Complexity of branch-and-bound and cutting planes in mixed-integer optimization -- II

Amitabh Basu, Michele Conforti, Marco Di Summa +1

We study the complexity of cutting planes and branching schemes from a theoretical point of view. We give some rigorous underpinnings to the empirically observed phenomenon that co…

Complexity of branch-and-bound and cutting planes in mixed-integer optimization

Amitabh Basu, Michele Conforti, Marco Di Summa +1

We investigate the theoretical complexity of branch-and-bound (BB) and cutting plane (CP) algorithms for mixed-integer optimization. In particular, we study the relative efficiency…

Split cuts in the plane

Amitabh Basu, Michele Conforti, Marco Di Summa +1

We provide a polynomial time cutting plane algorithm based on split cuts to solve integer programs in the plane. We also prove that the split closure of a polyhedron in the plane h…

A geometric approach to cut-generating functions

Amitabh Basu, Michele Conforti, Marco Di Summa

The cutting-plane approach to integer programming was initiated more that 40 years ago: Gomory introduced the corner polyhedron as a relaxation of a mixed integer set in tableau fo…

On the convergence of the affine hull of the Chvátal-Gomory closures

Gennadiy Averkov, Michele Conforti, Alberto Del Pia +2

Given an integral polyhedron P and a rational polyhedron Q living in the same n-dimensional space and containing the same integer points as P, we investigate how many iterations of…
