Herself’s Artificial Intelligence

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.

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.
