Finally, after trying some #math stuff, I found my real destination: talking about #Trappist beers 🍻🤪 … if you have some spear time over the weekend, here you get some Trappist nerd information … youtu.be/tqCWoacNajk?si…

A lot is changing, but some things never do! In 1st grade (👇), #math was already one of my favorites. Now, I'm leaving @TrierUni after 9 great years of studying it. If all had gone to plan, I'd have left 4 years ago and missed out on discovering my passion for #orms… a 🧵 1/8

Thanks to all participants of the @ALOP_Trier autumn school on "Constrained #Optimization & #MachineLearning" for attending and for making it such a great workshop! In particular, thanks to Tim Hoheisel, @emiliocarrizosa and @69alodi for giving three wonderful series of lectures

Update to our #orms paper on heuristics for Γ-Robust #bilevel problems (jointly with @ILjubic and @schmaidt)! We've extended our computational study on 2240 instances and now compare to both exact and heuristic methods from the literature. Full details: optimization-online.org/?p=26186

Finally, some paper news: Our preprint "On Coupling Constraints in Linear #Bilevel #Optimization" has been accepted in Optimization Letters & will be soon available via #OpenAccess. Here's the latest preprint version as well: optimization-online.org/?p=25680 @thuerauf_j @hri_lefebvre

In my new work I study k-adaptability problems which can be used to approximate two-stage robust optimization problems. I derive bounds on k which guarantee optimality. Link: arxiv.org/abs/2409.12630 #robustoptimization #kadaptability

Just learned that together with Albert S. Berahas, Majid Jahani and Martin Takáč we've won the Charles Broyden Prize for the paper "Quasi-Newton methods for deep learning: forget the past, just sample". Super unexpected and nice!!!
