We prove a parameterized analog of Schaefer’s Dichotomy Theorem: we show that for every finite boolean constraint family F, deciding whether a formula containing constraints fr...
We present a simple and effective approximated backward reachability algorithm for parameterized systems with existentially and universally quantified global conditions. The indivi...

In a constraint satisfaction problem (CSP) the goal is to find an assignment of a given set of variables subject to specified constraints. A global cardinality constraint is an ...
Abstract. We propose a verification method for parameterized systems with global conditions. The method is based on context-sensitive constraints, a symbolic representation of infi...
