%X This paper proposes the Agreement Problem Protocol
Verification Environment (APPROVE) for the automated formal
verification of novel solutions to agreement problems in
group communication systems. Agreement problems are
characterized by the need for a group of processes to agree
on a proposed value and are exemplified by group membership,
consensus and fault\-tolerance scenarios. Due to their
fundamental role, it is important that the correctness of
new agreement algorithms be verified formally. In the past,
the application of manual proof methods has been met with
varying degrees of success, suggesting the need for a less
error prone automated approach. An observation concerning
previous proofs is that often a significant amount of effort
is invested in modeling themes common to all such proofs,
albeit using different formalisms. Thus, the APPROVE project
aims to address these issues, its envisaged culmination
being a usable software framework that exploits model
re\-use wherever possible.
