Formal Verification of 800 Genetically Constructed Automata Programs: A Case Study

摘要

Engineering of mission critical software requires a program to be verified that it satisfies a number of properties. This is often done using model checking. However, construction of a program model to be verified and analyzing counterexamples is not an easy task. This can be made easier with the automata-based programming paradigm. There exist some cases when there are many programs to verify and it is impossible to construct a precise enough finite-state model of the environment. We present an approach for automata program verification under such conditions. Our case study is based on 800 automata programs which solve a simple path-planning problem. As a result, we verified that at least 231 of them are provably correct.
