Parent State ID: 115
State Depth: 14
Action Taken: move-up-fast(fast0, n1, n3)
Action Reasoning: Passenger p4 needs to reach floor 3, which is one stop above the current floor 1 where fast0 is located. Moving fast0 up to floor 3 and letting p4 leave will bring us closer to the goal state.
State Description: - Elevator fast0 is now at floor 3 (n3) with 1 passenger (p4), 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 elevator fast0, now at floor 3 (n3).- 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)', 'move-down-fast(fast0, n4, n1)', 'board(p4, fast0, n1, 0, 1)', 'move-up-fast(fast0, n1, n3)']

successfully verified the action of new state 130 with the path: The last action `move-up-fast(fast0, n1, n3)` is valid because all preconditions are satisfied: `fast0` is at `n1`, `n3` is above `n1`, and `n3` is reachable by `fast0`. The current state's description and visualization accurately reflect the effects of this action, with `fast0` at `n3` and `p4` on board. The state allows further actions to achieve the goal state, making the action logical and the state valid.
