Branching-time model-checking of probabilistic pushdown automata
In this paper we study complexity of the model-checking problem for probabilistic pushdown automata (pPDA) and qualitative fragments of two branching-time logics PCTL∗ and PECTL∗. We prove that this problem is in 2-EXPTIME for pPDA and qualitative PCTL∗. Consequently, we prove that model-checking of stateless pPDA (pBPA) and both qualitative PCTL∗ and qualitative PECTL∗ is 2-EXPTIME-hard. These...
متن کاملModel-Checking of Ordered Multi-Pushdown Automata
We address the verification problem of ordered multi-pushdown automata: A multi-stack extension of pushdown automata that comes with a constraint on stack transitions such that a pop can only be performed on the first non-empty stack. First, we show that the emptiness problem for ordered multi-pushdown automata is in 2ETIME. Then, we prove that, for an ordered multi-pushdown automata, the set o...
متن کاملOn probabilistic pushdown automata
We study the most important probabilistic computation modes for pushdown automata. First we show that deterministic pushdown automata (pda) are weaker than Las Vegas pda, which in turn are weaker than one-sided-error pda. Next one-sidederror pda are shown to be weaker than (nondeterministic) pda. Finally bounded error two-sided error pda and nondeterministic pda are incomparable. To show the li...

متن کاملModel Checking Probabilistic Timed Automata
Probabilistic timed automata are an extension of timed automata with discrete probability distributions. We consider model-checking algorithms for the subclasses of probabilistic timed automata which have one or two clocks. Firstly, we show that PCTL probabilistic model-checking problems (such as determining whether a set of target states can be reached with probability at least 0.99 regardless...
