Integration of Interactive and Automatic Provers

Interactive and resolution based automatic provers have both been used widely. Interactive provers offer users expressive formalisms and flexibility and are suitable for proving theorems of any user defined logics. However, they provide limited automation. In comparison, resolution based automatic provers provide automation, but only allow first order logic with equality. I am investigating combining the two types of provers through integrating an interactive prover Isabelle and a resolution based automatic prover Vampire. This paper gives an overview of the integration and describes the techniques used in it. It also lists some experimental results.
