题目链接: http://poj.org/problem?id=1511 题目大意: 这道题目比较难理解,我读了好长时间,最后还是在队友的帮助下理解了题意,大意就是,以一为起点,求从一到其他各点的最短回路总和. 解题思路: 解决这个题目有几个容易错的,解决了离ac就不远了^_^. 1:数据范围是1<=边数<=顶点数<=1000000,所以不能用邻接矩阵,要用邻接表,用vector实现时要动态申请内存. 2:求得是起始点到其他点的最短回路和,我们可以建两个邻接表(一个正向,一个负向邻接表)…

昨天的题太水了,堆优化跑的不爽,今天换了一个题,1000000个点,1000000条边= = 试一试邻接表 写的过程中遇到了一些问题,由于习惯于把数据结构封装在 struct 里,结果 int [1000000] 导致 struct 爆栈,此问题亟待解决.. 实力碾压SPFA 2500 ms,有图为证 #include <cstdio> #include <cstdlib> #include <cstring> #include <algorithm> #d…

题意:学生从A站到B站花费C元,将学生每天从‘1’号站送往其它所有站,再从所有站接回到‘1’号站,问着个过程最小花费是多少. 思路:因为数据很大所以要用SPFA,因为不仅要从1点连接各个点还要从各个点返回一点,所以需要正邻接表和逆邻接表.然后正反各跑一次SPFA,值得注意的是因为数据很大,要将INF定位0xffffffff. #include<stdio.h> #include<string.h> #include<cstring> #include<string…
