POJ 1724 ROADS

POJ_1724 这个题目可以直接将SPFA中的dis[]变成二维的dis[i][k]表示到第i个点花费为k时的最短路，但如果直接做SPFA会超时，需要加一个剪枝：设mind[i]表示到第i个点的用于剪枝最短路，mink[i] 表示第i个点的用于剪枝的最小花费，如果在SPFA的过程中走到了第i个点的路径长为d花费为k，那么如果d>=mind[i]&&k>=min

SGU 206 Roads

SGU_206 不得不说这个题目的思想太奇葩，一时间还是不能很理解…… 首先一个贪心的思路就是，石子路的d[i]一定是小于或等于c[i]的，而非石子路的d[j]是一定大于或等于c[j]的，如果我们用x[i]描述石子路谎报的增量那么有x[i]=c[i]-d[i]，用y[j]描述非石子路谎报的增量那么有y[j]=d[j]-c[j]，最后目标自然就是求sum{x[i]}+sum{y[j]
