Varisat is a CDCL based SAT solver written in Rust. Given a boolean formula in conjunctive normal form, 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) and as a command line solver (
varisat-cli on crates.io).
The MIT/Apache-2.0 dual licensed source code is available on GitHub.
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.
The command line solver is also available as a pre-compiled binary for Linux and Windows.
The internal APIs are documented using rustdoc. It can be generated using
cargo doc --document-private-items --all --exclude varisat-cli or viewed online (master).
A version of the user manual built from the master branch is also available.
You can also read a series of blog posts about the development of varisat.
