... combination of margin- adaptive and rate -adaptive optimization problems. It is important to mention here that margin adaptive objec tive does not include power constraint as it tries to minimize total ... convex due to the presence of bounding constraints. We propose a heuristic solution where in order to get a good starting point we solve the problem by ignoring the bounding...
