Systems and protocols combining concurrency and infinite state space occur quite often in practice, but are very difficult to verify automatically. At the same time, if the system ...
In this work we introduce event-driven grammars, a kind of graph grammars that are especially suited for visual modelling environments generated by meta-modelling. Rules in these g...
Abstract— We present a novel algorithm to perform continuous collision detection(CCD) between non-rigid, deformable models using local advancement. Given the initial and final c...
Abstract. We present the tool MERIT, a CEGAR model-checker for safety propf counter-systems, which sits in the Lazy Abstraction with Interpolants (LAWI) framework. LAWI is parametr...
Higher-order pushdown systems (PDSs) generalise pushdown systems through the use of higher-order stacks, that is, a nested “stack of stacks” structure. These systems may be us...
