A NOTE ON THE EXTENSION COMPLEXITY OF THE KNAPSACK POLYTOPE Published: 2013/02/20 Sebastian PokuttaMathieu Van VyveCategories 0-1 Programming, Integer Programming, Polyhedra Tags approximation algorithms, extension complexity, knapsack polytope Short URL: https://optimization-online.org/?p=12332 We show that there are 0-1 and unbounded knapsack polytopes with super-polynomial extension complexity. More specifically, for each n in N we exhibit 0-1 and unbounded knapsack polyhedra in dimension n with extension complexity \Omega(2^\sqrt{n}). ArticleDownload View PDF
