I only and there are O(n) of these. It is also interesting to note that for a random arrangement of lines, under almost any definition of random line, the expected number of vertices on the convex hull of I is O(1) [DT90]. An arrangement of six lines and their convex hull is il...

A fast algorithm for convex hull of the planar points is presented.The algorithm firstly makes the discrete points sorted in scan manner,construct the initial convex hull,then add the rest of the discrete points to the convex hull which has been created and generate a new convex hull.Experiment...
5可以证明,上述两种定义是等价的67概念81. 点集Q的凸包(convex hull)是指一个最小凸多边形,满足Q中的点9或者在多边形边上或者在其内。102. 一组平面上的点,求一个包含所有点的最小的凸多边形,这就是凸包11问题了。这可以形象地想成这样:在地上放置一些不可移动的木桩,用12一根绳子把他们尽量紧地圈起来,...
