Polytope-based computation of polynomial ranges
Polynomial ranges are commonly used for numerically solving polynomial systems with interval Newton solvers. Often ranges are computed using the convex hull property of the tensor...

New Outer Bounds on the Marginal Polytope
We give a new class of outer bounds on the marginal polytope, and propose a cutting-plane algorithm for efficiently optimizing over these constraints. When combined with a concav...

Computing hereditary convex structures
Color red and blue the n vertices of a convex polytope P in R3 . Can we compute the convex hull of each color class in o(n log n)? What if we have χ > 2 colors? What if the co...

Low-Dimensional Faces of Random 0/1-Polytopes
Let P be a random 0/1-polytope in d with n(d) vertices, and denote by k(P) the k-face density of P, i.e., the quotient of the number of k-dimensional faces of P and `n(d) k+1

Random half-integral polytopes
We show that half-integral polytopes obtained as the convex hull of a random set of half-integral points of the 0/1 cube have rank as high as Ω(log n/ log log n) with positive pr...
