Attempt Number: 6
Error Message: Action not unique compared to other actions chosen from this state before. Choose a new action

Action Reasoning:
To start arranging the cars according to the desired goal state, we can move car_0 from behind car_2 in curb_0 to the empty curb_1. This ensures each car is at least in the correct curb temporarily and clears car_2, progressing us towards the goal state without breaking constraints.

New State Description:
Curb_0: car_2 is parked and now clear since car_0 has left. Curb_1: car_0 is parked and clear. Curb_2: car_1 is parked and clear. Curb_3: car_3 is parked and clear.

Action Chosen:
(move-car-to-curb car_0 car_2 curb_1)
