This volume contains the background texts for an IFIPState-of-the-Art Seminar on Formal Program Development, heldin early 1992 near Rio de Janeiro, Brazil.The book stems from work done by IFIP Working Group 2.1 onAlgorithmic Languages and Calculi. Since 1975, the WorkingGroup has increasingly focused on systematic approaches toprogramming and on appropriate concepts and notations tosupport such approaches. Today, the calculation of programsfrom specifications constitutes the central theme ofthegroup's work. Thus the core interests of the group are: - formal specification of solutions to...

The book constitutes the joint refereed proceedings of the 10th International Conference on Relational Methods in Computer Science, RelMiCS 2008, and the 5th International Workshop on Applications of Kleene Algebras, AKA 2008, held in Manchester, UK in April 2008. The 26 revised full papers presented together with 2 invited papers were carefully reviewed and selected from numerous submissions. The papers describe the calculus of relations and similar algebraic formalisms as methodological and conceptual tools with special focus on formal methods for software engineering, logics of programs...

This volume contains the proceedings of the 11th International Conference on RelationalMethodsinComputerScience(RelMiCS11)andthe6thInternational Conference on Applications of Kleene Algebra (AKA 6). The joint conference took place in Doha, Quatar, November 1-5, 2009. Its purpose was to bring - gether researchersfrom various subdisciplines of computer science, mathematics and related ?elds who use the calculus of relations and/or Kleene algebra as methodological and conceptual tools in their work. This conference is the joint continuation of two di?erent strands of meetings. The seminars of...
