On the Performance of Gradient Tracking with Local Updates

Edward Duc Hien Nguyen, Sulaiman A. Alghunaim, Kun Yuan +1

We study the decentralized optimization problem where a network of agents seeks to minimize the average of a set of heterogeneous non-convex cost functions distributedly. State…

Can Primal Methods Outperform Primal-dual Methods in Decentralized Dynamic Optimization?

Kun Yuan, Wei Xu, Qing Ling

In this paper, we consider the decentralized dynamic optimization problem defined over a multi-agent network. Each agent possesses a time-varying local objective function, and all…
