Logic is now widely recognized to be one of the foundational disciplines of computing with applications reaching almost every aspect of the subject, from software engineering and hardware to programming languages and artificial intelligence. The Handbook of Logic in Artificial Intelligence andLogic Programming is a multi-volume work covering all major areas of application of logic to AI and logic programming. Each volume features a combination of authoritative exposition, comprehensive survey, and fundamental research exploring the underlying themes in various areas. Volumes 1 and 2present the logical foundations and deduction methodologies extensively used in AI. Volumes 3 and 4 cover reasoning, and Volume 5 details logic programming. The chapters, which in many cases are of monograph length and scope, emphasize possible unifying themes and are written by internationallyknown researchers. Students and researchers of artificial intelligence, computer science, and logic will find this landmark reference invaluable to their work.
