Kurzfassung englisch:
We present the tool qbf2epr which translates quantified Boolean formulas (QBF) to formulas in effectively propositional logic (EPR). The decision problem of QBF is the prototypical problem for PSPACE, whereas EPR is NEXPTIME-complete. Thus QBF is embedded in a formalism, which is potentially more succinct. The motivation for this work is twofold. On the one hand, our tool generates challenging benchmarks for EPR solvers.
On the other hand, we are interested in how EPR solvers perform compared to QBF solvers and if there are techniques implemented in EPR solvers which would also be valuable in QBF solvers and vice versa. Furthermore, we provide an improved encoding of QBF in EPR based on dependency schemes which are a powerful concept in QBF solving.
