Rectilinear Convex Hull with minimum area

Computational Geometry 2017-12-29 v2

Abstract

Let PP be a planar set of nn points in general position. We consider the problem of computing an orientation of the plane for which the Rectilinear Convex Hull of PP has minimum area. Bae et al. (Computational Geometry: Theory and Applications, Vol. 42, 2009) solved the problem in quadratic time and linear space. We describe an algorithm that reduces this time complexity to Θ(nlogn)\Theta(n \log n).
