Automating Event-B invariant proofs by rippling and proof patching

The use of formal method techniques can contribute to the production of more reliable and dependable systems. However, a common bottleneck for industrial adoption of such techniques is the needs for interactive proofs. We use a popular formal …

Formal reliability analysis of redundancy architectures

Reliability is a fundamental property for critical systems. A thorough evaluation of the reliability is required by the certification procedures in various application domains, and it is important to support the exploration of the space of the …

Extensional Petri net

Petri nets form a concurrent model for distributed and asynchronous systems. They are capable of modeling information flow in a closed system, but are generally not suitable for the study of compositionality. We address the issue of Petri net …

Automated mutual induction proof in separation logic

We present a deductive proof system to automatically prove separation logic entailments by mathematical induction. Our technique is called the mutual induction proof. It is an instance of the well-founded induction, a.k.a., Noetherian induction.

Hybrid statistical estimation of mutual information and its application to information flow

Analysis of a probabilistic system often requires to learn the joint probability distribution of its random variables. The computation of the exact distribution is usually an exhaustive precise analysis on all executions of the system. To avoid …

Über diese Zeitschrift

This journal aims to publish contributions at the junction of theory and practice. The objective is to disseminate applicable research. Thus new theoretical contributions are welcome where they are motivated by potential application; applications of existing formalisms are of interest if they show something novel about the approach or application.

The term "formal methods" has been applied to a range of notations, theories and tools. There is no doubt that some of these have already had a significant impact on practical applications of computing. Indeed, it is interesting to note that once something is adopted into practical use it is no longer thought of as a formal method. Apart from widely used notations such as those for syntax and state machines, there have been significant applications of specification notations, development methods and tools both for proving general results and for searching for specific conditions. However, the most profound and lasting influence of the formal approach is the way it has illuminated fundamental concepts like those of communication.

In this spirit, the principal aim of this journal is to promote the growth of computing science, to show its relation to practice and to stimulate applications of apposite formalisms to practical problems. One significant challenge is to show how a range of formal models can be related to each other.
