AIMA Python Code

This file gives an overview of the Python code for the algorithms in the textbook AI: A Modern Approach. The code is Copyright (c) 2002 by Peter Norvig and is offered free of charge for your use. As you may know, the textbook presents algorithms in pseudo-code format; as a supplement we provide this Python code as well as Lisp code. The intent is to implement all the algorithms in both languages, so that you can choose whichever language you prefer. As yet neither implementation is complete, but the Lisp version is closer.

Installation Instructions

Here is how to download the files and make them ready for use. You only need to do this once, and if you are taking a course, your instructor may have set this up for you.

1. Create a directory where you want the code to reside on your local machine. You can call this whatever you want; we'll call it home.
2. Get the data.zip, store it in home file and unzip it. Your browser may unzip automatically, or you can give the command "unzip aima-python.zip" or drag the file to your zip program icon. In the end, just make sure you have files in the directory home/data.
3. Download the file aima-python.zip into home.
4. Unzip it, creating files in home/python.
5. You must have Python (version 2.2 or later) installed. Python comes preinstalled on most versions of Linux and Mac OS. Versions are also available for Windows, Solaris, and other operating systems. If your system does not have Python installed, you can download and install it.
6. Make sure that home/python is in your module search path. You do this either by always starting Python from the directory where you keep the files, or by editing the environment variable PYTHONPATH.
7. Test the code. There are unit tests interspersed in the code. They follow the Python doctest conventions and can be run with the command line "python doctests.py -v *.py". The "-v" is optional; it means "verbose". Various output is printed, but if all goes well there should be no instances of the word "Failure", nor of a long line of "*****". If you do use the "-v" option, the last line printed should be "Test passed."

User's Guide

Once you have the files installed, you can use them in several ways.
• Read the code. This can enhance your understanding of the algorithms, and clarify parts that were not spelled out in the book's pseudo-code.
• Run the existing code on your own data. For the module(s) you want, do "import module" and then run the functions you want on the data you want.
• Experiment with extending the code.

Code File Summary

You can
• Browse through the python/ directory to see all the files.
• Look at the .txt files to see some unit tests (doctests) and their expected output.
• See the code repository index to see what functions and data types are available, and how they map to the pseudocode figures in the book.
The following table lists the code files (modules), the chapters in the book to which they refer, the number of lines of code in each file, and a brief description of each file. Each module name links to a pretty, colorized version of the Python source code, and the Files column lists the original .py file and (in some cases) a .txt file of doctests.
