"This book has the possibility of being The Prolog Reference Book I would recommend the book for all the high quality examples alone. " Roy Freedman, Inductive Solutions, Inc. "This is the strongest book (in Prolog programming) on the market, by virtue of its coverage. The author hits a lot of the tried and true stuff in Prolog as well as some new departures. " Kevin Reilly, University of Alabama at Birmingham "The writing style is very clear and the explanations are logically presented. Students with no background in Prolog should be able to read the first two-thirds of this book and understand all of it. " Clint Smullen, University of Tennessee "The overall balance of the work is reasonable and appropriate. The organization is good, the examples and problems are excellent I believe it will be an excellent book for Prolog and AI courses. " Quang van Tran, Oklahoma State University "There seems to be hardly any programming problem which is not dealt with in one place or another. This should enable a very rich range of courses to be developed around the book. " Christopher Hogger, Imperial College, London
