Parent State ID: 70
State Depth: 9
Action Taken: move-down-fast(fast0, n3, n1)
Action Reasoning: To minimize elevator usage and costs, move fast0 from floor 3 to floor 1 to pick up passengers p0 and p4. This utilizes the fast elevator's ability to reach the floor efficiently.
State Description: - fast0: Fast elevator at floor 1 (n1), 0/2 passengers, clear.- fast1: Fast elevator at floor 2 (n2), 0/2 passengers, clear.- slow0-0: Slow elevator at floor 0 (n0), 0/1 passengers, clear.- slow1-0: Slow elevator at floor 3 (n3), 0/1 passengers, clear.- p0: On floor 1 (n1), clear.- p1: On floor 3 (n3), clear.- p2: On floor 4 (n4), 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)', 'move-up-fast(fast0, n0, n1)', 'board(p1, fast0, n1, 0, 1)', 'move-up-fast(fast0, n1, n3)', 'leave(p5, fast1, n2, 1, 0)', 'leave(p1, fast0, n3, 1, 0)', 'move-down-slow(slow0-0, n1, n0)', 'move-down-fast(fast0, n3, n1)']

successfully verified the action of new state 91 with the path: The action `move-down-fast(fast0, n3, n1)` is valid as all preconditions are satisfied: `fast0` was at floor 3, floor 1 is below floor 3, and floor 1 is reachable by `fast0`. The current state's description and visualization accurately reflect the effects of the actions taken, including the position of `fast0` at floor 1. All elements from the initial state are present in the current state's visualization.
