Optimality Conditions for Nondifferentiable Minimax Programs and Vector Optimization Problems.

First-order sufficient optimality conditions in terms of Lagrangian functions and Lagrange multipliers for nondifferentiable minimax programs and vector optimization problems in an Asplund space setting are obtained in this paper. Two illustrative examples are given. Our results implement the first-order necessary optimality conditions of Chuong and Kim (Ann Oper Res 251:73–87, 2017). [ABSTRACT FROM AUTHOR]
