John Holland's ECHO - Echo is a simulation tool developed to investigate mechanisms which regulate diversity and information-processing in systems comprised of many interacting adaptive agents, or complex adaptive systems (CAS).Framsticks - evolution simulation - a three-dimensional life simulation project
Hardware Artificial Life (HAL) - Lotus Artificial Life's Java cellular automata substrate capable of supporting evolving, self-reproducing organisms which are capable of universal computation.
The Swarm Simulation System - The Swarm Simulation System
Gene Pool for Windows. - Gene Pool is an artificial life simulation where populations of physics-based organisms evolve over time.
Darwin Pond (windows) - Darwin Pond is an imaginary gene pool, a primordial puddle of genetic surprises.
Gene Lab - Gene Lab is an artificial life simulation of plant/animal population dynamics. It uses genetic algorithms to produce optimal behavior for the plant-eating animals.
ALife Garden - Watch and participate in some artificial lives.
e-den... artificial life in cyberspace - e-den is a freeware artificial life program designed for the Windows environment.
Java, Artificial Life, and creature behaviour - Java application simulates creature behaviours and movement. Available for free download, including source code, and a paper on Artificial Life.
Individual-Based Fish Modeling At Humboldt State University - Modeling software, theory, and applications. Instream flow model for trout. Salmon out-migration survival simulator.
Quantum Life Forms - Emergence of twin life forms from the simplistic, decentralized actions of thousands of component elements
Critters - Agents evolve to stay on the screen.
PolyWorld Information (author's site) - Source of information, technical report, and source code for the PolyWorld computational ecology, maintained by Larry Yaeger, PolyWorld's author. (This site contains more up to date links and information than the PolyWorld page at the Santa Fe Institute site.)
Biotopia - Biotopia is a Darwinian evolution program. Lots of parameters to set, lots of emergent behavior to get.
Evolving Artificial Moral Ecologies - The project seeks to extend current work in the evolution of cooperation by the considered inclusion of spatial elements and resource dependency into the models. It also deliberately seeks to integrate agent-based and population approaches to modeling evolutionary processes.
JuhasWorld - JuhasWorld: Yes it's alive! You have to see this applet to believe it. Just let those actors evolve for a few generations and they suddenly seem quite clever indeed. Wait a few more generations and you will be completely hooked: How good can they get?
Mirek's Cellebration, 1D and 2D Cellular Automata viewer, editor and explorer - A collection of information relating to cellular automata.
Virtual World of Decision Making Turtles - a simulation of "turtles" that move, eat and evolve using a genetic algorithm. Includes online demos, downloads and descriptions.
Predators - Predators is an open-ended play-by-e-mail game. The game is an abstract simulation of animal species evolution.
The Virtual FishTank - Designed for people of all ages, the FishTank offers firsthand experiences in creating artificial life forms and reveals how simple behavioral rules can produce complex and surprising results.
NecroBones Artificial Life Experiments - Features three Java artificial life experiments.
Keith's Artificial Life - An extensive collection of macintosh alife programs fitting into genetic algorithms, large swarms, evolutionary simulations, complex neural networks, and other related subjects.
The MatremPage - An experiment in artificial life, and a game as well, where players create new animals to struggle and survive.
Sugarscape - The simulation of social phenomena at Brookings Institute
Eden - A networked, self-generating artificial ecosystem by John McCormack
Genesis - A project being developed by David Stern at Cambridge university. Available in stand alone or '@home' flavours.
Sharks and Fish with sexual selection - An evolutionary computation project by Sigrid Hammarquist and Svetla Chakarova.
CoreLife - Implements an artificial-life environment based on - and compatible with - Tierra, Tom Ray's well-known project, which displays open-ended evolution using a world of assembly-language creatures running on simulated parallel processors.
Red Bird Island: Artificial Life - Simple world with automata that act to form complex systems. Implimented on the Macintosh.
