We propose the use of scatter search with path relinking for the inference of phylogenetic trees. Solutions are here represented as trees whose leaves span the set of species unde...
In this article we examine the architecture of an entity used for automatic management and provisioning of resources for DiffServ networks. We examine the existing literature and ...
We present a hybrid group key management protocol that incorporates both a centralized and a contributory scheme for key management, and a tree-based Elliptic Curve Diffie-Hellman...
Hierarchical matrices (H-matrices) approximate matrices in a data-sparse way, and the approximate arithmetic for H-matrices is almost optimal. In this paper we present an algebrai...
We discuss the design and high-performance implementation of collective communications operations on distributed-memory computer architectures. Using a combination of known techni...
