A mathematical and logical foundation for the specification and development of interactive systems based on a model that describes systems in terms of their input/output behavior. Based on this model, the authors build a basic method, called FOCUS, that enables interactive systems to be described by characterizing their histories of message interaction. The book progresses from an introduction and guided tour of FOCUS through streams, specifications and their properties, and behavioral, interface, and conditional refinements.Ketil Stølen is the author of 'Specification and Development of Interactive Systems: Focus on Streams, Interfaces, and Refinement (Monographs in Computer Science)', published 2001 under ISBN 9780387950730 and ISBN 0387950737.
