On the Number of Pseudo-empty Convex Pentagons for a Planar Point Set
摘要/Abstract
摘要:
设P表示处于一般位置的平面点集,P的子集T所确定的凸多边形CH(T)称为次空凸多边形,若CH(T)的内部至多含有P中的1个点.研究了P能确定的不交的次空凸五边形的最大个数问题.
Abstract:
Let P be a set of points in general position in a plane.For P T,the convex polygon CH(T) determined by T is called a pseudo-empty.If there is at most one point of P lying in the interior of CH(T).The maximum number of disjoint pseudo-empty convex pentagons determined by P is estimated.
