Exercise $2.$

Start with a simple reflex agent

a$)$ Design a rational vacuum agent for the following situation:

$1.$ The environment consists of a set of $4$ rooms placed in a square. See the picture below.

$2.$ The agent is sensor less.

$3.$ The agent can:

$$ move right, left, up or down

$$ suck dirt $($SD$)$ from a room

$$ stay idle $($SI$)$

$4.$ The rooms are either dirty or clean. A clean room stays clean. A dirty room becomes clean if SD

is performed by the agent in that room.

$5.$ The performance measure of the agent sums up over a period of time the number of clean rooms

at each time slot.

b$)$ Explain why the agent is rational.

c$)$ Then make it a rational model$-$based agent

d$)$ Explain why the new agent is rational.
