Merkert, Maximilian; Orlinskaya, Galina; Weninger, Dieter - In: Journal of Global Optimization 84 (2022) 3, pp. 607-650
We propose an exact global solution method for bilevel mixed-integer optimization problems with lower-level integer variables and including nonlinear terms such as, e.g., products of upper-level and lower-level variables. Problems of this type are extremely challenging as a single-level...
