Background

In order not to precipitately rush into the theoretical details and functioning of ACS2, we first provide a rather general background of anticipations, genetic algorithms, and learning classifier systems. ACS2 is certainly not a revolutionary new approach but rather a consequence and long awaited necessity in the research areas of anticipations, adaptive behavior, reinforcement learning, and learning classifier systems. The background section provides insights about what led to the consequent development of ACS2 and introduces all ideas relevant to the system.
