Stability of a second order consensus algorithm with time delay
—In this paper, we investigate a second order consensus problem in a directed graph with non-uniform time delay. This problem arises naturally in real multi-agent systems such as...

Nearly Tight Low Stretch Spanning Trees
We prove that any graph G with n points has a distribution T over spanning trees such that for any edge (u, v) the expected stretch ET ∼T [dT (u, v)/dG(u, v)] is bounded by ˜O(...

Analysis of Dynamic Sensor Networks: Power Law Then What?
— Recent studies on wireless sensor networks (WSN) have shown that the duration of contacts and inter-contacts are power law distributed. While this is a strong property of these...

Pagerank Increase under Different Collusion Topologies
We study the impact of collusion –nepotistic linking– in a Web graph in terms of Pagerank. We prove a bound on the Pagerank increase that depends both on the reset probability...

Model generation for PRS-like agents
We develop a sound foundation for model checking algorithms for the class of PRS-style BDI agents, by showing how a reachability graph for any given PRS-type agent can be construc...
