Competitive analysis of organization networks or multicast acknowledgement: how much to wait?
We study, from the competitive analysis perspective, the trade off between communication cost and delay cost (or simply the sendor-wait dilemma) on a hierarchy (rooted tree). The p...

Wideband spectral estimation from compressed measurements exploiting spectral a priori information in Cognitive Radio systems
In Cognitive Radio scenarios channelization information from primary network may be available to the spectral monitor. Under this assumption we propose a spectral estimation algor...

Lagrangean duals and exact solution to the capacitated p-center problem
In this work we study the Capacitated p-Center Problem (CpCP) and we propose an exact algorithm to solve it. We study two auxiliary problems and their relation to CpCP, and we pro...

A mean-variance model for the minimum cost flow problem with stochastic arc costs
This paper considers a minimum cost flow problem where arc costs are uncertain, and the decision maker wishes to minimize both the expected flow cost and the variance of this co...
