Parent State ID: 72
State Depth: 7
Action Taken: (move-curb-to-curb car_2 curb_0 curb_3)
Action Reasoning: I will move car_2 to an empty curb, curb_3, using move-curb-to-curb. This frees curb_0 for car_0, moving closer to the goal.
State Description: Curb_0: Empty and clear.  Curb_1: Car_0 is parked and clear.  Curb_2: Car_1 is parked and clear.  Curb_3: Car_2 is parked and clear.  Car_1: Parked at curb_2, clear.  Car_0: Parked at curb_1, clear.  Car_2: Parked at curb_3, clear.  Car_3: Parked at curb_3, remained parked there earlier.
Action Path: ['(move-curb-to-curb car_3 curb_2 curb_3)', '(move-car-to-curb car_1 car_2 curb_2)', '(move-curb-to-car car_0 curb_1 car_2)', '(move-car-to-curb car_0 car_2 curb_1)', '(move-curb-to-car car_0 curb_1 car_2)', '(move-car-to-curb car_0 car_2 curb_1)', '(move-curb-to-curb car_2 curb_0 curb_3)']

INACTIVE REASON: deactivated because diagram generation failed or invalid action chosen: Curb_3 is not clear, violating preconditions and goal state constraints.
