$S^3$: A Smooth Simulation Surrogate for Optimizing Discrete Abstractions of Dynamical Systems

Intelligent systems are increasingly deployed in safety-critical settings with black-box controllers, including neural networks. The properties and behaviors of these end-to-end systems can be studied with abstraction-based methods that replace them with simpler finite models. Constructing such abstractions requires ba...

A Pragmatic Guide to Building Conservative Discrete Abstractions of Cyber-Physical Systems

This tutorial presents a pragmatic, conservative-by-construction workflow for building discrete abstractions of closed-loop dynamical systems and demonstrates the end-to-end pipeline on three case studies and reports how design choices affect abstraction structure, runtime, and verification outcomes.
