Equational prover
Template:Short description Template:About
Template:Article for deletion/dated Template:Third-party EQP (Equational prover) is an automated theorem proving program for equational logic, developed by the Mathematics and Computer Science Division of the Argonne National Laboratory. It was one of the provers used for solving a longstanding problem posed by Herbert Robbins, namely, whether all Robbins algebras are Boolean algebras. A simplified version of the EQP proof was later published by Bernd Dahn.<ref>Template:Cite journal</ref>
