Role of (ρ, η, A)-invexity to ϵ-optimality conditions for multiple objective fractional programming

Abstract

Based on a general framework for a class of (ρ,η,A)-invex n-set functions, some results on the ϵ-optimality conditions for multiple objective fractional programming problems are established. The obtained results are not only general in nature, but also unify results on generalized invexity to the context of multiple fractional programming.
