Coverability for Parallel Programs
 Turoňová, Lenka ; Vojnar, Tomáš (referee) ; Holík, Lukáš (advisor)
This work is focusing on automatic verification of systems with parallel running processes. We discuss the existing methods and certain possibilities of optimizing them. Existing techniques are essentially based on finding an inductive invariant (for instance using a variant of counterexample-guided abstract refinement (CEGAR)). The effectiveness of these methods depends on the size of the invariant. In this thesis, we explored the possibility of improving the methods by focusing on finding invariants of minimal size. We implemented a tool that facilitates exploring the space of invariants of the system under scrutiny. Our experimental results show that many practical existing systems indeed have invariants that are much smaller than what can be found by the existing methods. The conjectures and the results of the work will serve as a basis of future research of an efficient method for finding small invariants of parallel systems.
