http://codeforces.com/gym/101617/attachments 题意:给出一个图,每个顶点代表一个金矿,每个金矿有g和d两个值,g代表金矿初始的金子量,d是该金矿每天的金子量会减少d.顶点与顶点之间存在边,意思是从一个金矿到另一个金矿需要花费的天数.现在有个人一开始在1金矿,问最多能挖到多少金矿,注意,不能在一个金矿连续挖几天. 思路:bfs求解,但是需要剪枝,用二位数组d[v][day]记录第day天时在v金矿所能获得的最大值. #include<iostream>…

题目链接:http://codeforces.com/gym/100187/problem/E 题解:一开始做的时候是将两幅图合并,然后直接bfs看是否能到达终点.但这种做法的错的,因为走出来的路对于两幅图来说不一定都是最短的.正确做法: 第一步:分别用bfs求出两图的最短路. 第二步:如果最短路长度一样.则将两幅图合并,再bfs,如果能走到终点,且最短路长度仍然等于未合并前的长度,则YES: 否则NO. 学习之处: 求两个或多个事物所共有的东西,其实就是求交集. 代码如下: #include<…
