LISP is popularly thought of as the lingua franca of Artificial Intelligence, and this book demonstrates how to use LISP in AI, and particularly the areas of simulation and modelling. There are two main parts to the book: part one introduces LISP, shows its differences from other languages, and gives a complete tutorial in the language. Part two explains why LISP is such a useful language to use in systems modelling and simulation. After providing background to AI techniques, the book shows how to simulate both simple and real-life queueing situations. Throughout the book, complete and tested LISP programs are presented that can readily be entered, tested and modified on a variety of popular microcomputers.
