Wumpus World-Artificial Intelligence-Knowledge Based Agent-Logical Agent-Unit-2-Logical Reasoning

Unit - 2 - Logical Reasoning
Logical Agent - Part-2
Example for Knowledge Based Agent - Wumpus World
The Wumpus World is a cave consisting of rooms (4 X 4) connected by pathways.
The Wumpus hiding somewhere in the cave, and that eats anyone who enters its room.
The Wumpus can be shot by an agent, but the agent has only one arrow.
Some rooms contain bottomless pits that will trap anyone who enters into these rooms.
The only goal in this environment is the possibility of finding a bundle of gold
Environment
Square adjacent to the Wumpus are smelly
Squares adjacent to the pit are breezy
Glitter iff gold is in the same square
Shooting kills Wumpus if you are facing it
Shooting uses up the only arrow
Grabbing picks up the gold if in the same square
Releasing drops the gold in the same square
Performance Measure
Gold +1000, Death - 1000
Step -1, Use arrow -10
Actuators
Left turn, right turn, forward, grab, release, shoot
Sensors
Breeze, glitter, and smell
Characterization of Wumpus World Environment

Nicely explained all the concepts. However, when the agent identified the wumpus in a block. Why did it not use the arrow to kill the wumpus? Is it not logical to kill when you can avoid the wumpus or is it because of the -10 penalty on the wumpus killing. But even if it imparts a -10 penalty then it significantly decreases the probability of being killed which is going to be a -1000 in this case. What should a logical agent do in this situation?

Great thank you so much

Thank you

If pit, wumpus, and gold changes, how would it be static??

[@YourShanOnly]

Yes bcs, it changes the position before game. Not during the game. i.e they cannot move from one box to other while the game is on. But the positions can be changed before game is initiated.
