Perceive-Reason-Act Cycle

The '''perceive-reason-act cycle''' in cognitive
[[Agent|agents]] is the connection between the [[Agent|agent]] 
and the environment. This cognitive feedback
loop consists of a perception phase, where the state of the
managed element is observed, monitored and analyzed, and
and a corresponding action phase, where the managed element
is controlled through corrective action which is planned and 
executed. 

It can vary in the level of detail 
and occurs in several [[X_Computing|x-computing]] initiatives.
The concept of an autonomic manager used in
[[Organic Computing]] and [[Autonomic Computing]]
in order to achieve [[Self-Star Properties|self-* properties]].
is usually based on such a [[Feedback|feedback]] loop.
