Parent State ID: 117
State Depth: 13
Action Taken: move-down-fast(fast1, n4, n0)
Action Reasoning: Moving passenger p3 to their goal state by using available fast1 elevator will advance our goal, while minimizing waiting time for passengers.
State Description: - fast0: Fast elevator at floor 3 (n3), 0/2 passengers, empty.- fast1: Fast elevator at floor 0 (n0), 0/2 passengers.- 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).- p2: On floor 2 (n2).- p3: On floor 4 (n4), ready to board fast1.- 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)', 'board(p2, fast1, n4, 0, 1)', 'move-down-fast(fast1, n4, n2)', 'leave(p2, fast1, n2, 1, 0)', 'move-up-fast(fast1, n2, n4)', 'move-down-fast(fast1, n4, n0)']

successfully verified the action of new state 133 with the path: The action `move-down-fast(fast1, n4, n0)` is valid as all preconditions are met: `fast1` is at n4, n0 is below n4, and n0 is reachable. The effect of the action is correctly reflected in the current state. The natural language description, diagram encoding, and visualization accurately represent the current state, with all objects correctly positioned and described.
