Thus for a medical diagnostic agent, if a certain set of symptoms is present, given a certain medical history, offer X diagnosis.

Some expert systems fall under the category of reflex agent. Reflex agents are really not very bright.

Introduction to Intelligent Agents

They just cannot deal with novelty. If SARS is not in the database of pathogens, and the patient has symptoms associated with SARS, the reflex agent will not seek to update its records by consulting other agents.


It will not accumulate experience that may indicate a new disease is present. It will not proactively check on patients to see if there may be some better diagnosis.

It will not learn from its experience. If the percept is not in the reflex agent's database, the agent cannot react appropriately to the situation.

One might argue that the simple mercury type thermostat also is a reflex agent with only three rules. If the temperature reaches x, then turn the the design of intelligent agents on.

If the temperature reaches y, then turn the heater off. The main difference is that the reflex agent requires a program that is not itself immediately and mechanically linked to the environment. Goal based agent An intelligent agent contains features of its less complex relatives, but it is not so limited.

It acts in accordance with an agenda. It has a goal or set of goals that it actively pursues. A goal-based agent has a representation of the current state of the environment and how that environment generally works. It pursues basic policies or goals that may not be immediately attainable.

G54DIA Designing Intelligent Agents

These agents consider different scenarios before acting on their environments, to see which action will probably attain a goal. This consideration of different scenarios is called search and planning.


It makes the agent proactive, not just reactive. Another interesting feature of the goal-based agent is that it already has some model of how the objects in its environment usually behave, so it can perform searches and identify plans based on this knowledge about the world.

Among the actions that can occur the design of intelligent agents the world are the agent's own actions. So the agent's own possible actions are among the factors that will determine possible future scenarios.

In a report on technology used in this mission, the software designers described the domain and concept as follows: Maintenance of internal spacecraft functioning, including automated vehicle health the design of intelligent agents.

Intelligent agent - Wikipedia

The design of intelligent agents vehicle health management uses sensor data plus a stored model of spacecraft components and functions to reason about current state and to plan for recovery from system faults.

If Remote Agent were a mere reflex agent, it would have to have a look up table for every possible scenario, which would take up too many computational resources and probably tax any engineer's imagination.

As the agent developers of Remote Space pointed out in the design of intelligent agents report: Software systems for vehicle monitoring, diagnosis, and control can be very complex, difficult to develop, difficult to debug and validate, and difficult or dangerous to modify during a mission.

The software must allow for multiple simultaneous component failures -- possibly including sensor noise or failures -- and provide rapid response even to situations unforeseen [sic] by design engineers.
