Knowledge-Based Agent

A knowledge-based agent stores sentences in a knowledge base (KB) and infers new ones before acting. Tell the KB facts. Ask it queries. Inference engine applies rules. Contrast with a simple reflex: no KB, just if-then on the current percept.

Wumpus world is the textbook playground: breeze → maybe pit nearby. Don’t dump Prolog unless they ask. Say KB + inference + action.

Output — idea / do / check for Knowledge-Based Agent. Fill those three in the viva.

Exam tip

KB vs simple reflex in one contrast.

Example

# Knowledge-Based Agent
print("idea :", "Knowledge-Based Agent")
print("do   : one tiny example on paper")
print("check: one failure case")

Output: idea / do / check for Knowledge-Based Agent. Fill those three in the viva.

Short notes

DefKB + inference + action.
RuleTell / Ask.
