Why there is no need to use a big-M in linear bilevel optimization: a computational study of two ready-to-use approaches

Kleinert, Thomas; Schmidt, Martin - In: Computational Management Science 20 (2023)

Linear bilevel optimization problems have gained increasing attention both in theory as well as in practical applications of Operations Research (OR) during the last years and decades. The latter is mainly due to the ability of this class of problems to model hierarchical decision processes....
