例,可以使用内置的“min”函数来找出列表中的最小元素。

It is known that if the edge weights are non-negative, then the min-cut problem is polynomially solvable, while the max-cut problem is NP-hard. We construct a partition of the positive orthant into convex cones corresponding to the characteristic cut vectors, similar to a normal fan of a ...
从这里可以看出来如果解决了min-ratio cut problem,i.e. minΔ∈RV⟨g,Δ⟩‖UBΔ‖1 ,我们就能让势函数减小! 当势函数比较小的时候 F−⟨d,y⟩ 就会很小 记得我们之前说过optimal solution一定形如 Δ=±1C ,也就是 minC⊆V⟨g,1C⟩‖UB1C‖1=minΔ∈RV⟨g,Δ⟩‖UBΔ‖1 ...
Algorithms for the all-pairs min-cut problem in bounded tree-width and sparse networks are presented. The approach used is to preprocess the input network so that, afterwards, the value of a min-cut between any two vertices can be efficiently computed. A tradeoff between the preprocessing time...
The minimum cut problem asks for the s-t cut with minimalc(S,T)c(S,T). What's the main theorem? The main theorem links maximum flow through a network with the minimum cut of the network. The maximum value of an s-t flow is equal to the minimum capacity over all s-t cuts. ...
