Computing generating sets of lattice ideals
Raymond Hemmecke, Peter Malkin
In this article, we present a new algorithm for computing a generating set of a lattice ideal. This algorithm is based on a project-and-lift approach and is implemented in 4ti2. We…

FPTAS for mixed-integer polynomial optimization with a fixed number of variables
Jesús A. De Loera, Raymond Hemmecke, Matthias Köppe +1
We show the existence of an FPTAS for the problem of maximizing a non-negative polynomial over mixed-integer sets in convex polytopes, when the number of variables is fixed.

Finiteness theorems in stochastic integer programming
Matthias Aschenbrenner, Raymond Hemmecke
We study Graver test sets for families of linear multi-stage stochastic integer programs with varying number of scenarios. We show that these test sets can be decomposed into finit…
