drat

A (parametrized) Rust SAT solver originally based on MiniSat

A distributed, parallelized (Map Reduce) wrapper around Apache RAT™ to allow it to complete on large code repositories of multiple file types where Apache RAT™ hangs forever.

drat2er: Proof Transformer for Propositional Logic

A drat repository for R Package releases including the R COBOL Data Integration (rcoboldi) and R Bitcoincharts.com API packages (rbitcoinchartsapi).

Verifies SAT solver output. Uses drat-trim proof checker for UNSAT instances.

Automatic CD by pushing packages to drat repos

Certified frame-first SAT middleware — decide structured regions (2-SAT · GF(2) parity · counting) before CDCL, and independently verify every verdict (model replay · DRAT). A research harness for where SAT hardness lives.

An almost-efficient implementation of a DRAT proof checker for validating unsatisfiability proofs of SAT instances in Rust.

A readable, self-checking CDCL SAT solver, preprocessor and encoding library. Every answer comes with a certificate.
