Dear reviewers, we greatly appreciate your remarks and suggestions. We will address the comments in the following. I don't think this is the case, since the primal-dual Could the authors clarify this? We will correct this accordingly. If we have an ɛ-optimal solution of Eq(2) (i.e., Definition 4.1), we can read from it a solution (x, y, z) whose Shouldn't the supremum be over w, instead of x? Page 7, line 253.
