Consider the familiar robot navigation task within the gridworld shown above. You can move in any of the four directions (left/right/up/down) unless blocked by one of the gray obstacles at B2 and B3. The rewards are +10 for state C4, and -10 for state B4. A4 and B4 are both absorbing states. The reward for every other state is 0.
