Kleene algebra with tests (KAT) is an equational system for program verification that combines Kleene algebra (KA) with Boolean algebra. KAT has been applied successfully in various low-level verification tasks involving communication protocols, basic safety analysis, source-to-source program transformation, concurrency control, compiler optimization, and static analysis. The system subsumes Hoare logic and is deductively complete for partial correctness over relational models.
KAT-ML is an interactive theorem prover for Kleene algebra with tests. The system is designed to reflect the natural style of reasoning with KAT that one finds in the literature. It is available for several platforms.
