Computer programs are an indispensable part of many of the systems we rely upon in our daily lives, and the proper functioning and safety of these systems is of paramount importance. The development of methods that ensure program correctness is therefore a key challenge for computer scientists. This widely anticipated third edition of Verification of Sequential and Concurrent Programs provides a systematic exploration of one of the most common approaches to program verification, known as the "assertional" approach. Following the successful formula of previous editions, this approach is applied to deterministic and nondeterministic sequential programs of varying complexity, together with both parallel and distributed concurrent programs. The expanded content of this thorough new edition also includes coverage of the verification of object-oriented programs. For each class of programs, the authors introduce an operational semantics and proof systems for the verification of partial and total correctness, justified formally in corresponding soundness theorems. Case studies supplied throughout the book demonstrate the use of the proof systems to formally verify solutions to classical problems, such as sorting, manipulation of lists, producer/consumer and mutual exclusion. Topics and Features: Includes a thorough introductory section, familiarizing the reader with the basic concepts and notation used in the book, as well as the book’s structure Explains Hoare’s approach to program verification for while programs, providing a correctness proof of a program for partitioning an array (NEW) Concludes each chapter with exercises and bibliographic remarks for further reading Discusses recursive programs that extend deterministic programs by parameterless procedures and procedures with the call-by-value parameter mechanism, and provides a correctness proof of the quicksort program (NEW) Explores nondeterministic and distributed programs, presenting a verification method of distributed programs based on a transformation into nondeterministic ones Presents object-oriented programs, with a focus on the main characteristics of objects (NEW) Investigates parallel programs with shared variables and with synchronization Studies the issue of fairness in the framework of nondeterministic programs, using an approach based on the method of explicit schedulers Includes a Foreword by Professor Amir Pnueli This modern update of a classic, reader-friendly textbook is perfect for an introductory course on program verification for advanced undergraduate or graduate students, and may also be used as an introduction to operational semantics. Outlines for possible courses are suggested in the Preface to the book. This book is unique in addressing assertional verification of all essential classes of imperative programs: while programs, recursive programs, object-oriented programs, nondeterministic programs, parallel programs, and distributed programs.

Constraint programming is the fruit of several decades of research carried out in mathematical logic, automated deduction, operations research and arti?cial intelligence. The tools and programming languages arising from this research ?eldhaveenjoyedrealsuccessintheindustrialworldastheycontributetosolving hard combinatorial problems in diverse domains such as production planning, communication networks, robotics and bioinformatics. This volume contains the extended and reviewed versions of a selection of papers presented at the Joint ERCIM/CoLogNET International Workshop on Constraint Solving and Constraint Logic Programming (CSCLP2003), which was held from June 30 to July 2, 2003. The venue chosen for the seventh edition of this annual workshop was the Computer and Automation Research Institute of the Hungarian Academy of Sciences (MTA SZTAKI) in Budapest, Hungary. This institute is one of the 20 members of the Working Group on Constraints of the European Research Consortium for Informatics and Mathematics (ERCIM). For many participants this workshop provided the ?rst opportunity to visit their ERCIM partner in Budapest. CoLogNET is the European-funded network of excellence dedicated to s- porting and enhancing cooperation and research on all areas of computational logic, and continues the work done previously by the Compulog Net. In part- ular, the aim of the logic and constraint logic programming area of CoLogNET is to foster and support all research activities related to logic programming and constraint logic programming. The editors would like to take the opportunity and thank all the authors who submitted papers to this volume, as well as the reviewers for their helpful work.
