Abstract: In this paper we present a truly practical and provably optimal O(n log h) time outputsensitive algorithm for the planar convex hull problem. The basic algorithm is similar to the algorithm presented in Chan, Snoeyink and Yap[2] where the median-finding step is replaced by an approximate median. We analyze two such schemes and show that for both methods, the algorithm runs in expected O(n log h) time. The expected number of comparisons can be made smaller than 5n log h for the upper-hull. We... (Update)
