Continuous Delivery Message Dissemination Problems under the Multicasting Communication Mode
We consider the Continuous Delivery Message Dissemination (CDMD) problem over the n-processor single-port complete (all links are present and are bidirectional) static network with...

Subgradient methods and consensus algorithms for solving convex optimization problems
— In this paper we propose a subgradient method for solving coupled optimization problems in a distributed way given restrictions on the communication topology. The iterative pro...

SDP-Based Algorithms for Maximum Independent Set Problems on Hypergraphs
Abstract. This paper deals with approximations of maximum independent sets in non-uniform hypergraphs of low degree. We obtain the first performance ratio that is sublinear in term...
