For the majority of the students, it was the first problem they authored. Nevertheless, the result looks cute. A couple problems went to local contests. From the remaining ones, I composed two trainings and put them on Codeforces. The trainings are set at the following time: first:Dynamic ...
Hey Codeforces community! Today, let's dive deep into the fascinating world of Dynamic Programming (DP). Whether you're a beginner looking to grasp the basics or an experienced coder seeking advanced techniques, this guide aims to provide a comprehensive overview of DP concepts and applications. ...
对动态规划(Dynamic Programming)的理解:从穷举开始(转) 动态规划(Dynamic Programming,以下简称dp)是算法设计学习中的一道槛,适用范围广,但不易掌握。 笔者也是一直不能很好地掌握dp的法门,于是这个寒假我系统地按着LRJ的《算法竞赛入门经典》来学习算法,对dp有了一个比过往都更系统\更深入的理解,并在这里写出来与...
摘要:problem linkhttp://codeforces.com/contest/119/problem/CA classic dp problem, even though I knew this I still spent much time on figuring out the solution.As solving most dp problem, the difficult point is to find out the state transition equation.Before working on the state transition e...

Codeforces 845G Shortest Path Problem 原题codeforces845G 题意 给一个无向带权图,求1-n的异或最短路。 解题思路 因为我们是在异或的情况下求最短路,因此环是一个特殊的存在。 我们从一个点走向环,在环内绕一圈再回到当前点,我们只会获得环的权值。也就是说,对于一个环的权值,我们可以只考虑选与不选...
