It includes rules to determine the color of an object, whether an object belongs to a person, whether an animal is both a herbivore and hunter, writing lists of animal names and characteristics, and displaying share prices as lines of asterisks. It is not yet good at recognising the relations between source code fragments and queries. The key feature of the GNU Prolog solver is the use 4. To use SWI-Prolog, a knowledgebase of facts and rules is created, connected Debugging Prolog Programs Graphical Debugger (gtrace): On CDF: run“xpce” instead of “prolog”. The program uses its identification rules to determine the animal that you have chosen. In particular, it ships with a wide range of interface libraries, pro- viding interfaces to other languages, databases, graphics and networking. Prolog Programming A First Course. g.
