Software testing is used to improve software quality by finding fault in the software. To verify the software behavior, testers require test oracle, which is a reliable source of expected software behavior and provides outputs for any input specified in the software specifications and a comparator to verify actual results generated by the software. While test automation requires automated oracl...

RRL (Rewrite Rule Laboratory) was originally developed as an environment for experimenting with automated reasoning algorithms for equational logic based on rewrite techniques. It has now matured into a full-edged theorem prover which has been used to solve hard and challenging mathematical problems in automated reasoning literature as well as a research tool for investigating the use of formal...

Fixture design is crucial part of manufacturing process. Fixture design is a critical design activity process, in which automation plays an integral role in linking computer-aided design (CAD) and computer-aided manufacturing (CAD). This paper presents a literature review in computer aided fixture design (CAFD) in terms of automation and optimization techniques over the past decades. First, the...

Relation algebras provide abstract equational axioms for the calculus of binary relations. They name an established area of mathematics and have found numerous applications in computing. We prove more than hundred theorems of relation algebras with off-the-shelf automated theorem provers. They form a basic calculus from which more advanced applications can be explored. We also present two autom...

Event-B is a formal method used to do Model Driven Engineering certified by theorem proving. We propose a pattern to handle duration over a predicate in this method which originally does not have particular tool to specify and reason about real-time properties.

In this paper we describe investigations into the use of automatic theorem proving technology in the refutation of proof obligations. Specifically, we discuss the use of resolution based theorem proving and model checking to find false obligations and counterexamples. These techniques can be used as basis of an automatic method for finding faults in design during the formal development of softw...
