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

Action Reasoning:
To align car_2 with its goal curb, I will first clear car_1 by moving car_2 to the available curb_1. This allows car_1 to become clear and retrievable for positioning in its goal spot, maintaining maximum flexibility for rearranging the cars.

New State Description:
Curb_0: Contains car_0, clear. Curb_1: Contains car_2, clear. Curb_2: Contains car_1, clear. Curb_3: Contains car_3, clear. Car_0: Parked and clear in curb_0. Car_1: Parked and clear in curb_2. Car_2: Parked and clear in curb_1. Car_3: Parked and clear in curb_3.

Action Chosen:
