Luce Brotcorne, Christoph Buchheim, Dick den Hertog, and Dorothee Henke. Optimization at the Second Level (Dagstuhl Seminar 22441). In Dagstuhl Reports, Volume 12, Issue 10, pp. 207-224, Schloss Dagstuhl – Leibniz-Zentrum für Informatik (2023)


This report documents the program and the outcomes of Dagstuhl Seminar 22441 "Optimization at the Second Level". The seminar was held on October 30 - November 4, 2022 in Schloss Dagstuhl - Leibniz-Zentrum für Informatik. Participants gave overview talks and presented recent results in bilevel, robust, and stochastic optimization. These three areas have in common that they typically deal with optimization problems which are contained in the second level of the polynomial hierarchy. The goal of the seminar was to bring together experts of bilevel, robust, and stochastic optimization in order to connect and work towards new insights and approaches for such problems. During the seminar, the relationships between these different areas of optimization were intensively discussed and interesting connections were identified.
