New lower bounds for halfspace emptiness

Research output: Contribution to journalConference articlepeer-review

Abstract

We derive a lower bound of Ω(n4/3) for the half-space emptiness problem: Given a set of n points and n hyperplanes in IR5, is every point above every hyperplane? This matches the best known upper bound to within polylogarithmic factors, and improves the previous best lower bound of Ω(n log n). The lower bound applies to partitioning algorithms in which every query region is a polyhedron with a constant number of facets.
