Amzi! inc. Adventure in Prolog

You have probably heard most of the terms before, but in Prolog they don’t necessarily mean what you think they mean. Here are two example predicates.

Go back to the edit window and add the line. You should now be able to create and edit source files for Prolog, and be able to load and use them from a Prolog listener. Puzzle is only called from goto for this reason. This is done automatically by Prolog. This leads to a very declarative style of programming. Your mission is to find the Nani. Loading the source code in the Listener is called consulting.

You can also consult a Prolog source file directly from the listener prompt like this. This message is followed by the typical listener prompt.


As with any language, the best way to learn Prolog is to use it. You can go to’ ,nl, write ‘other rooms, look at your surroundings, look in things’ ,nl, write ‘take things, drop things, eat things, inventory the’ ,nl, write ‘things you have, and turn things on and off. Your persona as the adventurer is that of a three year old girl.

A programmer needs to do things that have nothing to do tuyorial logic, such as read and write terms. You are in the kitchen.

As you develop your own version you can of course change the game to reflect your own ideas of adventure. This appendix contains sample versions of the four programs described in the book.

By itself, however, a logical theorem prover is not a practical programming tool. This book is designed to be used with a Prolog listener, and will guide you through the building of four applications.

The arity is the fixed number of arguments attributes, fields the predicate has. For the most part, the programmer is freed from having to worry about control structures and transfer of control mechanisms. The following example illustrates a Prolog program that prints a report of all the known mortals.


The terrifying obstacle between you and success is a dark room. Eclipse IDE, first create a project for your source files. Hello World yes You are now ready to learn Prolog. As such, it approaches the ideal of executable program specifications.

A programmer also needs to manipulate the built-in control structure of Prolog in order for the program to execute as desired. The example is illustrative only, and the concepts involved will be explained in later chapters. A Prolog logicbase exists in the listener’s workspace as a collection of small modular units, called predicates. Next add the report-writing code, again being careful with punctuation and upper- and lowercase.

Through exercises you will also build a simple expert system, an intelligent genealogical logicbase, and a mundane customer order entry application.

Here are some examples of their use. Go back to the edit window and add the line person plato. When you understand terms such as predicateclausebacktrackingand unification you will have a good grasp of Prolog. They are similar to subroutines in conventional languages, but on a smaller scale.
