http://acm.hdu.edu.cn/showproblem.php?pid=1026 题意:给出一个迷宫,求出到终点的最短时间路径. 这道题目在迷宫上有怪物,不同HP的怪物会损耗不同的时间,这个时候可以用优先队列,每次让时间最短的出队列.由于最后还需要输出路径,所以需要设置一个数组来保存路径. #include<iostream> #include<queue> #include<cstring> using namespace std; + ; struct…

以前写的题了,现在想整理一下,就挂出来了. 题意比较明确,给一张n*m的地图,从左上角(0, 0)走到右下角(n-1, m-1). 'X'为墙,'.'为路,数字为怪物.墙不能走,路花1s经过,怪物需要花费1s+数字大小的时间. 比较麻烦的是需要记录路径.还要记录是在走路还是在打怪. 因为求最短路,所以可以使用bfs. 因为进过每一个点花费时间不同,所以可以使用优先队列. 因为需要记录路径,所以需要开一个数组,来记录经过节点的父节点.当然,记录方法不止一种. 上代码—— #include <cst…

这个问题是一个典型的类型的问题迷宫广泛的搜索. 在网上看到了很多解决方案. 没什么解决问题的分析报告,不指出其中的关键点.代码更像是一大抄.一些分析师也有很大的文章分析.只是不要全部命中关键,什么是广泛而深刻的,甚至搜索发现,在分析差异.为什么快速搜索宽像,什么样的风暴喊搜索,都错了.代码都是抄过的. 通过一大段的时间研究,最终搞通了. 本题尽管能够说是广搜.可是当中的关键却是剪枝法.为什么呢? 由于迷宫并不能简单地广搜就能搜索出全部路径的,甚至仅仅要迷宫大点就不能搜索出是否有路径.假设没有条件…

题目链接:hdu 1028 Ignatius and the Princess III 题意:对于给定的n,问有多少种组成方式 思路:dp[i][j],i表示要求的数,j表示组成i的最大值,最后答案是dp[i][i].那么dp[i][j]=dp[i][j-1]+dp[i-j][i-j],dp[i][j-1]是累加1到j-1的结果,dp[i-j][i-j]表示的就是最大为j,然后i-j有多少种表达方式啦.因为i-j可能大于j,这与我们定义的j为最大值矛盾,所以要去掉大于j的那些值 /*******…
