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

Action Reasoning:
To achieve the goal state, car_2 must be parked on curb_2. Moving car_2 from behind car_1 to the empty curb_1 using move-car-to-curb will free up space. This makes curb_3 organized for car_1 and also preps car_2 for a straight swap with car_3 next.

New State Description:
Curb_0 contains car_0, clear. Curb_1 now contains car_2, clear. Curb_2 contains car_3, clear. Curb_3 contains car_1, clear after car_2 left. Car_0 is parked and clear. Car_1 is parked and clear. Car_2 is parked and clear in curb_1. Car_3 is parked and clear.

Action Chosen:
(move-car-to-curb car_2 car_1 curb_1)
