    • Bilevel optimization based on iterative approximation of multiple mappings 

      Sinha, Ankur; Lu, Zhichao; Deb, Kalyanmoy; Malo, Pekka (Journal of Heuristics, 2020)
      A large number of application problems involve two levels of optimization, where one optimization task is nested inside the other. These problems are known as bilevel optimization problems and have been studied by both ...

    • Uncertainty handling in bilevel optimization for robust and reliable solutions 

      Lu, Zhichao; Deb, Kalyanmoy; Sinha, Ankur (World Scientific, 2018)
      Uncertainties in variables and parameters cause optimization problems to move away from globally-optimal and uncertain solutions. Practitioners resort to finding robust and reliable solutions in such situations. Bilevel ...
