Attempt Number: 2
Error Message: Action not unique compared to other actions chosen from this state before. Choose a new action

Action Reasoning:
To advance towards the goal state, we need to move car3 from behind car2 to occupy an empty curb. Curb_3 is currently clear, so moving car3 there will align it with the goal state for curb_3.

New State Description:
- Curb_0: Empty and clear.- Curb_1: Car_1 is parked on it with car0 double parked behind it. Car_1 is not clear, car0 is clear.- Curb_2: Car_2 is parked on it and is now clear since car3 has moved. Car_2 is clear.- Curb_3: Car_3 is parked on it and is clear.

Action Chosen:
(move-car-to-curb car3 car2 curb_3)
