An ideal rational agent is the one, which is capable of doing expected actions to maximize its performance measure, on the basis of −
● Its percept sequence
● Its built-in knowledge base
Rationality of an agent depends on the following four factors −
● The performance measures, which determine the degree of success.
● Agent’s Percept Sequence till now.
● The agent’s prior knowledge about the environment.
● The actions that the agent can carry out.
A rational agent always performs right action, where the right action means the action that causes the agent to be most successful in the given percept sequence. The problem the agent solves is characterized by Performance Measure, Environment, Actuators, and Sensors (PEAS).
