A model subjective system with functions of decision making and action evaluation

By proposing a simplest subjective system I wish to discuss in this paper how close we are and how far still are to the human subjective control system.[1] The system I propose here has a pair of functions of controlling the action of the body. In Fig. 1 Function A is decision making of the future action of the body, and Function B is the evaluation of the decision by monitoring the resulting action and the effect on the environment. If the action is found not satisfactory by Function B, the optimization principle of Function A is modified.
