Verification of Patterns

The software patterns provide building blocks to the design and implementation of a software system, and try to make the software engineering to progress from experience to science. The software patterns were made famous because of the introduction as the design patterns. After that, patterns have been researched and developed widely and rapidly. The series of books of pattern-oriented software architecture should be marked in the development of software patterns. As mentioned in these books, formalization of patterns and an intermediate pattern language are needed and should be developed in the future of patterns. So, in this book, we formalize software patterns according to the categories of the series of books of pattern-oriented software architecture, and verify the correctness of patterns based on truly concurrent process algebra. In one aspect, patterns are formalized and verified; in the other aspect, truly concurrent process algebra can play a role of an intermediate pattern language for its rigorous theory.
