Maezumo - The Corewar Evolver with a Twist
Maezumo is an open-source program that automatically generates "warbot" programs (known as warriors) for the game Corewar.
In Corewar these warriors battle each other in the core memory space of a virtual computer called MARS (Memory Array Redcode Simulator) to eliminate all opponents.
To get an idea how Maezumo works check out the working principle.
