ZOJ 1314 Reactor Cooling | 上下界无源汇可行流 题意 有一个网络,每条边有流量的上界和下界,求一种方案,让里面的流可以循环往复地流动起来. 题解 上下界无源汇可行流的模型: 设置虚拟源点和虚拟汇点. 如果一条边\(u \to v\)的下界是\(mi\).上界是\(ma\),则在图中建一条\(u \to v\)的边,流量是\(ma - mi\),同时记录\(oud[u] += mi, ind[v] += mi\),分别代表\(u\)实际比图上多流出的流量与\(v\)实际比

时间限制:0.5s 空间限制:6M 题意: 显然就是求一个无源汇有上下界的网络流的可行流的问题 Solution: 没什么好说的,直接判定可行流,输出就好了 code /* 无汇源有上下界的网络流 */ #include <iostream> #include <cstring> #define ms(a,b) memset(a,b,sizeof a) using namespace std; ; struct node { int u, v, c, ne; } edge[MAXN

[题目分析] 无源汇上下界可行流. 上下界网络流的问题可以参考这里.↓ http://www.cnblogs.com/kane0526/archive/2013/04/05/3001108.html [代码] #include <cstdio> #include <cstring> #include <cmath> #include <cstdlib> //#include <map> #include <set> #include

前言 话说有上下界的网络流好像全机房就我一个人会手动滑稽,当然这是不可能的 Solution 其实这道题目就是一道板子题,主要讲解一下怎么做无源无汇的上下界最大流: 算法步骤 1.将每条边转换成0~up-down. 但是,我们发现转换的时候不能保证一定是流量守恒. 2.可以把一条边的起点都减去下界,终点加上上界.令这个数组为\(d\) 3.对于\(d_i<0\),那么向汇点连条边:对于\(d_i>0\),从源点连边. 4.最后从源点到汇点跑一边Dinic就好了. 代码实现 #include&l
