Global Model Checking of Ordered Multi-Pushdown Systems

Mohamed Faouzi Atig
In this paper, we address the verification problem of ordered multi-pushdown systems: A multi-stack extension of pushdown systems that comes with a constraint on stack operations such that a pop can only be performed on the first non-empty stack. First, we show that for an ordered multi-pushdown system the set of all predecessors of a regular set of configurations is an effectively constructible regular set. Then, we exploit this result to solve the global model...
