This is a list of on-line Alife papers. This includes ones on genetic programming, learning, autonomous agents, robotics, and evolution.

The sources are divided into three categories: individual authors, institutions, and miscellaneous. Items that go in the institutions category are archives for an entire site or group (SFI, for example).

Meta pages and software are listed under Miscellaneous.

Institutions

• Santa Fe Institute publications, including their tech reports and pointers to ALife WWW resources
• Reed College ALife group
• University of Sussex COGS group tech reports on evolutionary and adaptive systems.
• UCSD: William E. Hart's on-line publications. William Hart was a grad student of Rik Belew's. There's also an on-line bibliography of publications from Rik Belew's Cognitive Computer Science Research Group at UCSD, and some of the entries have links to on-line copies.

Miscellaneous

• Software from SFI's ALife On-Line. A good place to start if you're looking for a system. Includes StarLogo, Tierra, Polyworld, and Echo.
• ALife Mac software, various authors. MacTierra, Life, and others.
• NetQ, Stewart Wilson's on-line manuscript service. This is a great idea -- authors can put their manuscripts here and receive section by section feedback from readers. After reading a section, you are given the chance to submit new comments and read previously posted ones (along with the author's responses).
• Genetic Programming archive at UTexas. Papers and software.
• EvoX documentation. Software by Vince Darley.
• POPBUGS description. POPBUGS is a package that lets you simulate robots in a 2-D world.
