The Bipartite Boolean Quadric Polytope with Multiple-Choice Constraints
Andreas Bärmann, Alexander Martin, Oskar Schneider
We consider the bipartite boolean quadric polytope (BQP) with multiple-choice constraints and analyse its combinatorial properties. The well-studied BQP is defined as the convex hu…
An Online-Learning Approach to Inverse Optimization
Andreas Bärmann, Alexander Martin, Sebastian Pokutta +1
In this paper, we demonstrate how to learn the objective function of a decision-maker while only observing the problem input data and the decision-maker's corresponding decisions o…
Pricing and clearing combinatorial markets with singleton and swap orders: Efficient algorithms for the futures opening auction problem
Johannes C. Müller, Sebastian Pokutta, Alexander Martin +3
In this article we consider combinatorial markets with valuations only for singletons and pairs of buy/sell-orders for swapping two items in equal quantity. We provide an algorithm…
Strict linear prices in non-convex European day-ahead electricity markets
Alexander Martin, Johannes C. Müller, Sebastian Pokutta
The European power grid can be divided into several market areas where the price of electricity is determined in a day-ahead auction. Market participants can provide continuous hou…
