KKT conditions for optimization with generalized invex fuzzy functions
Ville Rinne, Yury Nikulin, Marko M. Mäkelä
This paper explores optimality conditions in optimization problems involving generalized invex fuzzy functions. We extend the classical KKT framework to settings in which the objec…

On invex functions with same η in single and multivalued nonsmooth optimization with Clarke's subdifferential
Ville Rinne, Yury Nikulin, Marko Mäkelä
In this paper, a finite family of nonsmooth locally Lipschitz continuous functions that are invex with respect to the same function η are characterized in terms of their scalarize…
