Explain the PEAS description for the Wumpus task environment in the Wumpus World scenario.
Performance measure: +1000 for picking up gold, -1000 for falling into a pit or being eaten, -1 for each action taken, -10 for using up the arrow. Environment: 4x4 grid of rooms, with the agent starting at [1,1] and gold and Wumpus placed randomly. Each square (except the start) can be a pit with 0.2 probability. Actuators: Agent movements are forward, turn left or right by 90 degrees. The agent can use Grab to pick up an object in the same square, and Shoot to fire an arrow in a straight line. The agent has only one arrow. Sensors: 5 sensors provide information about the presence of stench in the square containing the Wumpus and in directly adjacent squares, as well as the perception of a breeze in squares directly adjacent to a pit.

What are the potential consequences for the agent in the Wumpus World environment?
The potential consequences for the agent include receiving +1000 for picking up gold, -1000 for falling into a pit or being eaten, -1 for each action taken, and -10 for using up the arrow.

Study Notes
PEAS Description for the Wumpus Task Environment
- Performance Measure: Success is measured by finding the gold, exiting the cave alive, and avoiding the Wumpus and pits; penalties apply for actions like falling into pits or being killed.
- Environment: The Wumpus World consists of a grid of rooms where agents navigate, face hazards (Wumpus, pits), and find treasures (gold) while adhering to various constraints.
- Actuators: The agent can move through rooms, shoot arrows to kill the Wumpus, and pick up gold; movement is restricted to adjacent rooms.
- Sensors: The agent receives sensory inputs indicating the presence of danger (stench from Wumpus, breeze from pits, glitter from gold), helping navigate the environment.
Potential Consequences for the Agent
- Falling into Pits: Results in the instant demise of the agent if it moves into a pit.
- Being Killed by Wumpus: Moving into a room with the Wumpus leads to the agent's death.
- Loss of Gold: Failing to retrieve gold means lost potential rewards.
- Limited Resources: The agent has a finite number of arrows; once spent, it cannot kill the Wumpus anymore.
Actuator Capabilities
- Moving: The agent can move left, right, up, or down between adjacent rooms in the grid.
- Shooting: The agent can fire an arrow to potentially eliminate the Wumpus if positioned correctly.
- Grabbing: The ability to pick up gold once entered the corresponding room.
Perception of the Environment
- Sensor Inputs: The agent detects stench (indicating nearby Wumpus), breeze (indicating adjacent pits), and glitter (indicating gold presence).
- Grid Snapshot: The environment can be perceived as a series of rooms with specific attributes that affect decision-making.
Layout of the Wumpus World Environment
- Grid Structure: Typically a 4x4 grid, but can vary; rooms contain hazards, treasures, or are empty.
- Room Features: The presence of the Wumpus, pits, and gold is arranged randomly, impacting the agent's strategy.
- Walls: The grid boundaries restrict movement, limiting access to adjacent rooms.
