Attempt Number: 2
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, I will move car_3 from double parking behind car_1 at curb_3 to occupy the empty curb_0. This will clear car_1, allowing future moves to correctly place it.

New State Description:
Curb_0 now has car_3 parked and clear. Curb_1 has car_2 parked and clear. Curb_2 has car_0 parked and clear. Curb_3 has car_1 parked and clear. Car_3 is no longer double parked and is clear.

Action Chosen:
(move-car-to-curb car_3 car_1 curb_0)
