Web8 dec. 2024 · The agent can perform 4 non-deterministic actions: move up, down, left, and right. It has an 80% chance of moving in the chosen direction, and a 20% chance of moving perpendicularly. My process is to loop over the following: For every tile, calculate the value of the best action from that tile WebTo implement policy iteration, first we need functions for both policy evaluation and policy improvement. For policy evaluation, we use a threshold θ as the stop criterion. limited exam code
