On solving integer bilevel optimization problems with a non-convex quadratic follower objective function using disjunctive cuts
Kübra Tanınmış, Elisabeth Gaar, Jon Lee +2
In this work, we study bilevel optimization problems where all variables are integer, all constraints and the leader objective function are linear, and the follower objective funct…
An semidefinite programming-based -constraint method for the bi-objective single-row facility layout problem
Christof Brandstetter, Elisabeth Gaar, Markus Sinnl
In this work, we introduce a multi-objective version of the well-known single-row facility layout problem (SRFLP). In the SRFLP, a set of one-dimensional facilities should be place…
A note on the maximal covering location problem with customer preference ordering
Elisabeth Gaar, Markus Sinnl
Recently a series of papers introduced and investigated the maximal covering location problem with customer preference ordering, a variant of the classical maximal covering locatio…
Investigating mixed-integer programming approaches for the --closest-center problem
Elisabeth Gaar, Sara Joosten, Markus Sinnl
In this work, we introduce and study the --closest-center problem (CCP), which generalizes the -second-center problem, a recently emerged variant of the classical -…
