Attempt Number: 4
Error Message: Action not unique compared to other actions chosen from this state before. Choose a new action

Action Reasoning:
To move closer to our goal, we should free up Curb_3 by moving Car_3 elsewhere since it is currently double-parked. Moving Car_3 to the empty Curb_0 using move-car-to-curb will clear the way for Car_0 to be moved directly to the position it occupies. Once Car_0 is clear on Curb_3, it can be exchanged with the destination Curb.

New State Description:
- Curb_0 now contains Car_3 and is no longer empty. Car_3 is clear.- Curb_1 still has Car_1 on it and is clear.- Curb_2 still has Car_2 on it and is clear.- Curb_3: Car_0 is parked on it, Car_0 is now clear.

Action Chosen:
(move-car-to-curb car3 car0 curb_0)
