Prolog is equally adept at supporting top-down or inside-out program development.

As we introduce the vocabulary of Prolog, synonyms from Prolog or other computer science areas for a term will follow in parentheses. Your persona as the adventurer is that of a three year old girl.

If you forget the period and you probably willyou can enter it on the next line with a ‘return. You have had your first glimpse of Prolog and should understand that it is fundamentally different from most languages, but can be used to accomplish the same goals and more. In all the listener examples in this book, you enter the text after the prompt? Eclipse IDE, first create a project for your source files.

The Nani is your security blanket. Through exercises you will also build a simple expert system, an intelligent genealogical logicbase, and a mundane customer order entry application. Each chapter will call for the addition of more and more predicates to the game.

A clause can be either a fact or a rule. This book is designed to be used with a Prolog listener, azmi will guide you through the building of four applications.

This predicate is called when “nanisrch” starts up.

While Prolog is a fascinating language from a purely theoretical viewpoint, this book will stress Prolog as a practical tool for application development. Now let’s change the program. It was developed from a foundation of logical theorem proving and originally used for research in natural language processing.

It should write a message indicating whether prollg not it’s time to reorder. In addition to ‘is,’ Prolog provides a number of operators that compare two numbers. However, arithmetic does not fit nicely into the logical scheme of things. The lost treasure with magical powers is your nani security blanket. One is code, meant to be entered in a source file, and the other is interactions with the listener.

A Prolog logicbase exists in the listener’s workspace as a collection of small modular units, called predicates. We ammzi finish with the natural language interface.

Your mission is to find the Nani.

Similarly, we can assert the simple fact that Socrates is a person. Go back to the edit window and add the line person plato. Logic Programming Let’s look at the simple example in more detail.

Similarly, the exercises will ask you to add predicates to each tuotrial the other applications. For example, at the highest level we have a Prolog program logicbase.

Sample program 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. These are the adventure game Nani Searchthe intelligent genealogical logicbase Familythe customer order entry system Custordand the expert system Birds.

Once you’ve loaded the program, try the following Prolog queries. The listener responds yes We could also ask “Who is mortal? A programmer needs to do things that have nothing to do with logic, such as read and write terms. The Prolog program is composed of predicates procedures, record types, relations.

Its syntax calls for the use of operators, which will be described in more detail in chapter tuforial You are in the kitchen. Each of these three predicates has a distinctly different flavor. This message is followed by the typical listener prompt. The example is illustrative only, and the concepts involved will be explained in later chapters.

Here are two example predicates.

When working with Prolog, it is important to remember to include the final period and to press the ‘return’ key. The adventure tutoial is a good example since it contains mundane programming constructs, symbolic reasoning, natural language, data, and logic. Puzzle is only called from goto for this reason.
