Parent State ID: 83
State Depth: 11
Action Taken: move-up-fast(fast0, n0, n4)
Action Reasoning: Passenger p3 needs to move from floor 4 to floor 0. Using fast0, which is currently on floor 0 and has capacity, will efficiently bring p3 to their destination with minimal cost.
State Description: - Elevator fast0 is now at floor 4 (n4), 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 4 (n4).- 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)']

successfully verified the action of new state 91 with the path: The last action `move-up-fast(fast0, n0, n4)` is valid because all preconditions are satisfied: `fast0` was at `n0`, `n4` is above `n0`, and `n4` is reachable by `fast0`. The current state's description and visualization accurately reflect the effects of the action and the positions of all objects. The action logically progresses towards the goal state by positioning `fast0` to potentially pick up `p3` at `n4`.
