Parent State ID: 72
State Depth: 7
Action Taken: (move-curb-to-curb car_1 curb_2 curb_1)
Action Reasoning: To achieve the goal, car_1 needs to be moved to curb_1. Moving car_1 directly to curb_1 is logical because car_1 is on curb_2, which could then accommodate car_2, allowing definite progress toward the goal configuration.
State Description: Curb_0: car_2 remains parked and clear. Curb_1: car_1 is now parked and clear. Curb_2: Now empty and clear. Curb_3: car_3 is parked and clear. All actions align further with completing the target parking state within constraints.
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_1 curb_2 curb_1)']

INACTIVE REASON: deactivated because diagram generation failed or invalid action chosen: curb_1 is not empty, violating precondition for move-curb-to-curb.
