Table 2.
Gridworld geometry. From Top: 2D size of the simulation, agents that leave the simulation box continue to receive negative reward and no odor; number of time stamps in the simulation, beyond which simulations are looped; number of actions per time stamp; speed of the agent; noise level below which odor is not detected; location of the source on the grid. See Table 3 for the values of the grid size and time stamps at which odor snapshots are saved.
