Recycling the Cycle of Perception: A Polemic

Proactive An agent achieves goals, implicit or explicit. Its behaviour is teleological, planned and future-oriented. Reactive An agent perceives and reacts to environmental change. Its behaviour is causal and past-determined. Model-based It uses models of the world to guide its perception and behaviour. Learning-oriented It acquires new behaviours and new models. Rational It reasons, solves problems and uses tools. Social It collaborates, cooperates, commits and competes with other agents. Linguistic It communicates and coordinates using language. Situated It is embedded or situated in a world to which it is coupled. It is particular not universal. Constraint-based It satisfies and optimizes multiple external and internal constraints.
