Parent State ID: 9
State Depth: 3
Action Taken: (move-down-fast fast1 n3 n0)
Action Reasoning: An optimal next step is to move `fast1` from floor 3 to floor 0 to pick up `p5`, reducing onboard waiting time for `p2` while helping achieve the final state.
State Description: - Fast elevator `fast0` is at floor 0 with 0 passengers out of 2.- Fast elevator `fast1` is now at floor 0 still carrying `p2`, 1 passenger out of 2.- Slow elevator `slow0-0` is on floor 2 with `p4` onboard, full capacity at 1/1.- Passenger `p0` is on floor 4.- Passenger `p1` is on floor 1.- Passenger `p2` is onboard `fast1`, now at floor 0.- Passenger `p3` is on floor 4.- Passenger `p5` is on floor 5.- Passenger `p6` is on floor 2.
Action Path: ['(board p4 slow0-0 n2 0 1)', '(board p2 fast1 n3 0 1)', '(move-down-fast fast1 n3 n0)']

INACTIVE REASON: deactivated because diagram generation failed or invalid action chosen: Action does not bring `p2` closer to its goal floor (n5).
