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

Action Reasoning:
To bring the current state closer to the goal, we need to move car_1 from its double-parked position behind car_2 to curb_3, which is empty. This allows car_2 to become clear and aligns car_1 with its final destination on curb_1.

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. All cars are parked individually on separate curbs.

Action Chosen:
(move-car-to-curb car_1 car_2 curb_3)
