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

Action Reasoning:
To align car_2 with its desired position on curb_2, I will move car_3 from behind car_2 to the empty curb_0, which frees car_2, moving us closer to the goal state.

New State Description:
Curb_0 now has car_3 parked and clear. Curb_1 has car_2, which is now clear. Curb_2 remains with car_0 parked and clear. Curb_3 continues to have car_1 parked and clear. Car_3 has vacated car_2 and is clear.

Action Chosen:
(move-car-to-curb car_3 car_2 curb_0)
