让你在平面上取一个点,使得其到给定的所有点的距离和最小. 就是“费马点”. 模拟退火……日后学习一下,这是从网上扒的,先存下. #include<iostream> #include<cstdio> #include<cstdlib> #include<cmath> #include<ctime> using namespace std; int n; double xx,yy,ans,t; struct point{double x,y;}p[…

题意: 给定S1串,长度100w,S2串,长度1k.问它俩的LCS. f(i,j)表示S2串前i个字符,LCS为j时,最少需要的S1串的前缀长度.转移的时候,枚举下一个字符在S1的位置即可.(可以预处理出S1中每个字符出现位置的vector,在其中二分)…

一个区域,垂直分成三块,每块有一个速度限制,问你从左下角跑到右上角的最短时间. 将区域看作三块折射率不同的介质,可以证明,按照光路跑时间最短. 于是可以二分第一个入射角,此时可以推出射到最右侧边界上的位置,看什么时候恰好射到右上角即可. 这份sb代码貌似挂精度了. #include<cstdio> #include<iostream> #include<cmath> using namespace std; #define EPS 0.0000000001 int T,…
