Large Scale Resource Allocation for the Internet of Things Network Based on ADMM

IEEE Access, 2020
Large scale deployment of Internet of Things (IoT) devices poses challenges in resource allocation. In this paper, alternating direction method of multipliers (ADMM) is adopted to solve such large scale resource allocation problems.

Research on Multibeam Pattern Synthesis of Time Modulated Array Based on Convex Optimization

International Journal of Antennas and Propagation, 2021
An efficient multibeam pattern synthesis method for time modulated array (TMA) is proposed in this paper. The aim of this method is to generate a beam pattern on the specified sideband of TMA. The pattern synthesis problem is divided into two stages.

Are Convex Optimization Curves Convex?

In this paper, we study when we might expect the optimization curve induced by gradient descent to be \emph{convex} -- precluding, for example, an initial plateau followed by a sharp decrease, making it difficult to decide when optimization should stop.

A new accelerated algorithm with a linesearch technique for convex bilevel optimization problems with applications

AIMS Mathematics
We considered a convex bilevel optimization problem when the outer level problem was to find a minimizer of a strongly convex function over the set of solutions of the inner level problem which was in the form of minimization of the sum of a convex ...
