Question
4. You have the agent program for simple reflex agent as shown below
function
if status = Dirty then return Suck
else if location = A then return Right
else if location = B then return Left
REFLEX-VACUUM-AGENT([location, status]) returns an action
Figure 2.8 The agent program for a simple reflex agent in the two-state vacuum environ-
ment. This program implements the agent function tabulated in Figure 2.3.
Now suppose you can use one more action "NoOp" which does nothing.
a. Would it be desirable to use this action in this agent program to prevent vacuum cleaner
from moving after all squares are cleaned? If yes, modify the simple reflex agent program
adding "NoOp" action and if not give an argument that despite the option of "NoOp" the
agent is bound to keep moving. [4]
b. If you have a choice of using other type of agents, which one would you choose and how
would it prevent vacuum from moving after all squares are cleaned? [3]
Use the assumptions listed below
• The performance measure awards one point for each clean square at each time step, over a
"lifetime" of 1000 time steps.
• The "geography" of the environment is known a priori (Figure 2.2) but the dirt distribution and
the initial location of the agent are not. Clean squares stay clean and sucking cleans the current
square. The Left and right actions move the agent left and right except when this would take
the agent outside the environment, in which case the agent remains where it is.
• The only available actions are Left, Right, Suck and NoOp
The agent correctly perceives its location and whether that location contains dirt
