Curing Epidemics on Networks using a Polya Contagion Model
Mikhail Hayhoe, Fady Alajaji, Bahman Gharesifard
We study the curing of epidemics of a network contagion, which is modelled using a variation of the classical Polya urn process that takes into account spatial infection among neig…
A Lie bracket approximation approach to distributed optimization over directed graphs
Simon Michalowsky, Bahman Gharesifard, Christian Ebenbauer
We consider a group of computation units trying to cooperatively solve a distributed optimization problem with shared linear equality and inequality constraints. Assuming that the…
Distinguished Sets of Semi-simple Lie Algebras
Xudong Chen, Bahman Gharesifard
We call a finite, spanning set of a semi-simple real Lie algebra a distinguished set if it satisfies the following property: The Lie bracket of any two elements out of the set is,…
Controllability of coupled parabolic systems with multiple underactuations: parts I and II
Drew Steeves, Bahman Gharesifard, Abdol-Reza Mansouri
This work studies the null controllability of a system of coupled parabolic PDEs. In particular, our work specializes to an important subclass of these control problems which are c…
Push-sum on random graphs
Pouya Rezaeinia, Bahman Gharesifard, Tamas Linder +1
In this paper, we study the problem of achieving average consensus over a random time-varying sequence of directed graphs by extending the class of so-called push-sum algorithms to…
Distributed Submodular Maximization with Limited Information
Bahman Gharesifard, Stephen L. Smith
We consider a class of distributed submodular maximization problems in which each agent must choose a single strategy from its strategy set. The global objective is to maximize a s…
A Polya Contagion Model for Networks
Mikhail Hayhoe, Fady Alajaji, Bahman Gharesifard
A network epidemics model based on the classical Polya urn scheme is investigated. Temporal contagion processes are generated on the network nodes using a modified Polya sampling s…
