Abstract. In the constraint satisfaction problem (CSP), the aim is to find an assignment of values to a set of variables subject to specified constraints. In the minimum cost hom...
An algorithm and implementation is presented to compute the exact arrangement induced by arbitrary algebraic surfaces on a parametrized ring Dupin cyclide. The family of Dupin cyc...
Problem Solving Environments have a well established position as an essential tool for computational science. We focus our attention in this article on how to provide parallel com...
Ontologies are used as a means of expressing agreements to a vocabulary shared by a community in a coherent and consistent manner. As it happens in the Internet, ontologies are cr...
