I visited Stockholm to participate in STOGO25.. and the city has some cool vibe (a little bit melancholic mood... because of the weather?)

Can #bilevel #optimization help to solve challenging #robust optimization problems?
Maybe … here’s our first numerical study on this topic:
"Solving Decision-Dependent Robust Problems as Bilevel Optimization Problems"
Jointly with H. Lefebvre, S. Stevens, and J. Thürauf.
