Estimating Sequences with Memory for Minimizing Convex Non-smooth Composite Functions
Endrit Dosti, Sergiy A. Vorobyov, Themistoklis Charalambous
First-order optimization methods are crucial for solving large-scale data processing problems, particularly those involving convex non-smooth composite objectives. For such problem…
Asynchronous Distributed Optimization via ADMM with Efficient Communication
Apostolos I. Rikos, Wei Jiang, Themistoklis Charalambous +1
In this paper, we focus on an asynchronous distributed optimization problem. In our problem, each node is endowed with a convex local cost function, and is able to communicate with…
A Privacy-Preserving Finite-Time Push-Sum based Gradient Method for Distributed Optimization over Digraphs
Xiaomeng Chen, Wei Jiang, Themistoklis Charalambous +1
This paper addresses the problem of distributed optimization, where a network of agents represented as a directed graph (digraph) aims to collaboratively minimize the sum of their…
Fully Distributed Alternating Direction Method of Multipliers in Digraphs via Finite-Time Termination Mechanisms
Wei Jiang, Themistoklis Charalambous
In this work, we consider the distributed optimization problem in which each node has its own convex cost function and can communicate directly only with its neighbors, as determin…
An Asynchronous Approximate Distributed Alternating Direction Method of Multipliers in Digraphs
Wei Jiang, Andreas Grammenos, Evangelia Kalyvianaki +1
In this work, we consider the asynchronous distributed optimization problem in which each node has its own convex cost function and can communicate directly only with its neighbors…
Optimal Scheduling of Downlink Communication for a Multi-Agent System with a Central Observation Post
Mario Zanon, Themistoklis Charalambous, Henk Wymeersch +1
In this paper, we consider a set of agents, which may receive an observation of their state by a central observa- tion post via a shared wireless network. The aim of this work is t…
