Computation tree measurement language (CTML)

In this work, we present a formal language, CTML, to reason over probabilistic systems. CTML extends stochastic temporal logics in a way that it takes a real value as input and output a real value in the range of $${[0, \infty)}$$ [ 0 , ∞ ) , as …

How testing helps to diagnose proof failures

Applying deductive verification to formally prove that a program respects its formal specification is a very complex and time-consuming task due in particular to the lack of feedback in case of proof failures. Along with a non-compliance between …

Unifying separation logic and region logic to allow interoperability

Framing is important for specification and verification, especially in programs that mutate data structures with shared data, such as DAGs. Both separation logic and region logic are successful approaches to framing, with separation logic …

A UTP semantics for communicating processes with shared variables and its formal encoding in PVS

CSP# (communicating sequential programs) is a modelling language designed for specifying concurrent systems by integrating CSP-like compositional operators with sequential programs updating shared variables. In this work, we define an …

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.
