SAT solver written in Rust

Varisat

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).

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.

The command line solver is also available as a pre-compiled binary for Linux and Windows.
