Approximated set-valued mapping approach for handling multiobjective bilevel problems
(Elsevier Ltd, 2017)
A significant amount of research has been done on bilevel optimization problems both in the realm of classical and evolutionary optimization. However, the multiobjective extensions of bilevel programming have received ...
Evolutionary algorithm for bilevel optimization using approximations of the lower level optimal solution mapping
(Elsevier B.V., 2017)
Bilevel optimization problems are a class of challenging optimization problems, which contain two levels of optimization tasks. In these problems, the optimal solutions to the lower level problem become possible feasible ...
