Abstract:Abstract/ and its variants have been the prominent approaches to safety model checking in recent years. Compared to the previous model-checking algorithms like (Bounded Model Checking) and (Interpolation Model Checking), / is attractive due to its completeness (vs. ) and scalability (vs. ). / maintains an over-approximate state sequence for proving the correctness. Although the sequence refinement methodology is known to be crucial for performance, the literature lacks a systematic analysis of the problem. W… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
