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).
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
Gene Pool is an artificial life simulation where populations of physics-based organisms evolve over time.
An imaginary gene pool, a primordial puddle of genetic surprises. Free download; Windows.
Freeware artificial life program designed for Windows. 2-dimensional evolutionary world with simulated neurons.
Java application simulates creature behaviours and movement. Available for free download, including source code, and a paper on Artificial Life.
Agents evolve to stay on the screen.
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?
Predators is an open-ended play-by-e-mail game. The game is an abstract simulation of animal species evolution.
