Convexificators for nonconvex multiobjective optimization problems with uncertain data: robust optimality and duality
Chen, Jiawei; Yang, Ruixi; Köbis, Elisabeth Anna Sophia; Ou, Xiaoqing (Peer reviewed; Journal article, 2023)In this paper, we investigate robust optimality conditions and duality for a class of nonconvex multiobjective optimization problems with uncertain data in the worst case by the upper semi-regular convexificator. The Fermat ... -
Robust duality and saddle point characterizations for nonconvex multiobjective optimization with data uncertainty
Chen, Jiawei; Yang, Ruixi; Köbis, Elisabeth Anna Sophia; Zhang, Tao (Journal article, 2023)This paper is devoted to investigate the robust duality and saddle point characterizations of nonconvex multiobjective optimization with data uncertainty in both the objective and constraints. Based on the robust necessary ...
