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

Action Reasoning:
To get closer to the goal state, we need to move car_2 from curb_1 to curb_3 where car_3 is currently parked, freeing up curb_1. Then, car_1 can move from curb_2 to curb_1, achieving its goal position.

New State Description:
Curb_0 contains car_0, clear. Curb_1 is empty and clear. Curb_2 contains car_1, clear. Curb_3 contains car_3 and car_2 parked behind it; car_3 is not clear, car_2 is clear. Car_0 is parked and clear. Car_1 is parked and clear. Car_2 is double-parked and clear. Car_3 is parked and not clear.

Action Chosen:
(move-curb-to-car car_2 curb_1 car_3)
