This paper presents the first formal analysis of the official memory consistency model for the
NVIDIA PTX virtual ISA. Like other GPU memory models, the PTX memory model is weakly …

Automated program repair is an active research area. However, existing research focuses
mostly on imperative code, eg in Java. In this paper, we study the problem of repairing …

Alloy is a formal specification language, which despite featuring a simple syntax and
relational semantics, is very expressive and supports efficient automated specification …

Alloy is a well-known, formal, declarative language for modelling systems early in the
software development process. Currently, it uses the Kodkod library as a back-end for finite …

The steep learning curve associated with interactive theorem proving poses a significant
entry barrier for the learner. While the Alloy specification language has simplified the …

Alloy is both a formal language and a tool for software modeling. The language is basically
first order relational logic. The analyzer is based on instance finding: it tries to refute …

The multiplication of models, languages, APIs and tools for cloud and network configuration
management raises heterogeneity issues that can be tackled by introducing a reference …

We formalize a Hoare logic for the partial correctness of while programs in PVS and prove its
soundness and relative completeness. We use the PVS higher-order logic to define the …

With the growth of Cloud Computing comes the growth of the number of companies offering
different cloud services, which day after another causes overwhelming of the consumers …

In this thesis, the first steps in the developing of a counterexample finder for PVS based on
Kodkod is presented. A preliminary approach to the key feature of the proposed method, the …
