Consider the following gridworld MDP. The states are grid squares, identified by their row and column number (row first). The agent always starts in state (1,1), marked with the letter S. There are two terminal goal states, (2,3) with reward 5 and (1,3) with reward -5. Rewards are 0 in non-terminal states. (The reward for a state is received as the agent moves into the state). The transition function is such that the intended agent movement (Up, Down, Left, or Right) happens with probability .8. With probability .1 each, the agent ends up in one of the states perpendicular to the intended direction. If a collision with a wall happens, the agent stays in the same state. +5
S -5
Which of the following is the optimal policy for this grid ?
A. Right Right +5
Up Left -5
B. Down Left +5
Right Up -5
C. Right Down +5
Up Right -5
D. Right Right +5
Right Right -5
