Abstract

The DAWN approach allows to model and verify distributed algorithms in an intuitive way. At a first glance, a DAWN proof may appear to be informal. In this paper, we argue that DAWN proofs are formal and can be checked for correctness fully automatically by automated theorem provers. The basic technique are proof rules which generate proof obligations. For the definition of the proof rules we adopt assertions and we introduce conflict formulas for algebraic Petri nets. Experiments show that the generated proof obligations can be automatically checked by theorem provers.
