Parent State ID: 69
State Depth: 9
Action Taken: move-down-fast(fast1, n2, n0)
Action Reasoning: To better align with our goal state, I will move fast1 down to pick up passengers on lower floors. Fast1 is currently on floor 2 and has no passengers; it can move efficiently.
State Description: - fast0: Fast elevator at floor 3 (n3), 0/2 passengers, clear.- fast1: Fast elevator at floor 0 (n0), 0/2 passengers, clear.- slow0-0: Slow elevator at floor 1 (n1), 1/1 passengers, holding p4.- slow1-0: Slow elevator at floor 3 (n3), 0/1 passengers, clear.- p0: On floor 1 (n1), clear.- p1: On floor 3 (n3), clear.- p2: On floor 4 (n4), clear.- p3: On floor 4 (n4), clear.- p4: Onboard slow0-0 at floor 1 (n1).- p5: On floor 2 (n2), clear.
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(p5, fast1, n2, 1, 0)', 'leave(p1, fast0, n3, 1, 0)', 'board(p4, slow0-0, n1, 0, 1)', 'move-down-fast(fast1, n2, n0)']

successfully verified the action of new state 88 with the path: The last action `move-down-fast(fast1, n2, n0)` is valid as all preconditions are met: `fast1` is at floor 2 (n2), floor 0 (n0) is below floor 2, and `fast1` can reach floor 0. The current state's description and visualization accurately reflect the effects of the action and the sequence of actions taken. All objects are correctly represented, and the state is consistent with the goal requirements.
