The Checkers Proof Certifier

Participants : Tomer Libal, Giselle Reis, Hichem Chihani.

We presented a system description [29] of the Checkers proof certifier, which implements some of the theoretical ideas developed in the ProofCert project. This version of the system is capable of certifying a subset of the E-Prover superposition theorem prover. The system is mainly written in $\lambda$Prolog with a proof importing module written in Ocaml. The system is designed to allow modularity when designing the semantical translations of proof systems. For this capacity, the system supports, J. A. Robinson's resolution and the paramodulation technique of G. Robinson and L. Wos. On top of that, minimal support for some inference rules of the E-Prover was added.
