Abstract

We present a method—called quantifier tree reconstruction—that allows to efficiently recover ex-post a portion of the internal structure of QBF instances which was hidden as a consequence of the cast to prenex normal form. Means to profit from a quantifier tree are presented for all the main families of QBF solvers. Experiments on QBFLIB instances are also reported.
