This paper focused on the safety verification of the multithreaded programs for mobile crowdsourcing networks. A novel algorithm was proposed to find a way to apply IC3, which is typically the fastest algorithm for SAT-based finite state model checking, in a very clever manner to solve the safety problem of multithreaded programs. By computing a series of overapproximation reachability, the safety properties can be verified by the SAT-based model checking algorithms. The results show that the new algorithm outperforms all the recently published works, especially on memory consumption (an advantage that comes from IC3).
