Catalogue 1 Problem Description 2 Solutions 2.1 Brute Force method 1 problem description Given a set of n points on a plane , its convex hull is the smallest convex polygon containing all of these points, and all points satisfying this condition are obtained. In addition, vivid description of the image:(1) We can think of this problem as how to use the shortest fence to surround an n-headed

Question: Some vertices are on an infinite graph, and each vertex can control some regions. This region satisfies that the arrival time of this vertex is strictly less than that of other vertices. Find the areas where infinite area can be controlled. Question: The control range for low speed is limited. The infinite area can be controlled only when the maximum speed is reached on the convex hull. The vertical line of any two points is the border, and

The topic is given n cops and m robbers and Q residents, if a resident in a three cops surrounded by a triangle is safe, otherwise, if in a certain three robbers surrounded by the triangle, is not safe, otherwise is neither.Idea: This can be converted into a convex hull to do. Determine if a resident is inside a convex hull.: Here is one of the convex hull's meth

Rt,graham scanning method to find convex hull is divided into 3 steps:1. Find the smallest point in Y2. With the smallest point o of Y as the origin, all remaining points are relative to the angle of O and are ordered from small to large at the polar angle.3.

Given two Convex Polygon that are not connected (that is, not intersecting)PAndQTo find the point at the minimum distance between them (P,Q)(PBelongPAndQBelongQ). In fact, polygon do not intersect, because the polygon we call contains all vertices inside it. If the polygon intersect, the minimum distance becomes meaningless. However, this is the problem. On the other hand, the minimum distance between the convex
