NAME

       depqbf - a solver for quantified boolean formulae

SYNOPSIS

       depqbf [options ...] [NUM] [FILE]

DESCRIPTION

       depqbf  is  a  search-based  solver  for  quantified  boolean  formulae  (QBF)  in  prenex
       conjunctive normal form. It is based on the DPLL algorithm for  QBF  with  conflict-driven
       clause  and solution-driven cube learning. By analyzing the structure of a formula, DepQBF
       tries to identify independent  variables.  In  addition  to  other  benefits,  this  often
       increases  freedom for decision making. See also the JSAT system description of DepQBF 0.1
       from QBFEVAL'10 for references and a brief outline of the idea.

       depqbf reads QBF formulas in QDIMACS format. If FILE is not given, it reads its input from
       stdin. It complies with input/output standards as required by QBFEVAL'10.

OPTIONS

       depqbf accepts the following options:

       -h, --help
              Print usage information.

       --version
              Print version.

       --pretty-print
              Only parse and print formula.

       -v     Increase verbosity incrementally.

       NUM    Optional: time-out after NUM seconds.

       FILE   Optional: read input from FILE.

EXIT STATUS

       The  exit  status  is 10 if the QBF formula given as input is satisfiable, and 20 if it is
       unsatisfiable; any other exit code indicates that the formula was not solved.
