This page describes the Wumpus-World in detail.
Here you will find all about the possible Percepts and
A for a general description of the Simulator and it's purpose see
Wheter the move was successful or not is displayed with a frame arround this icon. If the frame-color is green the agent made a successful move. In case of the contrary the frame's color is red.
Movement in the four wind-directions:
"UP"
"DOWN"
"LEFT"
"RIGHT"
These moves are only possible if no Wall is blocking the way. In case of such a blocked move a "BUMP"-Percept (=> see below) will be generated, but the agent will not move.
Shooting a javelin/arrow in one of the four wind-directions:
"SHOOT_UP"
"SHOOT_DOWN"
"SHOOT_LEFT"
"SHOOT_RIGHT"
These actions will result in a thrown javelin or arrow that hits the first wumpus that is in the line of sight in the given wind-direction. If there is no wumpus the javelin will break up into pieces when it hits the next wall. (=>it's lost)
Getting the gold:
"GRAB"
Leaving the cave through:
"CLIMB"
This move is only sucessful in the
starting/exit field (the one marked by the green
exit-sign
). Wheter the "CLIMB" was or was not
sucessful the agent will only know by that fact that it
is still in the Wumpus-World or not.
"GOLD"-Percept:
(cumulative)
There is at least one piece of gold in the current
field...
"STENCH"-Percept:
(cumulative)
There is a wumpus near the current field (up,
down, left or right).
"BREEZE"-Percept:
(cumulative)
There is a pit near the current field (up, down,
left or right).
"BUMP"-Percept:
(cumulative)
The agent ran into a wall with it's last move.
"SCREAM"-Percept:
(cumulative)
Some one - if not the agent himself - killed the Wumpus
with a javelin.
"EMPTY"-Percept:
(none-cumulative)
This Percept is generated in the absence of all the above
Percepts. In this case the agent may move randomly
without risking it's life.
"FALL": (*)
An agent may
take a step into a bottomless pit which will
result in a fatal fall. The agent is always warned that a
pit is near through the "BREEZE"-Percept
but it may decides to ignore this percept and move on.
"GOBBLE":(*)
If the
agent ignores the "STENCH"-Percept it received,
it may decide to move in the Wumpus' field. The pleasure of
meeting this geek will shure be a short one, because the agent
is gobbled by the agent at once (not even a saint agent - like
Jonathans whale voyage - will survive this terrible ordeal).
(*)Remark: only the first, green agent will ever execute these moves, see below)
