Approximation Algorithm for QoS Routing with Multiple Additive Constraints
—In this paper, we study the problem of computing the supported QoS from a source to a destination with multiple additive constraints. The problem has been shown to be NP-complet...

Geometric weakly admissible meshes, discrete least squares approximations and approximate Fekete points
Using the concept of Geometric Weakly Admissible Meshes (see §2 below) together with an algorithm based on the classical QR factorization of matrices, we compute efficient points...
