Simple type theory, also known as higher-order logic, is a natural extension of first-order
logic which is simple, elegant, highly expressive, and practical. This paper surveys the …

Computers arechanging the way wethink. Of course, nearly all desk-workers have access to
computers and use them to email their colleagues, search the Web for information and …

Heterogeneous specification becomes more and more important because complex systems
are often specified using multiple viewpoints, involving multiple formalisms (see Fig. 1) …

This paper proposes a new optimization technique called the African Buffalo Optimization.
The African Buffalo Optimization (ABO) draws its inspiration from the behavior of African …

ACL2 is a reimplemented extended version of RS Boyer and JS Moore's (1979; 1988)
Nqthm and M. Kaufmann's (1988) Pc-Nqthm, intended for large scale verification projects …

The basic motivation of this work is to make formal theory developments with machine-
checked proofs accessible to a broader audience. Our particular approach is centered …

This document provides an introductory example, a tutorial, and a compact reference to the
PVS verification system. It is intended to provide enough information to get you started using …

This book discusses the use of the real numbers in theorem proving. Typ ically, theorem
provers only support a few'discrete'datatypes such as the natural numbers. However the …

A specification language used in the context of an effective theorem prover can provide
novel features that enhance precision and expressiveness. In particular, type checking for …

This report was prepared to supplement a forthcoming chapter on formal methods in the FAA
Digital Systems Validation Handbook1. Its purpose is to outline the technical basis for formal …
