.TH "CRYPTOMINISAT" "1" "@VERSION@" "Mate Soos" "User Commands"
.SH "NAME"
cryptominisat \- conflict-driven SAT solver
.SH "SYNOPSIS"
.B cryptominisat
[\fIOPTIONS\fP] <\fIinput\-files\fP>
.SH "DESCRIPTION"
.PP
CryptoMiniSat is a SAT solver, solving problems given in CNF, or conjunctive
normal form. CryptoMiniSat retains much of the API of MiniSat, but
offers more versatility and better speed on many problems.
The program is a classical conflict-driven solver, with variable activities,
clause learning and clause deletion. It however incorporates a number of
advanced CNF simplification functionalities which should help the speed of
solving. Further, it incorporates some advanced memory-management features
that should help in getting the most out of modern CPU caches.
The input format is that of DIMACS CNF, i.e. a header of the form
p cnf VARS CLAUSES
where VARS is the number of variables, and CLAUSES is the number of clauses in
the problem. It then lists the set of clauses such as:
1 -2 0
which is equivalent to the 2-long clause "v1 OR NOT v2 = TRUE"

\fB\-\-gateeqlit\fP = \fI{0,1}\fP
Find equivalent literals using gates (default = 1).
.TP
\fB\-\-printgatedot\fP = \fI{0,1}\fP
Print gate structure regularly to the file 'gatesX.dot' (default = 0).
.SS "SQL"
.TP
\fB\-\-sql\fP = \fI{0,1,2}\fP
Write to SQL (default = 1). 0 means do not attempt to write to the database.
1 means to try to write to the database, but continue if the attempt fails. 2
means to abort if the database cannot be written.
.TP
\fB\-\-topnvars\fP = <\fInum\fP>
At every restart, dump data about the top N variables (default = 0). If set
to 0, nothing is dumped.
.TP
\fB\-\-dumptreevar\fP = \fI{0,1}\fP
Dump variance stats of the variables' decision and trail depths (default = 0).
.TP
\fB\-\-sqluser\fP = <\fIusername\fP>
The SQL user to connect with (default = cmsat_solver).
.TP
\fB\-\-sqlpass\fP = <\fIpassword\fP>
The SQL password to connect with.
.TP
\fB\-\-sqldb\fP = <\fIdatabase\fP>
The SQL database name (default = cmsat). The default is used by the PHP
system, so it is highly recommended.
.TP
\fB\-\-sqlserver\fP = <\fIhostname\fP>
The SQL server hostname or IP address (default = localhost).
.SS "MISCELLANEOUS"
.TP
\fB\-\-vivif\fP = \fI{0,1}\fP
Regularly execute clause vivification (default = 1).
.TP
\fB\-\-viviflongmaxm\fP = <\fInum\fP>
Maximum time in mega-bogoprops to spend on vivifying long irreducible clauses
by enqueueing and propagating (default = 20).
.TP
\fB\-\-viviffastmaxm\fP = <\fInum\fP>
Maximum time in mega-bogoprops to spend on vivifying long irreducible clauses
through watches, cache and stamps (default = 400).
.TP
\fB\-\-sortwatched\fP = \fI{0,1}\fP
Sort watches according to size (default = 1).
.TP
\fB\-\-renumber\fP = \fI{0,1}\fP
Renumber variables to increase CPU cache efficiency (default = 1).
.TP
\fB\-\-savemem\fP = \fI{0,1}\fP
Save memory by deallocating variable space after renumbering (default = 1).
This only works if renumbering is active.
.TP
\fB\-\-implicitmanip\fP = \fI{0,1}\fP
Subsume and strengthen implicit clauses with each other (default = 1).
.TP
\fB\-\-implsubsto\fP = <\fInum\fP>
The timeout of implicit subsumption in mega-bogoprops (default = 1900).
.TP
\fB\-\-burst\fP = <\fInum\fP>
The number of conflicts to do in burst search (default = 300).
.TP
\fB\-\-clearinter\fP = \fI{0,1}\fP
Interrupt threads cleanly, all the time (default = 0).
.TP
\fB\-\-zero\-exit\-status\fP = \fI{0,1}\fP
Exit with status zero in case the solving has finished without an issue.
.SH "EXIT STATUS"
.PP
The output is a solution, together with some timing information. If
\-\-zero\-exit\-status has not been specified, then the exit status is as
follows:
.IP 10
The problem is satisfiable.
.IP 15
The problem's satisfiability was not determined.
.IP 20
The problem is unsatisfiable.
