Abstract:
The aim of the present paper is to provide a formula for the ε - subdifferential of f + g o h different from the ones which can be found in the existent literature. Further we equivalently characterize this formula by using of a so-called closedness type regularity condition expressed by means of the epigraphs of the conjugates of the functions involved. Even more, using the ε - subdifferential formula we are able to derive necessary and sufficient conditions for the ε - optimal solutions of composed convex optimization problems.
Keywords:
