On nonsmooth minimax programming problems containingV-ρ-invexity
Hun Kuk, Tetsuzo Tanino · Journal of Information and Optimization Sciences · 2000
We consider a class of nonsmooth minimax programming problems in which functions are locally Lipschitz. Necessary and sufficient optimality conditions and duality theorems for nonsmooth minimax programming problems are obtained under Vρ-invexity assumptions on objective and constraint functions
