WebAs the constructed optimization problem is non-convex, we introduced auxiliary and relaxation variables to relax the original problem and used the SCA algorithm to solve the new relaxation problem. To obtain a well-localized optimal solution with the SCA algorithm, we propose a fast initialization path method that is based on a CFC for processing. stick texting https://brain4more.com
