The game-theory weeks go on 😀

Today: How to solve a GNEP by solving a NEP? Here is the answer in our new paper "A One-Extra Player Reduction of GNEPs to NEPs" (jointly with David Salas from Chile and @hlefebvr.bsky.social from @unitrier.bsky.social):

The burial of coupling constraints in bilevel optimization!

You don't need them. Here are all the details: "On Coupling Constraints in Pessimistic Linear Bilevel Optimization" (joint work with Dorothee Henke, @hlefebvr.bsky.social, and Johannes Thürauf).

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.
