depqbf - a solver for quantified boolean formulae
depqbf [options ...] [NUM] [FILE]
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.
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.
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.
