Parent State ID: 97
State Depth: 11
Action Taken: move-down-fast(fast1, n4, n0)
Action Reasoning: Move passenger p3 from floor 4 (n4) to floor 0 (n0) using fast1, as fast1 is available and can efficiently transport passengers to floors 0-4.
State Description: - fast0: Fast elevator at floor 3 (n3), 0/2 passengers, empty.- fast1: Fast elevator at floor 0 (n0), 0/2 passengers, empty.- slow0-0: Slow elevator at floor 1 (n1), 0/1 passengers, empty.- slow1-0: Slow elevator at floor 3 (n3), 0/1 passengers, empty.- p0: On floor 1 (n1).- p1: On floor 3 (n3), not on fast0.- p2: On floor 4 (n4).- p3: Moved to floor 0 (n0), preparing to leave elevator.- p4: On floor 1 (n1).- p5: On floor 2 (n2).
Action Path: ['board(p5, fast1, n3, 0, 1)', 'move-down-fast(fast1, n3, n2)', 'move-up-fast(fast0, n0, n1)', 'board(p1, fast0, n1, 0, 1)', 'move-up-fast(fast0, n1, n3)', 'leave(p1, fast0, n3, 1, 0)', 'leave(p5, fast1, n2, 1, 0)', 'move-up-fast(fast1, n2, n4)', 'move-down-fast(fast1, n4, n2)', 'move-up-fast(fast1, n2, n4)', 'move-down-fast(fast1, n4, n0)']

successfully verified the action of new state 116 with the path: The action `move-down-fast(fast1, n4, n0)` is valid as all preconditions are met: `fast1` was at `n4`, `n0` is below `n4`, and `n0` is reachable by `fast1`. The current state's natural language description and visualization accurately reflect the effects of the action and the sequence of actions taken. All objects from the initial state are present and correctly positioned in the visualization.
