Value Functions as Supermartingale Certificates

arXiv:2605.31524v1 Announce Type: new Abstract: Certification methods for stochastic systems provide sufficient proof rules, based on real-valued supermartingale certificates, to determine the almost-sure satisfaction of $\omega$-regular properties (and therefore of linear temporal logic) over general state spaces, encompassing both countably infinite and continuous state spaces. Conversely, reinforcement learning (RL) methods for $\omega$-regular tasks have received considerable attention, but they typically lack formal guarantees that the learned policy satisfies the specification, except po

Why this matters
Why now

This work is emerging now as the field of AI, particularly reinforcement learning, grapples with enabling robust and provably safe autonomous systems, moving beyond merely performance-driven metrics.

Why it’s important

It introduces formal certification methods that can guarantee the reliability and safety of reinforcement learning policies for complex stochastic systems, which is crucial for deployment in critical applications.

What changes

This research provides a theoretical framework for building verifiable AI systems, addressing the current lack of formal guarantees in learned policies and shifting towards more trustworthy AI deployments.
