Automatic Unbounded Verification of Alloy Specifications with Prover9
[article]
2012
arXiv
pre-print
Preserved Fulltext
In this paper we propose a translation from Alloy specifications to fork algebras (an extension of relation algebras with the same expressive power as relational logic) which enables their unbounded verification ...
This translation covers not only logic assertions, but also the structural aspects (namely type declarations), and was successfully implemented and applied to several examples. ...
The translation is thus defined by: translate * many(aggregate ⊲ definitions ⊲ uniform * )
Translating Alloy declarations to FA Besides translating Alloy formulas to FA we also need to express in this ...

We will examine how a constraint solver (the Alloy Analyzer) can be used to automatically check if refactorings, applied to a formal specification (written in Z), meet this requirement. ...
Refactorings are systematic changes made to programs, models or specifications in order to improve their structure without changing the externally observable behaviour. ...

As the compression proceeded, both translation/ rotation and the plastic deformation of solid grains occurred owing to an increase in physical contact between solid grains. ...
