Introduction
Overview
The term Computer-Aided Verification refers to theory and practice of computer-supported formal analysis methods for both hardware and software systems. Likewise, it is the name of an annual academic conference on that topic. The modeling and verification of such systems is an important issue. In particular, safety-critical systems are ones in which errors can be disastrous: loss of life, major financial losses, etc. Techniques to safeguard against such scenarios are essential for such systems. Testing can identify problems, especially if done in a rigorous fashion, but is generally not sufficient to guarantee a satisfactory level of quality. Formal methods, on the other hand, offer techniques ranging from the description of requirements in a formal notation to allow for rigorous reasoning about them, to techniques for automatic verification of software. Due to the complexity of these approaches and the systems they are applied to, automated computer support is indispensable.
The goal of this seminar is to give an overview of the related research activities of the MOVES group. It covers several areas of computer science to which computed-aided verification techniques are central, and which represent the research fields of the respective supervisors. Each area features a number of topics which are described in a scientific journal or conference article. These research articles are the basis on which students have to prepare their report and presentation. The following list gives an overview of the areas that will be covered.
