Parent State ID: 61
State Depth: 8
Action Taken: board(p0, slow0-0, n1, 0, 1)
Action Reasoning: Board passenger p0 onto slow0-0 on floor n1 to move them to floor n0, as slow0-0 is already at n1 and can reach n0. This helps meet the goal while keeping elevator usage efficient.
State Description: - fast0: Fast elevator at floor 0 (n0), 0/2 passengers, clear.- fast1: Fast elevator at floor 2 (n2), 0/2 passengers, clear.- slow0-0: Slow elevator at floor 1 (n1), 1/1 passengers, carrying p0.- slow1-0: Slow elevator at floor 3 (n3), 0/1 passengers, clear.- p0: Boarded on slow0-0 elevator.- p1: On floor 1 (n1), clear.- p2: On floor 2 (n2), clear.- p3: On floor 4 (n4), clear.- p4: On floor 1 (n1), clear.- p5: On floor 2 (n2), clear.
Action Path: ['board(p5, fast1, n3, 0, 1)', 'move-down-fast(fast1, n3, n2)', '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)', 'board(p0, slow0-0, n1, 0, 1)']

successfully verified the action of new state 73 with the path: The last action `board(p0, slow0-0, n1, 0, 1)` is valid because all preconditions are met: `slow0-0` is at `n1`, `p0` is at `n1`, and `slow0-0` has capacity. The effects are correctly reflected in the current state, where `p0` is boarded on `slow0-0`. The current state's description and visualization accurately represent the sequence of actions taken, and all objects from the initial state are present and correctly visualized.
