You are to write a program to find a circle which covers a set of points and has the minimal area. There will be no more than 100 points in one problem. Input The input contains several problems. The first line of each problem is a line containing on…

ZOJ1450 给定N个点(N<=100)求最小的圆把这些点全部覆盖 考虑对于三角形,可以唯一的找到外接圆,而多边形又可以分解为三角形,所以对于多边形也可以找到唯一的最小覆盖圆. #include<iostream> #include<stdio.h> #include<stdlib.h> #include<string.h> #include<math.h> #include<algorithm> #include<qu…

//第一期 计算几何题的特点与做题要领: 1.大部分不会很难,少部分题目思路很巧妙 2.做计算几何题目,模板很重要,模板必须高度可靠. 3.要注意代码的组织,因为计算几何的题目很容易上两百行代码,里面大部分是模板.如果代码一片混乱,那么会严重影响做题正确率. 4.注意精度控制. 5.能用整数的地方尽量用整数,要想到扩大数据的方法(扩大一倍,或扩大sqrt2).因为整数不用考虑浮点误差,而且运算比浮点快. 一.点,线,面,形基本关系,点积叉积的理解 POJ 2318 TOYS(推荐) http:/…
