Inert and inhabited dynamical systems
Erik J. Sandewall · 1995
Abstract This book addresses the knowledge repreSCDtation and reasoning about inert and inhabited dynamical systems, where the agent(s) inhabiting the system are characterized by their ability to perform actions. A system is then defined in a quite general fashion as a collection of objects which have individual properties as well as relationships between each other. Color, weight, and velocity are examples of properties; adjacency, support, and mutual visibility are examples of relationships. The property assignments and relationships that hold in the system at a point in time constitute its state. A part of the state may be designated as the system’s input at the preSCDt time.
