a system, in software or in hardware, that receives sensor input from the environment, selects actions, and may receive evaluative feedback reflecting the appropriateness of its actions
a system situated in an environment, and a part of it, that senses its environment and acts on it, over time, in pursuit of its own agenda
a system situated within and a part of an environment that senses that environment and acts on it, over time, in pursuit of its own agenda and so as to effect what it senses in the future
a system that operates in and senses properties of its environment, makes decisions and takes action to affect its environment on behalf of its owner or user
An entity that, by sensing and acting upon its environment, tries to fulfill a set of goals in a complex, dynamic environment. Properties: (1) it can sense the environment through its sensors and act on the environment through its actuators; (2) it has an internal information processing and decision making capability; (3) it can anticipate future states and possibilities, based on internal models (which are often incomplete and/or incorrect); (4) this anticipatory ability often significantly alters the aggregate behavior of the system of which an agent is part. An agent's goals can take on diverse forms: (i) desired local states;(ii) desired end goals;(iii) selective rewards to be maximized; (iv) internal needs (or motivations) that need to be kept within desired bounds. Since a major component of an agent's environment consists of other agents, agents spend a great deal of their time adapting to the adaptation patterns of other agents.
An entity with limited perception of its environment that can process information to calculate an action so as to be goal-seeking on a local scale.
An autonomous agent is a system situated in, and part of, an environment, which senses that environment, and acts on it, over time, in pursuit of its own agenda. This agenda evolves from drives (or programmed goals). The agent acts to change the environment and influences what it senses at a later time.
