Logic, Programming and Prolog

The use of logic as the basis for program development is motivated by the possibilities it offers for achieving greater program correctness. PROLOG is a high-level programming language based on the concept of logic. This text offers a concise treatment of the theory of logic programming and a practical, problem-solving approach to its applications. It introduces major new developments in a continually evolving field, including topics such as concurrency, equational logic programming and constraint logic programming. The text has been revised to include a chapter on the negation problem, normal logic programs, completion semantics and SLDNF - resolution for Stratified Programs and Non-stratified Programs. Additional changes can be found within chapter 14, with its new focus on constraints; constraint domains and concurrent constraint programming.
