WebMar 20, 2024 · This work concentrates on the problem of optimizing the cost of a passive wavelength division multiplexing (WDM) optical network used as a transport network for carrying the xHaul packet traffic between a set of remote radio sites and a central hub in a 5G radio access network (RAN). In this scope, we investigate the flexible use of optical … WebDec 30, 1998 · A dynamic optimization strategy is developed that makes use of existing differential−algebraic equation solvers and nonlinear programming strategies. In contrast to current dynamic optimization approaches, this approach applies an adjoint strategy for the calculation of objective function and constraint gradients. Furthermore, we consider two …
