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…
An extreme function which is nonnegative and discontinuous everywhere
Amitabh Basu, Michele Conforti, Marco Di Summa
We consider Gomory and Johnson's infinite group model with a single row. Valid inequalities for this model are expressed by valid functions and it has been recently shown that any…
