Abstract
Every convex polytope has both a vertex and a halfspace description. T he complexity of translating from the vertices to the halfspaces (conv ex hull) or vice versa (vertex enumeration) remains an important open problem in computational geometry. In this note we present families of hard polytopes for algorithms using pivoting, constraint insertion, a nd triangulation, and discuss techniques for estimating the difficulty of a convex hull or vertex enumeration instance.
