This book, with the CD-ROM included, is the documentation of a unique collaborative effort in evaluating formal methods for usage under industrial constraints: the major techniques for formally supported specification, design, and verification of large programs and complex systems are applied to a non-trivial and non-academic problem which is typical for industrial informal requirements specifications. The 21 papers included in the book, together with an introduction and competition report, were selected from 33 candidate solutions. This book comes with a CD-ROM containing, besides the printed papers, executable code, full definitions of all parts of the specifications, and detailed descriptions of foundational matters where appropriate.
