SIMPLE REFLEX AGENTS :-

> They choose actions only based on the current percept.

> They are rational only if a correct decision is made only on the basis of current precept.

> Their environment is completely observable.

CONDITION-ACTION RULE -

It is a rule that maps a state (condition) to an action.

WHAT IS IDEAL RATIONAL AGENT ?

An ideal rational 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).

RATIONALITY:-

Rationality is nothing but status of being resonable,sensible, and having good sense of judgment.

Rationality is concerned with expected actions and results depending upon what the agent has perceived. performing actions with the aim of obtaining useful information is an important part of rationality.
