Fast randomized parallel methods for planar convex hull construction

We present a number of efficient parallel algorithms for constructing 2-dimensional convex hulls on a randomized CRCW PRAM. Specifically, we show how to build the convex hull of n presorted points in the plane in O(1) time using O( n log n) work, with n-exponential probability, or, alternately, in O...
