摘要
在研究中轴性质的基础上,给出了一种全新的求解凸多边形直径算法。该算法首先求出凸多边形的中轴,再根据中轴的两个端点确定直径。算法简单,并在无预处理的情况下达到了O(n)。
A brand new algorithm for computing the diameter of a convex polygon is proposed,based on the research on the properties of the middle medial axis for a convex polygon.First the middle axis of a convex polygon is determined,then the diameter of the polygon can be computed by the two end points of the middle axis.The algorithm has no pre-processing,and its time complexity is O(n).
