Abstract

We present a deterministic algorithm for computing the convex hull of n points in E d in optimal O(n log n+n {down left corner}d/2{down right corner} ) time. Optimal solutions were previously known only in even dimension and in dimension 3. A by-product of our result is an algorithm for computing the Voronoi diagram of n points in d-space in optimal O(n log n+n {top left corner}d/2{top right corner} ) time.
