A Unifying Primal-Dual Proximal Framework for Distributed Nonconvex Optimization

Zichong Ou, Jie Lu

We consider distributed nonconvex optimization over an undirected network, where each node privately possesses its local objective and communicates exclusively with its neighboring…

Robust Distributed Nonconvex Optimization Enabling Communication Acceleration and Privacy Protection

Zichong Ou, Jie Lu

This paper addresses a distributed nonconvex optimization problem over multi-agent networks, where each agent exchanges its local information solely with its neighbors. Given that…

A Unified Dual Consensus Approach to Distributed Optimization with Globally-Coupled Constraints

Zixuan Liu, Xuyang Wu, Dandan Wang +1

This article explores distributed convex optimization with globally-coupled constraints, where the objective function is a general nonsmooth convex function, the constraints includ…
