This is the repository for the book Paradigms of Artificial Intelligence Programming: Case Studies in Common Lisp by Peter Norvig (1992). Here you'll find:
- A directory of all the Lisp code from the book.
- A
pdfof the book, split into two parts (because GitHub can't handle big files) covering Chapters 1-14 (PAIP-part1.pdf) and 15-25 (PAIP-part2.pdf). The copyright has recently reverted to me, and I choose to share it under MIT license. - A rough
txtexport, from the pdf, PAIP.txt, containing many errors. - We're in the process of making a nice online version of the book; here's the first draft of a few sample chapters.
As seen on TV. See also: errata, comments, preface, retrospective.
There is no single "application" to run. Rather, there is a collection of source code files, duplicating the code in the book. You can read and/or run whatever you like. Lisp is an interactive language, and you will need to interact with the code to get benefit from it. Some hints:
- You will need a Common Lisp interpreter/compiler/environment. Here's a discussion of the options.
- You will always need
(load "auxfns.lisp"). - You will need
(requires "file"), for the various instances of file that you want to use. (Ifrequiresdoes not work properly on your system you may have to alter its definition, inauxfns.lisp. - The function
do-examples, which takes as an argument either:allor 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. Access this by doing(requires "examples").
The index below gives the chapter in the book, file name, and short description for each file.
