On-line resources appear, disappear, and move with great speed, so all the addresses here (and elsewhere in the book), which were correct at the time of writing, are obviously subject to change without notice after publication. Hopefully, the most valuable resources should be readily findable using standard search tools.
One of the key on-line resources is the GP bibliography (Langdon et al., 1995-2008). 3 At the time of writing, this bibliography contains about 5,000 GP entries, roughly half of which can be downloaded immediately.4
The GP bibliography has a variety of interfaces, including a graphical representation of GP's collaborative network (see Figure A.1 ). The bibliography allows for quick jumps between papers linked by authors and allows one to sort the author list by the number of GP publications. Full references are provided in both BIBTEX and Refer formats for direct inclusion in papers written in LATEX and Microsoft Word, respectively. The GP bibliography is also part of the Collection of Computer Sciences Bibliographies (Achilles and Ortyl, 1995-2008), which provides a comprehensive Lucerne syntax search engine.
From early on there has been an active, open email discussion list: the Genetic Programming mailing list (2001-2008). The EC-Digest (1985-2008) is a moderated list covering evolutionary computation more broadly, and often contains GP related announcements.
Koza's http://www.genetic-programming.org/ contains a ton of useful information for the novice, including a short tutorial on "What is Genetic Programming" and the Lisp implementation of GP from Genetic Programming (Koza, 1992).
