» ACL2 Version 2.7 
A programming language in which you can model computer systems and a tool to help prove properties of those models. Available under GPL and runs on various platforms. Includes related download links. » Automated Reasoning Project
Web resource provided by research group. Includes access to software developed by the team, coverering such projects as FINDER (Finite Domain Enumerator), MaGIC (Matrix Generator for Implication Connectives) and Kripke (A theorem prover for the relevant » Bertrand
Bertrand solves sets of first-order predicate logic statements for satisfiability (consistency), validity, and equivalence. It also checks single statements for "logical truth" (tautology) and "logical falsity" (self-contradiction). » Church
Program understands the different types of lambda expressions, can extract lists of variables (both free and bound) and subterms, and can simplify complicated expressions. Uses Python. » CrocoPat: Simple and Efficient Relational Programming
CrocoPat manipulates relations of any arity, including graphs (which are binary relations). Its simple and expressive query and manipulation language is based on first-order predicate calculus. The implementation is based on the data structure binary deci » DC Proof Online
New proof-writing software to teach the fundamentals of logic and proof. Enables users/students to write error-free proofs by selecting rules of inference, axioms, etc. from convenient drop-down menus. Includes tutorial and exercises. » DELORES
A forward-chaining reasoning engine for defeasible logic, a less expressive but more efficient nonmonotonic logic. » Database of Existing Mechanized Reasoning Systems
A list (>50 entries) of automatic resolution provers (like Otter), interactive provers (like PVS) and other mechanized reasoning tools. » Gateway to Logic
A collection of web-based logic programs offering a number of logical functions: interactively or automatically build proofs, check theorems, and operate on propositional logic formulae. » Isabelle
A generic theorem proving environment developed at Cambridge University (Larry Paulson) and TU Munich (Tobias Nipkow). Includes logic, documentation and free download. » LOOM
A language and environment for constructing intelligent applications. It is a research project in the Artificial Intelligence research group at the University of Southern California's Information Sciences Institute. The goal of the project is to develop » LWB
Logics Workbench. » Logic Software from CSLI
By Jon Barwise and John Etchemendy. » MUltlog
Takes as input the specification of a finitely-valued first-order logic and produces a sequent calculus, a natural deduction system, and clause formation rules for this logic. » MUltseq
A generic sequent prover for propositional finitely-valued logics. » ModLeanTAP: Lean Tableau-based Deduction for Propositional Modal Logics
Lean Tableau-based Deduction for Propositional Modal Logics. By Bernhard Beckert. » PROTEIN
A PROver with a Theory Extension INterface. Theorem prover for first-order clause logic, written in ECRC's Prolog-dialect ECLiPSe. Free download, documentation. » PVS
The PVS Specification and Verification System. Available for Sparc machines with Solaris 2 and Intel x86 Machines with Linux compatible with Redhat 5 or later. Required is Emacs (version 19 or later), recommended LaTeX and Tcl/Tk. Download by FTP. » Paradox
A tool that processes first-order logic problems and tries to find finite-domain models for them; written by Koen Claessen and Niklas Sörensson. Haskell and C++; free download under GPL. » Proof General
Comprehensive Gnu-Emacs and XEmacs interface for several theorem provers including Coq, Isabelle, Lego, and Phox. » ProofPower
A suite of tools supporting specification and proof in Higher Order Logic (HOL) and in Z notation. » Spreadsheet Logic
Free Microsoft Excel add-in for processing and evaluating logic in your spreadhseet. » SwitchMin Digital Circuit Minimizer
Tool for minimizing boolean logic functions. » The Coq Project
Deals with effectively machine-checked formal mathematics. In practice, this includes the study of mathematical formalisms well-suited for implementations, the implementations themselves and the use of these for various applications. Focuses on software c » Tree Proof Generator
An implementation of the semantic tableaux method for classical propositional and predicate logic, written in JavaScript/DOM. » VeriFun
A semi-automated system for the verification of statements about programs written in a functional programming language. The system is capable of following fully-automated routines for theorem proving and hypotheses formation, as well as operating interact » Visual Turing
A graphical IDE for creating, running and debugging Turing machines. Freeware for Windows 95/98/NT/2000. » WinKE
An interactive proof assistant based on analytic tableaux, and designed for the teaching of deductive reasoning. Ordering information is available at this site, as are academic papers on the design of the software. » j'Imp Theorem Prover
An automatic theorem prover based on set of support and ordered resolution for first-order logic. j'Imp is part of the Orbital library. This library is a Java class providing object-oriented representations and algorithms for logic, mathematics, and arti » llprover
A linear logic prover that searches a cut-free proof for the given two-sided sequent of first-order linear logic. |
