Angelic nondeterminism can play an important role in program development. It simplifies specifications, for example in deriving programs with a refinement calculus; it is the form...
Abstract. We introduce the notion of array-based system as a suittraction of infinite state systems such as broadcast protocols or sorting programs. By using a class of quantified-...
Abstract. Software applications are inevitably concerned with data integrity, whether the data is stored in a database, files, or program memory. An integrity guard is code execut...
Abstract. In this paper we apply answer set programming to solve alternating Boolean equation systems. We develop a novel characterization of solutions for variables in disjunctive...
Dierence Bound Matrices (DBMs) are the most commonly used data structure for model checking timed automata. Since long they are being used in successful tools like Kronos or UPPAA...
