The Wumpus world is a simple world example to illustrate the worth of a knowledge-based agent and to represent knowledge representation. It was inspired by a video game Hunt the Wumpus by Gregory Yob in 1973.

The Wumpus world is a cave which has rooms connected with passageways. We have a knowledge-based agent who will go forward in this world. The cave has a room with a beast which is called Wumpus, who eats anyone who enters the room. The Wumpus can be shot by the agent, but the agent has to find an arrow first, which spawns somewhere in the cave. In the Wumpus world, there are pits which are bottomless, and if the agent falls in a pit, he will be stuck there forever. The agent goal is to find the arrow and kill the Wumpus without falling into a pit or getting killed by the Wumpus.
In the rooms directly adjacent to a pit, the agent can perceive a breeze. In the rooms directly adjacent to the wumpus, the agent can perceive a stench.
