Isabelle is a generic proof assistant. It allows mathematical formulas to be expressed in a formal language and provides tools for proving those formulas in a logical calculus. Isabelle is developed at University of Cambridge (Larry Paulson) and Technische Universität München (Tobias Nipkow). See the Isabelle overview for a brief introduction. Now available: Isabelle2008 Some notable improvements: * HOL: significant speedup of Metis prover; proper support for multithreading. * HOL: new version of primrec command supporting type-inference and local theory targets. * HOL: improved support for termination proofs of recursive function definitions. * New local theory targets for class instantiation and overloading. * Support for named dynamic lists of theorems.
This page represents the current state of an ongoing effort to collect information about existing automated reasoning systems. One objective is to provide concise useful information for people who have need for such a system and don't want to `roll their own'. Another objective is to provide a single place where information about existing systems can be accessed, thus providing an overview of the state of the art.
A Special Issue on Formal Proof
Using computers in proofs both extends mathematics with new results and creates new mathematical questions about the nature and technique of such proofs. This special issue features a collection of articles by practitioners and theorists of such formal proofs which explore both aspects.

The "International Journal of Critical Computer-Based Systems" (IJCCBS) is a quarterly research journal by Inderscience Publishers. It focuses on engineering and verification of complex computer-based systems (where complex means large, distributed and heterogeneous) in critical applications, with special emphasis on model-based approaches and industrial case-studies. Critical computer-based systems include real-time control, fly/brake-by-wire, on-line transactional and web servers, biomedical apparels, networked devices for telecommunications, environmental monitoring, infrastructure protection, etc.
This document contains some pointers to information on Formal Methods, useful for mathematically describing and reasoning about computer-based systems, available around the world on the World Wide Web (WWW). Formal methods are a fault avoidance technique that help in the reduction of errors introduced into a system, particularly at the earlier stages of design. They complement fault removal techniques like testing.
