coop_wumpus

Our new approach aims to allow multiple agent approaches to work together on a wumpus environment. An executable file in java - which can be fed with the locations of the files for two agents - will simulate one walkthrough in our partially observable, strategic, sequential, static, discrete multiagent wumpus world. wumpus world with gym env

Actions

Perception of the Player

Perception of a player is limited to the cell she is standing on (partially-observable) This means the state of only this one cell is fixed but she is meant to remember the states of cells she has been to since they dont change a lot.

actions of the player

• walk_up
  • the player can walk one cell every move
• walk_down
  • the player can walk one cell every move
• walk_left
  • the player can walk one cell every move
• walk_right
  • the player can walk one cell every move
• pick up
  • the player can pick up gold if she is on a gold cell
• put down
  • if the player has gold she can put it back on the ground
• climb
  • the wumpus cave has to be left climbing out the way the player entered
• scream
  • a scream can be heard by other players and will be represented as a vector
• nothing
  • do nothing for one turn

goal

pick up a piece of gold and leave (asap?)
