The Garden: Evolving Warriors in Core Wars

The Garden is a new architecture for evolving Core Wars programs, short, assembly-language like creatures which battle in a simulated computer environment.

The resulting eÆciency allows us to explore and compare di erent evolutionary methods at a scale (thousands of war...
