Experimenting with SAT solvers in vampire
Paper i proceeding, 2014

Recently, a new reasoning framework, called AVATAR, integrating first-order theorem proving with SAT solving has been proposed. In this paper, we experimentally analyze the behavior of various SAT solvers within first-order proving. For doing so, we first integrate the Lingeling SAT solver within the firstorder theorem prover Vampire and compare the behavior of such an integration with Vampire using a less efficient SAT solver. Interestingly, our experiments on first-order problems show that using the best SAT solvers within AVATAR does not always give best performance. There are some problems that could be solved only by using a less efficient SAT solver than Lingeling. However, the integration of Lingeling with Vampire turned out to be the best when it came to solving most of the hard problems.
