The Gomory-Chvatal closure of a non-rational polytope is a rational polytope

Abstract: The question as to whether the Gomory-Chvatal closure of a non-rational polytope is a polytope has been a longstanding open problem in integer programming. In this paper, we answer this question in the affirmative, by combining ideas from polyhedral theory and the geometry of numbers.

Keywords: Gomory-Chvatal closure, polytopes, integer programming, lattices, reduced bases

Category 1: Integer Programming
