cross edges? 6. 有n个nodes的graph可以有多少切分方式? 7. 什么是minimum cut problem? 8. graph partition有什么使用场景? 其实感觉有点像聚类
Using rigorous runtime analyses we show how the ACO algorithm behaves similarly to Karger and Stein's algorithm for the minimum cut problem as long as the use of pheromone values is limited. Hence optimal solutions are obtained in expected polynomial time. On the other hand, we show that ...
所以就计算每条非树边对树边的影响 这些树边也就是非树边两端点在树上确定的那条路径上的边 考虑树剖链更新 但是会T 可以发现更新和查询是分开的 所以利用差分数组的思想 对两点++ 对两点的lca-=2 然后后序遍历一遍 每个点把所有子节点的值都拿上来 最后扫一遍数组就可以了 #include <bits/stdc++.h> usin...
The connection between the minimum-cut problem in a capacitated network and certain combinatorial problems is well-known. This article presents and analyzes a selection problem in the context of a cooperative game, with emphasis on the key role of associated minimum-cut problems. Each coalition sele...

A new approach to the minimum cut problem 来自 Semantic Scholar 喜欢 0 阅读量: 39 作者:D Karger,C Stein 摘要: This paper present a new approach to finding minimum cuts in undirected graphs. The fundamental principle is simple: the edges in a graph's minimum cut form an extremely small ...
http://poj.org/problem?id=2914 题意:给出n个点m条边,可能有重边,问全局的最小割是多少。 思路:一开始以为用最大流算法跑一下,然后就超时了。后来学习了一下这个算法,是个模板题。具体学习可以参考: http://blog.sina.com.cn/s/blog_700906660100v7vb.html ...
(capacity) vector c to d so that x0is an optimal solution of P with respect to the cost (capacity) vector d, and to minimize some objective function. In this paper, we consider the weighted inverse minimum cut problem under the bottleneck type Hamming distance. For the general case, we...

The present work tackles a new problem of this class: the k-cardinality minimum cut problem (k-card cut). For a number of variants of this problem we show complexity results in the most significant graph classes. Moreover, we develop several heuristic algorithms for the k-card cut problem ...
