最大流最小割 Introduction Mincut Problem 最小割问题,输入是带权有向图,有一个源点 s(source)和一个汇点 t(target),边的权重在这里称作容量(capacity),是个正数. st-cut(cut): 把图的点分成两个集合 A 和 B,源点 s 和汇点 t 分别属于集合 A 和 B. capacity: 从集合 A 的点指向集合 B 的点的边的权重之和,如下图. 最小割问题就是找到使 capacity 最小的划分(st-cut),即阻隔从源点到汇点的最小…
Naive solution for this problem would be caluclate all the possible combinations: const numbers = [1, -3, 2 - 5, 7, 6, -1, -4, 11, -23]; // O(n^3) const findMaxSubAry = numbers => { let answer = Number.MIN_VALUE; /** * Calculate all the possible valu…
题意:一张有n个点的图,结点被编号为0~n-1,i往所有编号比它大的点j连边,权值为i xor j.给你n,问你最大流. 打个表,别忘了把相邻两项的差打出来,你会发现神奇的规律……你会发现每个答案都是由某些特定的数加起来组成的,最好把它们也打出来. #include<cstdio> using namespace std; typedef long long ll; #define MOD 1000000007ll ll n; int main(){ // freopen("e.ou…
