In this paper we present an extension to the proof system underlying VeriPB that allows the use of auxiliary preorder variables for dominance-based redundancy. This leads to substantial improvements in proof logging and checking for symmetry breaking.
The website for our new WWTF-funded project Verifying Without Loss of Generality is now online.
This new WWTF-funded project, directed by myself and Georg Weissenbacher, targets a closer integration between engineer insight and hardware model checking tools through reasoning without loss of generality.
In this paper I present a new proof system that completely bypasses the problems caused by interference in the context of DRAT-like proofs in SAT solving.
