Parent State ID: 134
State Depth: 16
Action Taken: move-up-fast(fast0, n1, n3)
Action Reasoning: Passenger p1 needs to be on floor 3. Fast elevator fast0 is already on floor 1 with p1, and it can quickly take p1 to floor 3.
State Description: - Elevator fast0 is at floor 3 (n3), empty, capacity 2.- Elevator fast1 remains at floor 2 (n2), empty, capacity 2.- Elevator slow0-0 remains at floor 0 (n0), empty, capacity 1.- Elevator slow1-0 remains at floor 2 (n2), empty, capacity 1.- Passenger p0 is on floor 0 (n0).- Passenger p1 is on floor 1 (n1).- Passenger p2 is on floor 2 (n2).- Passenger p3 is on floor 0 (n0).- Passenger p4 is on floor 1 (n1).- Passenger p5 is on floor 2 (n2).
Action Path: ['board(p0, slow0-0, n1, 0, 1)', 'move-down-slow(slow0-0, n1, n0)', 'leave(p0, slow0-0, n0, 1, 0)', 'board(p5, slow1-0, n3, 0, 1)', 'move-down-slow(slow1-0, n3, n2)', 'leave(p5, slow1-0, n2, 1, 0)', 'move-up-fast(fast1, n3, n4)', 'board(p2, fast1, n4, 0, 1)', 'move-down-fast(fast1, n4, n2)', 'leave(p2, fast1, n2, 1, 0)', 'move-up-fast(fast0, n0, n4)', 'board(p3, fast0, n4, 0, 1)', 'move-down-fast(fast0, n4, n0)', 'leave(p3, fast0, n0, 1, 0)', 'move-up-fast(fast0, n0, n1)', 'move-up-fast(fast0, n1, n3)']

successfully verified the action of new state 144 with the path: The last action `move-up-fast(fast0, n1, n3)` is valid as all preconditions are met: `fast0` is at floor 1, floor 3 is above floor 1, and floor 3 is reachable by `fast0`. The current state's description and visualization accurately reflect the sequence of actions taken, and all objects from the initial state are present.
