The SOS Algorithm
SOS is an algorithm which automatically designs finite state machines (FSM) capable of solving a given task. The interpretability of FSM makes SOS particularly suitable for problems involving the design of controllers. SOS uses a variation of reinforcement learning applied to FSM and an island-based genetic algorithm.
