LINQ to Z3, The World’s Fasted Theorem Prover
Microsoft Research claims that Z3 is the world’s fastest theorem prover. Z3 is designed to be a low-level tool for other applications, it is not meant to stand-alone. With its host of theorem provers, it is used by numerous projects including Spec#/Boogie, Pex, Yogi, Vigilante, SLAM, F7, SAGE, VS3, FORMULA, and HAVOC. With Bart De Smet’s LINQ to Z3, using this tool becomes embarrassingly easy.
