I’ll add to this list as I run across new sites.

Electric Sheep is a collaborative abstract artwork founded by Scott Draves. It’s run by thousands of people all over the world, and can be installed on any ordinary PC or Mac. When these computers “sleep”, the Electric Sheep comes on and the computers communicate with each other by the internet to share the work of creating morphing abstract animations known as “sheep”. The result is a collective “android dream”, an homage to Philip K. Dick’s novel Do Androids Dream of Electric Sheep.

Anyone watching one of these computers may vote for their favorite animations using the keyboard. The more popular sheep live longer and reproduce according to a genetic algorithm with mutation and cross-over. Hence the flock evolves to please its global audience. You can also design your own sheep and submit them to the gene pool.

I ‘ve been re-reading ‘Out of Control, The Biology of Machines’ and took some time to look up some of the people mentioned who are creating virtual plant life.

If you are interested in creating plants for artificial worlds, or to use to study botany you’ll want to start with the Algorithmic Botany website. There are tons of papers you can download, a book ‘The Algorithmic Beauty of Plants’ and every thing you need to know about ‘cpfg’ the Plant and Fractal generator with Continuous Parameters. Which is a program you can use to generate your own plants using the L-system ( Lindenmayer System ).

If you’d like to dig into the L grammar itself as well as generate plants check out GroIMP, open source Java 3D software for modeling growth grammars.

JBotSim is a simulation library for prototyping distributed algorithms in dynamic networks. The style of programming in JBotSim is event-driven: your algorithms are defined as subroutines to be executed when some particular events occur (e.g. ring of an alarm clock, appearance/disappearance of a link, arrival of a message, movement of the underlying node, etc.). Movements of the nodes can be either controlled by the algorithm itself (e.g. mobile robots), by an independent algorithm (e.g. mobility model), or by means of mouse-based interactions during the execution. Besides its features, the main asset of JBotSim is its simplicity of use. ( read more The JBotSim Library )

Examples

Pyevolve was developed to be a complete genetic algorithm framework written in pure python, the main objectives of Pyevolve is:

* written in pure python, to maximize the cross-platform issue;
* easy to use API, the API must be easy for end-user;
* see the evolution, the user can and must see and interact with the evolution statistics, graphs and etc;
* extensible, the API must be extensible, the user can create new representations, genetic operators like crossover, mutation and etc;
* fast, the design must be optimized for performance;
* common features, the framework must implement the most common features: selectors like roulette wheel, tournament, ranking, uniform. Scaling schemes like linear scaling, etc;
* default parameters, we must have default operators, settings, etc in all options;
* open-source, the source is for everyone, not for only one.
