Types of Agents

Types in order of power: simple reflex (if dirt then suck). Model-based reflex (keeps an internal map). Goal-based (plans toward a goal). Utility-based (picks the better of two good goals). Learning agent (improves from feedback).

Thermostat is simple reflex. A robot vacuum that remembers cleaned tiles is model-based. A GPS that compares routes is utility-ish. Say the ladder; don’t memorise only names.

Output — idea / do / check for Types of Agents. Fill those three in the viva.

Exam tip

Name four types + one example each.

Example

# Types of Agents
print("idea :", "Types of Agents")
print("do   : one tiny example on paper")
print("check: one failure case")

Output: idea / do / check for Types of Agents. Fill those three in the viva.
