Approximate verification of the symbolic dynamics of Markov chains

M Agrawal, S Akshay, B Genest… - Journal of the ACM …, 2015 - dl.acm.org
A finite-state Markov chain M can be regarded as a linear transform operating on the set of
probability distributions over its node set. The iterative applications of M to an initial …

MDPs as distribution transformers: affine invariant synthesis for safety objectives

S Akshay, K Chatterjee, T Meggendorfer… - … Conference on Computer …, 2023 - Springer
Markov decision processes can be viewed as transformers of probability distributions. While
this view is useful from a practical standpoint to reason about trajectories of distributions …

Distributional reachability for markov decision processes: Theory and applications

Y Gao, A Abate, L Xie… - IEEE Transactions on …, 2023 - ieeexplore.ieee.org
We study distributional reachability for finite Markov decision processes (MDPs) from a
control theoretical perspective. Unlike standard probabilistic reachability notions, which are …

Distribution-based objectives for Markov decision processes

S Akshay, B Genest, N Vyas - Proceedings of the 33rd Annual ACM …, 2018 - dl.acm.org

This paper addresses a control problem for probabilistic models in the setting of Markov
decision processes (MDP). We are interested in the steady-state control problem which …

The orbit problem for parametric linear dynamical systems

C Baier, F Funke, S Jantsch, T Karimov… - arXiv preprint arXiv …, 2021 - arxiv.org
We study a parametric version of the Kannan-Lipton Orbit Problem for linear dynamical
systems. We show decidability in the case of one parameter and Skolem-hardness with two …

CTL Model Checking of MDPs over Distribution Spaces: Algorithms and Sampling-based Computations

Y Gao, KH Johansson, A Abate - Proceedings of the 27th ACM …, 2024 - dl.acm.org

decision processes (MDPs) over the space of their distributions. Instead of investigating …

[HTML][HTML] The complexity of synchronizing Markov decision processes

L Doyen, T Massart, M Shirmohammadi - Journal of Computer and System …, 2019 - Elsevier
We consider Markov decision processes (MDP) as generators of sequences of probability
distributions over states. A probability distribution is p-synchronizing if the probability mass is …
