The recent years have brought a number of advances in the development of infinitestate verification, using techniques such as symbolic or parameterized representations, symmetry reductions, abstractions, constraint-based approaches, combinations of model checking and theorem proving. The active state of research on this topic provides a good time-point to increase impact by bringing together leading scientists and practitioners from these individual approaches.
The NATO Advanced Research Workshop “Verification of Infinite State Systems with Applications to Security VISSAS 2005”, which was held in Timişoara, România, on March 17–22, 2005, aimed to give an overview of the state of the art and of the current research directions, and to provide a forum for researchers interested in the development of mathematical techniques for the analysis of infinite state systems.
The success of this workshop was not only due to the excellent lectures, but also due to the participants taking part in the discussions at the workshop, the exchange of different views, and the recognition of the similarity of a number of different view points. These were some of the most important contributions of the workshop.
It is our pleasure to thank here all the people who helped to make the workshop a full success. This includes the lecturers, the participants, and the members of the organizing staff. Special thanks go to IeAT, the host of our workshop.
Finally, we would like to acknowledge the financial support received from NATO, and the excellent cooperation with IOS Press in the preparation of this volume.
