We present a method for symbolic model checking that can lead to significant time and memory savings for model-checking runs that fail, while occurring only a small overhead for model-checking runs that succeed. Our method discovers an error as soon as it cannot be prevented, which can be long before it actually occurs; for example, the violation of an invariant may become unpreventable many transitions before the invariant is violated.\r\nThe key observation is that “unpreventability” is a local property of a single module: an error is unpreventable in a module state if no environment can prevent it. Therefore, unpreventability is inexpensive to compute for each module, yet can save much work in the state exploration of the global, compound system. Based on different degrees of information available about the environment, we define and implement several notions of “unpreventability,” including the standard notion of uncontrollability from discrete-event control. We present experimental results for two examples, a distributed database protocol and a wireless communication protocol."}],"volume":1855,"publist_id":"70","intvolume":"      1855","year":"2000","acknowledgement":"This research was supported in part by the DARPA (NASA) grant NAG2-1214, the SRC contract 99-TJ-683.003, the MARCO grant 98-DT-660, the DARPA (MARCO) grant MDA972-99-1-0001, and the NSF CAREER award CCR-9501708.","author":[{"last_name":"De Alfaro","first_name":"Luca","full_name":"De Alfaro, Luca"},{"orcid":"0000−0002−2985−7724","full_name":"Henzinger, Thomas A","id":"40876CD8-F248-11E8-B48F-1D18A9856A87","last_name":"Henzinger","first_name":"Thomas A"},{"full_name":"Mang, Freddy","first_name":"Freddy","last_name":"Mang"}],"publication":"Proceedings of the 12th International Conference on Computer Aided Verification","doi":"10.1007/10722167_17","page":"186 - 201","publication_identifier":{"isbn":["9783540677703"]},"citation":{"short":"L.
