Attempt Number: 3
Error Message: Action not unique compared to other actions chosen from this state before. Choose a new action

Action Reasoning:
To move closer to the goal state, the clear car_1 should be repositioned. Since curb_3 is clear, moving car_1 there will free curb_2 for car_3 when car_1 is moved later.

New State Description:
Curb_0 contains car_0, clear. Curb_1 contains car_2, clear. Curb_2 contains car_3, clear. Curb_3 contains car_1, clear. Car_0 is parked and clear. Car_1 is parked and clear. Car_2 is parked and clear. Car_3 is parked and clear.

Action Chosen:
