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…

Admissibility of solution estimators for stochastic optimization

Amitabh Basu, Tu Nguyen, Ao Sun

We look at stochastic optimization problems through the lens of statistical decision theory. In particular, we address admissibility, in the statistical decision theory sense, of t…

Mixed-integer bilevel representability

Amitabh Basu, Christopher Thomas Ryan, Sriram Sankaranarayanan

We study the representability of sets that admit extended formulations using mixed-integer bilevel programs. We show that feasible regions modeled by continuous bilevel constraints…

Can cut generating functions be good and efficient?

Amitabh Basu, Sriram Sankaranarayanan

Making cut generating functions (CGFs) computationally viable is a central question in modern integer programming research. One would like to find CGFs that are simultaneously good…
