Distributed receding horizon control for multi-vehicle formation stabilization
We consider the control of interacting subsystems whose dynamics and constraints are decoupled, but whose state vectors are coupled non-separably in a single cost function of a fi...

Cache-Friendly implementations of transitive closure
In this paper we show cache-friendly implementations of the Floyd-Warshall algorithm for the All-Pairs ShortestPath problem. We first compare the best commercial compiler optimiza...

Managing the operator ordering problem in parallel databases
This paper focuses on parallel query optimization. We consider the operator problem and introduce a new class of execution strategies called Linear-Oriented Bushy Trees (LBTs). Co...

Smoothing Nonlinear Conjugate Gradient Method for Image Restoration Using Nonsmooth Nonconvex Minimization
Image restoration problems are often converted into large-scale, nonsmooth and nonconvex optimization problems. Most existing minimization methods are not efficient for solving su...
