Description: Proof assistant based on first order natural deduction calculus
intended to reason about computable functionals, using minimal
rather than classical or intuitionistic logic. The main motivation
behind MINLOG is to exploit the proofsasprograms paradigm for
program development and program verification. Proofs are in fact
treated as first class objects which can be normalized. If a formula
is existential then its proof can be used for reading off an instance
of it, or changed appropriately for program development by proof
transformation. To this end MINLOG is equipped with tools to extract
functional programs directly from proof terms. This also applies to
nonconstructive proofs, using a refined Atranslation. The system
is supported by automatic proof search and normalization by
evaluation as an efficient term rewriting device.
.
Minlog can be used with ProofGeneral, which allows proofs to be
edited using emacs and xemacs. This requires the proofgeneralminlog
package to be installed.
