Efficient Backward Reachability Using the Minkowski Difference of Constrained Zonotopes

no code implementations9 Jul 2022 Liren Yang, Hang Zhang, Jean-Baptiste Jeannin, Necmiye Ozay

This Minkowski difference needs to be represented as a constrained zonotope to enable subsequent computation, but, as we show, it is impossible to find a polynomial-sized representation for it in polynomial time.

Synthesis-guided Adversarial Scenario Generation for Gray-box Feedback Control Systems with Sensing Imperfections

no code implementations24 Jul 2021 Liren Yang, Necmiye Ozay

We develop an algorithm that searches for "adversarial scenarios", which can be thought of as the strategy for the adversary representing the noise and disturbances, that lead to safety violations.

Scalable Zonotopic Under-approximation of Backward Reachable Sets for Uncertain Linear Systems

no code implementations4 Jul 2021 Liren Yang, Necmiye Ozay

Zonotopes are widely used for over-approximating forward reachable sets of uncertain linear systems for verification purposes.
