DOI: 10.1103/physreve.99.050303
Abstract: Social networks are the prime channel for the spreading of computer viruses. Yet the study of their propagation neglects the temporal nature of social interactions and the heterogeneity of users' susceptibility. Here, we introduce a… read more here.

DOI: 10.1109/lcsys.2020.2971835
Abstract: Many existing distributed optimization algorithms are applicable to time-varying networks, whereas their convergence results are established under the standard $B$ -connectivity condition. In this letter, we establish the convergence of the Fenchel dual gradient methods,… read more here.

DOI: 10.1109/tac.2019.2901829
Abstract: We develop a family of Fenchel dual gradient methods for solving constrained, strongly convex, but not necessarily smooth multi-agent optimization problems over time-varying networks. The proposed algorithms are constructed on the basis of weighted Fenchel… read more here.
