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 descrip-
tion 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.
