On the Convergence of Inexact Gradient Descent with Controlled Synchronization Steps
Sandushan Ranaweera, Chathuranga Weeraddana, Prathapasinghe Dharmawansa +1
We develop a gradient-like algorithm to minimize a sum of peer objective functions based on coordination through a peer interconnection network. The coordination admits two stages:…

Hansi Abeynanda, Chathuranga Weeraddana, G. H. J. Lanel +1
With the unprecedented growth of signal processing and machine learning application domains, there has been a tremendous expansion of interest in distributed optimization methods t…
Voltage Control Using Limited Communication
Sindri Magnusson, Guannan Qu, Carlo Fischione +1
In electricity distribution networks, the increasing penetration of renewable energy generation necessitates faster and more sophisticated voltage controls. Unfortunately, recent r…
Convergence of Limited Communications Gradient Methods
Sindri Magnusson, Chinwendu Enyioha, Na Li +2
Distributed optimization increasingly plays a central role in economical and sustainable operation of cyber-physical systems. Nevertheless, the complete potential of the technology…
On the Convergence of Alternating Direction Lagrangian Methods for Nonconvex Structured Optimization Problems
Sindri Magnússon, Pradeep Chathuranga Weeraddana, Michael G. Rabbat +1
Nonconvex and structured optimization problems arise in many engineering applications that demand scalable and distributed solution methods. The study of the convergence properties…
Optimality of Radio Power Control via Fast-Lipschitz Optimization
Martin Jakobsson, Carlo Fischione
Fixed point algorithms play an important role to compute feasible solutions to the radio power control problems in wireless networks. Although these algorithms are shown to converg…
