Computer programs are becoming more and more part of systems that we use to rely on in our daily lives. The proper functioning and safety of these systems is of paramount importance. A major challenger for computer science is to develop methods that ensure program correctness. This textbook provides a structured introduction to program verification using an assertional approach - so named because it relies on the use of assertions that are attached to program control points. Sequential programs in the form of deterministic and nondeterministic programs, and concurrent programs in the form of parallel and distributed programs are considered within the context of their partial and total correctness. The use of these proof systems is demonstrated with the help of case studies. In particular solutions to classical problems such as mutual exclusion are formally verified. Each chapter concludes with exercises and bibliographic remarks for further reading. As a result, this text will be appropriate for either an introductory course on program verification for upper division of undergraduate studies or for graduate studies. It can also be used as an introduction to operational semantics. Outlines of possible courses are presented in the preface of the book.

HIS BOOK CONTAINS a most comprehensive text that presents syntax-directed and compositional methods for the formal veri?- T cation of programs. The approach is not language-bounded in the sense that it covers a large variety of programming models and features that appear in most modern programming languages. It covers the classes of - quential and parallel, deterministic and non-deterministic, distributed and object-oriented programs. For each of the classes it presents the various c- teria of correctness that are relevant for these classes, such as interference freedom, deadlock freedom, and appropriate notions of liveness for parallel programs. Also, special proof rules appropriate for each class of programs are presented. In spite of this diversity due to the rich program classes cons- ered, there exist a uniform underlying theory of veri?cation which is synt- oriented and promotes compositional approaches to veri?cation, leading to scalability of the methods. The text strikes the proper balance between mathematical rigor and - dactic introduction of increasingly complex rules in an incremental manner, adequately supported by state-of-the-art examples. As a result it can serve as a textbook for a variety of courses on di?erent levels and varying durations. It can also serve as a reference book for researchers in the theory of veri?- tion, in particular since it contains much material that never before appeared in book form. This is specially true for the treatment of object-oriented p- grams which is entirely novel and is strikingly elegant.
Verification of Sequential and Concurrent Programs
This book provides a structured introduction to the verification of sequen tial and concurrent programs. It thus belongs to the area of programming languages but at the same time it is firmly based on mathematical logic. In logic one usually studies fixed syntactic or semantic objects. This is not necessarily the case in the area of program verification. The objects studied here, namely programs, do not have a standard syntax, their semantics can be defined in many different ways, and several approaches to their verification can be contemplated. These differences lead to various difficult design decisions. Even though we restrict our attention here to one programming style - imperative pro gramming - we are still confronted with a veritable cornucopia of pro gramming constructs from which an appropriate selection has to be made. Having studied some of these constructs separately does not yet imply that we understand their combined effect.
