The presented framework focuses on probabilistic reachability, which is a core problem in verification, and is instantiated in two distinct scenarios.

In this paper, we provide the first stopping criteria for VI on SG with total reward and mean payoff, yielding the first anytime algorithms in these settings.

In contrast, support vector machines provide a more powerful representation, capable of discovering many such relationships, but not in an explainable form.

We provide the first algorithm to compute mean payoff probably approximately correctly in unknown MDP; further, we extend it to unknown CTMDP.

As this problem is undecidable in general, assumptions on the MDP are necessary.

While abstraction is a classic tool of verification to scale it up, it is not used very often for verifying neural networks.

In particular the latter turns out to be extremely efficient, yielding decision trees with a single-digit number of decision nodes on 5 of the case studies.

We introduce a framework for approximate analysis of Markov decision processes (MDP) with bounded-, unbounded-, and infinite-horizon properties.

Statistical model checking (SMC) is a technique for analysis of probabilistic systems that may be (partially) unknown.

Assuming the support of the unknown transition function and a lower bound on the minimal transition probability are known in advance, we show that in MDPs consisting of a single end component, two combinations of guarantees on the parity and mean-payoff objectives can be achieved depending on how much memory one is willing to use.

In contrast to the usual understanding of probabilistic systems as stochastic processes, recently these systems have also been regarded as transformers of probabilities.
