Discuss the theoretical arguments and the architecture of Deen$$s reactive agents $($also known as Cooperating Knowledge Based Systems$).[$ feel free to use some of this information$-$ Deen$$s reactive approach $($Deen$,$ et al$.,1990-)$ is

known as an engineering approach to multiagent systems or Cooperating KnowledgeBased Systems $($CKBS$)$

$$ mentalistic primitives are unpredictable and hence

computational behaviour cannot be guaranteed

$$ agents should be endowed with computational rather

than mentalist properties $$ and emphasis is on

completeness, correctness, predictability and

termination in distributed problem$-$solving

$$ each agent is a high$-$grain autonomous entity, with a

compulsory software component and an optional

hardware component.

Deen$$s Reactive Agents

$$ Deen$$s agent design is driven by three main behavioural

characteristics: autonomy, cooperation and the ability to have multiple

skills with a view to achieving flexibility, adaptability, fault tolerance

and robustness

$$ The agent has two major parts $($or models$)$:

$$ An external model $($head$),$ which maintains all the information

needed for rational decision$-$making and communication with other

agents. It also includes the agent$$s controller which is responsible

for maintaining the agent$$s autonomy and execution control.

$$ An internal model $($body$)$ that encapsulates a number of

components needed for mechanisation of the agent$$s skills. It can

contain an optional hardware or human component, although the

human component is not considered any further in the

computational model because of its complexity.

Deen$$s agent model

$25$

$$ Deen$$s model has a compulsory

head and optional body:

$$ a head for decision making and social

interaction, and

$$ a body for mechanisation of its

decisions$/$skills$.$ The body may also

include electromechanical parts.

$$ the neck of the agent provides a

physical communication link such as a

network connection between the body

and the head, and supports the

mappings $($data and control

messages$)$ involved between the body

and the head.
