On the basis of a case-study, we demonstrate the usefulness of topology invariants for model-driven systems development. Considering a graph grammar semantics for a relevant fragme...
Abstract. This paper proposes a diagnosis algorithm for locating a certain kind of errors in logic programs: variable binding errors that result act symptoms during compile-time ch...
Abstract. The vertex cover problem is a classical NP-complete problem for which the best worst-case approximation ratio is 2− o(1). In this paper, we use a collection of simple g...
The ForSyDe methodology has been developed for system level design. Starting with a formal specification model, that captures the functionality of the system at a high abstractio...
Abstract. Class extensions provide a fine-grained mechanism to define incremental modifications to class-based systems when standard subclassing mechanisms are inappropriate. To...
