What is the difference between a knowledge-based agent and a rational agent? Is a knowledge-based agent also rational?


What is the difference between a knowledge-based agent and a rational agent? Is a knowledge-based agent also rational?

en.wikipedia.org/wiki/Rational_agent

a rational agent is an agent that has clear preferences, models uncertainty via expected values, and always chooses to perform the action with the optimal expected outcome for itself from among all feasible actions.

Apparently, a knowledge-based agent includes a knowledge base and an inference system.

en.wikipedia.org/wiki/Inference_engine

The inference engine applied logical rules to the knowledge base and deduced new knowledge.

IMHO, this would make a knowledge-based agent also rational….  ;^)
