On the Linear Convergence of Distributed Optimization over Directed Graphs
Chenguang Xi, Usman A. Khan
This paper develops a fast distributed algorithm, termed \emph{DEXTRA}, to solve the optimization problem when~ agents reach agreement and collaboratively minimize the sum of th…

On the Distributed Optimization over Directed Networks
Chenguang Xi, Qiong Wu, Usman A. Khan
In this paper, we propose a distributed algorithm, called Directed-Distributed Gradient Descent (D-DGD), to solve multi-agent optimization problems over directed graphs. Existing a…

Localization in mobile networks via virtual convex hulls
Sam Safavi, Usman A. Khan
In this paper, we develop a \textit{distributed} algorithm to localize an arbitrary number of agents moving in a bounded region of interest. We assume that the network contains \te…
