Parent State ID: 190
State Depth: 20
Action Taken: move-down-fast(fast0, n3, n1)
Action Reasoning: Passenger p4 needs to move from floor 1 to floor 3. Using fast0, currently on floor 3, is the best option to board p4 at floor 1 and then move to floor 3. We aim to move passengers efficiently to their goals.
State Description: - fast0: On floor 1 (n1), 0/2 passengers, empty.- fast1: On floor 0 (n0), 0/2 passengers, empty.- slow0-0: On floor 1 (n1), 0/1 passengers, empty.- slow1-0: On floor 3 (n3), 0/1 passengers, empty.- p0: On floor 0 (n0).- p1: On floor 3 (n3).- p2: On floor 2 (n2).- p3: On floor 0 (n0).- p4: On floor 1 (n1).- p5: On floor 2 (n2).

successfully verified the action of new state 199 with the path: The last action `move-down-fast(fast0, n3, n1)` is valid because all preconditions are satisfied: `fast0` is at `n3`, `n1` is below `n3`, and `n1` 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.
