We present new and more efficient decision procedures for intuitionistic propositional logic. They themselves are given by (non-formal) constructive proofs. We take one of them to demonstrate that constructive type theory can be used in practice to develop a real, efficient, but error-free proof searcher. This was done by formally proving the decidability of intuitionistic propositional logic in Coq; the proof searcher was automatically extracted.""" flags: light-uninstall url { src: "https://github.com/coq-contribs/ipc/archive/v8.7.0.tar.gz" checksum: "md5=2decb894bffbd256b5b0e6d042da2ae1" }
