We propose in this paper a systematic study which is a variational approach of approximate optimality conditions in terms of Ekeland’s variational principle and some of its applications. Using a generalised differentiation sub-differentiability theory for non-smooth functions, new properties are then identified and approximate optimality conditions are established in the cases: convex, locally Lipschitz and finally lower semi-continuous.
