QBV , the Quantified Boolean Valdidator, is a tool that validates certificates (proofs) of QBF Solvers. For reference we have implemented the following suite of QBF Validation tools:
-
squolem , a Skolemization-based QBF solver that generates certificates.
-
QBV , a certificate validator.
-
QBFi , a QBF problem inverter.
All of them are available for Download.
The certificate format the we defined makes use of
Skolem-functions for certificates of validity and Q-Resolution
for certificates of invalidity.
For a performance comparison, see Statistics.

QBV or squolem , contact
