双塔DP+输出路径. 由于内存限制,DP只能开滚动数组来记录. 我的写法比较渣,但是POJ能AC,但是ZOJ依旧MLE,更加奇怪的是Uva上无论怎么改都是WA,其他人POJ过的交到Uva也是WA. #include<cstdio> #include<cstring> #include<cmath> #include<stack> #include<algorithm> using namespace std; ][+]; struct P { i…

poj  3311(状态压缩DP) 题意:一个人送披萨从原点出发,每次不超过10个地方,每个地方可以重复走,给出这些地方之间的时间,求送完披萨回到原点的最小时间. 解析:类似TSP问题,但是每个点可以重复走,先用floyd预处理每个点两两之间的最短距离,然后用状态压缩DP求出走完所有点后回到原点的最短距离,用一个二进制数表示城市是否走过. 状态表示:dp[i][j]表示到达j点状态为i的最短距离 状态转移方程:dp[i][j]=min(dp[i][j],dp[j'][k]+dis[k][j]),…
