NAME

       minisat - fast and lightweight SAT solver

SYNOPSIS

       minisat [options] input-file result-output-file

       minisat  takes  as  input  a plain or gzipped DIMACS formatted file. The satisfiability of
       this input problem is indicated both via standard output and the return value.

DESCRIPTION

       This manual page documents briefly the minisat command. MiniSat is a  minimalistic,  open-
       source  SAT  solver,  developed to help researchers and developers alike to get started on
       SAT. Winning all the industrial categories of the SAT 2005 competition, MiniSat is a  good
       starting point both for future research in SAT, and for applications using SAT.

       Despite  the  NP completeness of the satisfiability problem of Boolean formulas (SAT), SAT
       solvers are often able to decide this problem in a reasonable time frame. As all other  NP
       complete problems are reducible to SAT, the solvers have become a general purpose tool for
       this class of problems.

OPTIONS

       --help, --help-verb Show (verbose) summary of options.

       -pre, -no-pre
              Enable (default) or disable preprocessing.

       -verb {0,1,2}
              Set the verbosity of informational output (set to 0 for silent, defaults to 1)

       -cpu-lim <unsigned>
              Set a limit on CPU time (seconds, defaults to 2147483647).

       -mem-lim <unsigned>
              Set a limit on memory usage (MB, defaults to 2147483647).

       -dimacs <output-file>
              Print (possibly preprocessed) input problem in DIMACS format and stop.

       -luby, -no-luby
              Enable (default) or disable the Luby restart sequence.

       -rnd-init, -no-rnd-init
              Randomize the initial activity values (defaults to off).

       -gc-frac <double>
              The fraction of wasted memory allowed before  a  garbage  collection  is  triggered
              (non-negative, defaults to 0.2).

       -rinc <double>

       -var-decay <double>
              Variable activity decay factor (0 <= value <= 1, defaults to 0.95).

       -cla-decay <double>
              Clause activity decay factor (0 <= value <= 1, defaults to 0.999).

       -rnd-freq <double>
              The  frequency  with which the decision heuristic tries to choose a random variable
              (0 <= value <= 1, defaults to 0).

       -rnd-seed <double>
              Random seed  for random variable selection (non-negative, defaults to 9.16483e+07).

       -phase-saving {0,1,2}
              Controls the level of phase saving (0=none, 1=limited, 2=full, defaults to 2).

       -ccmin-mode {0,1,2}
              Controls conflict clause minimization (0=none, 1=basic, 2=deep, defaults to 2)

       -rfirst <int>
              The base restart interval (positive, defaults to 100).

       -rcheck, -no-rcheck
              Enable (costly) or disable (default) checking for redundant clauses.

       -asymm, -no-asymm
              Shrink clauses by asymmetric branching (disabled by default).

       -elim, -no-elim
              Perform variable elimination (enabled by default).

       -simp-gc-frac <double>
              The fraction of wasted memory allowed before  a  garbage  collection  is  triggered
              during simplification (non-negative, defaults to 0.5).

       -sub-lim <int>
              Do  not  check if subsumption against a clause larger than this value (-1 <= value,
              defaults to 1000). -1 means no limit.

       -cl-lim <int>
              Variables are not eliminated if they produce a resolvent with a length  above  this
              limit (-1 <= value, defaults to 20). -1 means no limit.

       -grow <int>
              Number  of  additional  clauses that may be introduced when eliminating a variable.
              Defaults to 0.

EXIT CODES

       0 if parsing the command line options fails, usage information is requested, or output  of
       the  input  problem  in DIMACS format succeeds.  1 if interrupted by SIGINT or if an input
       file cannot be read, 3 if parsing the input fails, 10 if  found  satisfiable,  and  20  if
       found unsatisfiable.
