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...

Heuristic Algorithms for Minimum Bandwith Consumption Multicast Routing in Wireless Mesh Networks
We study the problem of computing multicast trees with minimal bandwidth consumption in multi-hop wireless mesh networks. For wired networks, this problem is known as the Steiner t...

Filtering Algorithms for the NValue Constraint
Abstract. The NValue constraint counts the number of different values assigned to a vector of variables. Propagating generalized arc consistency on this constraint is NP-hard. We ...

A PDE viewpoint on basic properties of coordination algorithms with symmetries
Several recent control applications consider the coordination of subsystems through local interaction. Often the interaction has a symmetry in state space, e.g. invariance with res...

New efficient algorithms for computing effective capacitance
We describe a novel iterationless approach for computing the effective capacitance of an interconnect load at a driving gate output. Our new approach is considerably faster than p...
