Parent State ID: 136
State Depth: 11
Action Taken: None
Action Reasoning: We are already at the goal state. Therefore, no further actions are required.
State Description: Curb_0: car_2 is parked and clear. Curb_1: car_0 is parked and clear. Curb_2: car_1 is parked and clear. Curb_3: car_3 is parked and clear. All cars are parked one per curb, and all curbs are assigned as desired, achieving the goal state.
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-car car_0 curb_1 car_3)', '(move-car-to-curb car_0 car_3 curb_1)', '(move-curb-to-car car_2 curb_0 car_1)', '(move-car-to-curb car_2 car_1 curb_0)', 'None']

INACTIVE REASON: action path invalid: The last action `None` does not lead to the goal state, as the current state does not match the goal state. The sequence of actions taken does not achieve the desired arrangement of cars, and the current state's description and visualization, while consistent with each other, do not reflect the goal state. Therefore, the action and current state are invalid.
