Parent State ID: 145
State Depth: 17
Action Taken: board(p4, fast0, n1, 1, 2)
Action Reasoning: Passenger p1 needs to reach floor 3 (n3) to fulfill one of the goals, and since fast0 is already at floor 1 with room for another passenger, we can board p4 onto fast0 and then move the elevator to floor 3.
State Description: - Elevator fast0 is at floor 1 (n1), with 2 passengers (p1 and 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 aboard fast0.- Passenger p2 is on floor 2 (n2).- Passenger p3 is on floor 0 (n0).- Passenger p4 is aboard fast0.- 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)', 'board(p3, fast0, n4, 0, 1)', 'move-down-fast(fast0, n4, n0)', 'leave(p3, fast0, n0, 1, 0)', 'move-up-fast(fast0, n0, n1)', 'board(p1, fast0, n1, 0, 1)', 'board(p4, fast0, n1, 1, 2)']

successfully verified the action of new state 158 with the path: The last action `board(p4, fast0, n1, 1, 2)` is valid as all preconditions are met: `fast0` is at floor `n1`, `p4` is at floor `n1`, and the capacity update is within limits. The current state's 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 the state is consistent with the goal of moving passengers to their target floors.
