Paradigms of AI Programming Source Code

This page is the index for the Lisp source code files for the book Paradigms of Artificial Intelligence Programming. The code is offered as open source freeware under this license. You can browse all the files in this directory.

Installation Instructions

  1. Download the file paip.zip and unzip it.
  2. You must have a lisp compiler/interpreter.
  3. To test all the code, start lisp and do the following at the interactive prompt:
    (load "auxfns.lisp")
    (requires "examples")
    (do-examples :all)
    
    This should print out a long list of inputs and outputs, and the last output should be the total number of errors. If all goes well, this should be "0".

Use

To use the code, edit any of the files or add new files. You will always have to do (load "auxfns.lisp") first, and you will typically have to do (requires "file"), for various instances of file that you want to use.

The function "requires" is used for a primitive form of control over what files require other files to be loaded first. If "requires" does not work properly on your system you may have to alter its definition, in the file "auxfns.lisp". For more complicated use of these files, you should follow the guidelines for organizing files explained in Chapter 24.

The function do-examples, which takes as an argument either :all or a chapter number or a list of chapter numbers, can be used to see examples of the use of various functions. For example, (do-examples 1) shows the examples from chapter 1.
