A Blackboard Model of Control

Ihe control problem--which of its potential actions should an Al system perform at each point in the problem -solving process?-- is fundamental to all cognitive processes. To solve the control problem intelligently, Al systems should achieve (at least) the seven behavioral goals set forth in this paper. The paper proposes a blackboard model of control and shows how it achieves the goals. The pdper contrasts the model with three alternative control models and shows how it continues an evolutionary progression of control architectures.
