动态规划的解决方法是找到动态转移方程. 题目地址:http://acm.hdu.edu.cn/game/entry/problem/show.php?chapterid=3&sectionid=2&problemid=4 题目大意:找到一个最多的老鼠序列,使得序列中的老鼠的体重满足递增,相应老鼠的速度满足递 减.即可要求找出老鼠体重递增,速度递减的最长子序列(不需要连续). 思路:动态转移方程的确定,状态f[i]表示前i个老鼠中的最长递减子序列长度,状态转移方程为mouse[i].len…

题目大意:输入数据直到文件结束,每行两个数据 体重M 和 速度V,将其排列得到一个序列,要求为:体重越大 速度越低(相等则不符合条件).求这种序列最长的长度,并输出路径.答案不唯一,输出任意一种就好了. 题目思路:这是个最长上升子序列的问题,我们按W的升序进行排序,若W相等则按V的降序排序.用Pre[]记录当前点的前驱节点,Last记录序列最后一个点,maxn记录最长长度,完成动规后可根据Last和Pre[]输出路径. #include<cstdio> #include<stdio.h&…

HDU - 1160 给一些老鼠的体重和速度 要求对老鼠进行重排列,并找出一个最长的子序列,体重严格递增,速度严格递减 并输出一种方案 原题等于定义一个偏序关系 $(a,b)<(c.d)$ 当且仅当 $a<c,b>d$ 然后找出最长链 ...我们就按照他说的重新排个序,然后找LIS吧,不过还需要去路径还原 数据量可以用$O(n^2)$的算法 不过我这里用来$O(nlogn)$的算法加上一个路径还原 嗯,其实是在一个单调栈上乱搞的二分罢了.... 最后要回溯一下并且记录答案才行 #incl…
