The repository contains the computationally ill-behaved bilevel problem presented in the paper
On a Computationally Ill-Behaved Bilevel Problem with a Continuous and Nonconvex Lower Level
by Yasmine Beck, Daniel Bienstock, Martin Schmidt, and Johannes Thürauf (2023) (https://link.springer.com/article/10.1007/s10957-023-02238-9).
The example is implemented in Python and uses Gurobi to solve all arising optimization problems.
