Parent State ID: 173
State Depth: 18
Action Taken: (move-up-fast fast0 n4 n5)
Action Reasoning: To bring p3 to its destination, move fast0 with p3 from n4 to n5, where p2 currently is. This optimizes p3's move while keeping fast elevations full.
State Description: - **fast0**: At floor 5 (n5), 1/2 passengers, with p3 on board.- **fast1**: At floor 1 (n1), 0/2 passengers, ready for passenger p1 to board.- **slow0-0**: At floor 2 (n2), 0/1 passengers, empty.- **p0**: On floor 2 (n2).- **p1**: On floor 1 (n1).- **p2**: On floor 5 (n5).- **p3**: On board fast0 at floor 5 (n5).- **p4**: On floor 4 (n4), at their destination.- **p5**: On floor 0 (n0), at their destination.- **p6**: On floor 2 (n2).

successfully verified the action of new state 185 with the path: The last action is valid because all preconditions are satisfied: `fast0` is at n4, n5 is above n4, and n5 is reachable by `fast0`. 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 correctly visualized in the current state.
