![](https://img.shields.io/crates/l/varisat.svg)

Varisat is a [CDCL][cdcl] based SAT solver written in rust. Given a boolean

formula in [conjunctive normal form][cnf], it either finds a variable

assignment that makes the formula true or finds a proof that this is

impossible.

Varisat is available as a rust library ([`varisat` on

crates.io][crate-varisat]) and as a command line solver ([`varisat-cli` on

crates.io][crate-varisat-cli]).

## Installation

Varisat is available using rust's package manager cargo. The command line

solver can be installed or updated using `cargo install --force varisat-cli`.

Cargo can be installed using [rustup](https://rustup.rs/).

The command line solver is also available as a [pre-compiled binary][releases]

for Linux and Windows.
