Parent State ID: 93
State Depth: 12
Action Taken: move-down-fast(fast1, n4, n3)
Action Reasoning: Move fast1 down from n4 to n3 to do the shortest pickup of passenger p3, aiming to minimize costs.
State Description: - Elevator fast0 is at floor 0 (n0), empty, capacity 2.- Elevator fast1 is now at floor 3 (n3), empty, capacity 2.- Elevator slow0-0 is at floor 0 (n0), empty, capacity 1.- Elevator slow1-0 is at floor 2 (n2), empty, capacity 1.- Passenger p0 is on floor 0 (n0).- Passenger p1 is on floor 1 (n1).- Passenger p2 is on floor 2 (n2).- Passenger p3 is on floor 4 (n4), now at n3.- Passenger p4 is on floor 1 (n1).- 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(fast1, n2, n4)', 'move-down-fast(fast1, n4, n3)']

successfully verified the action of new state 106 with the path: The last action `move-down-fast(fast1, n4, n3)` is valid as all preconditions are met, and it aligns with the goal state requirements. The current state's natural language description and visualization are consistent with the sequence of actions taken, accurately reflecting the positions and statuses of all objects.
