Attempt Number: 4
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 configuration while having each car clear, we can use Curb 1 as a temporary position. First, move car_2 to Curb 2 (already containing car_3) temporarily, enabling car_1 to be swapped into Curb 1, matching its goal position.

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

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