Mohammad Khaledian, Esmaile Khorram, Behrooz Karimi · Optimization methods & software · 2014
In this paper, new necessary and sufficient conditions for characterizing ϵ-properly efficient solutions and new necessary conditions for characterizing ϵ-(weakly) efficient solutions of multiple objective optimization problems are presented. Note that all of the provided results are established without any convexity and boundedness assumptions on the problem under consideration.
