The third outcome usually manifests itself in a space-out, time-out, or one component of the verification tool giving up; in all of these failing cases, significant computation is performed by the verification tool before the failure, but no result is reported. We propose to reformulate the model-checking problem as follows, in order to have the verification tool report a summary of the performed work even in case of failure: given a program and a specification, the model checker returns a condition Ψ - usually a state predicate - such that the program satisfies the specification under the condition Ψ - that is, as long as the program does not leave the states in which Ψ is satisfied. In our experiments, we investigated as one major application of conditional model checking the sequential combination of model checkers with information passing. We give the condition that one model checker produces, as input to a second conditional model checker, such that the verification problem for the second is restricted to the part of the state space that is not covered by the condition, i.e., the second model checker works on the problems that the first model checker could not solve. Our experiments demonstrate that repeated application of conditional model checkers, passing information from one model checker to the next, can significantly improve the verification results and performance, i.e., we can now verify programs that we could not verify before.","lang":"eng"}],"author":[{"full_name":"Beyer, Dirk","last_name":"Beyer","first_name":"Dirk"},{"orcid":"0000−0002−2985−7724","last_name":"Henzinger","full_name":"Henzinger, Thomas A","id":"40876CD8-F248-11E8-B48F-1D18A9856A87","first_name":"Thomas A"},{"first_name":"Mehmet","full_name":"Keremoglu, Mehmet","last_name":"Keremoglu"},{"first_name":"Philipp","full_name":"Wendler, Philipp","last_name":"Wendler"}],"title":"Conditional model checking: A technique to pass information between verifiers","department":[{"_id":"ToHe"}],"language":[{"iso":"eng"}],"user_id":"3E5EF7F0-F248-11E8-B48F-1D18A9856A87","year":"2012","scopus_import":1,"date_updated":"2021-01-12T06:50:18Z","quality_controlled":"1","oa_version":"Preprint","day":"01","type":"conference","_id":"1384","ec_funded":1,"publisher":"ACM","date_published":"2012-11-01T00:00:00Z","doi":"10.1145/2393596.2393664","publist_id":"5826","date_created":"2018-12-11T11:51:42Z","month":"11","article_number":"57"}
