[hdu P1599] find the mincost route 杭州有N个景区,景区之间有一些双向的路来连接,现在8600想找一条旅游路线,这个路线从A点出发并且最后回到A点,假设经过的路线为V1,V2,....VK,V1,那么必须满足K>2,就是说至除了出发点以外至少要经过2个其他不同的景区,而且不能重复经过同一个景区.现在8600需要你帮他找一条这样的路线,并且花费越少越好.  Input第一行是2个整数N和M(N <= 100, M <= 1000),代表景区的个数和道路的条…

[题目链接] 点击打开链接 [算法] 弗洛伊德求最小环模板 我们知道,在一个环上,一定有一个有且仅有一个编号最大的点,设这个点为k,起点为i,终点为j,那么 mincost = dist[i][j] + cost[j][k] + cost[k][i] (dist[i][j]为i到j的最短路) 所以只需枚举i,j,k,在计算最短路的同时,计算最小环,即可 [代码] #include<bits/stdc++.h> using namespace std; #define MAXN 110 cons…
