ON SUFFICIENCY IN MULTIOBJECTIVE PROGRAMMING INVOLVING GENERALIZED (G, C, ρ)-TYPE I FUNCTIONS.

In this paper, a new class of (G, C, ρ)-type I functions and their generalizations are introduced. We consider a class of differentiable multiobjective optimization problems and establish sufficient optimality conditions. The results of the paper are more general than those existing in the literature. [ABSTRACT FROM AUTHOR]
