Parent State ID: 11
State Depth: 4
Action Taken: move-up-fast(fast1, n2, n4)
Action Reasoning: Moving fast1 to floor 4 allows p2 and p3 to board and reach floor 2, aligning with the goal state.
State Description: - fast0: Fast elevator at floor 0 (n0), 0/2 passengers.- fast1: Fast elevator at floor 4 (n4), 0/2 passengers, clear.- slow0-0: Slow elevator at floor 1 (n1), 0/1 passengers.- slow1-0: Slow elevator at floor 3 (n3), 0/1 passengers.- p0: On floor 1 (n1).- p1: On floor 1 (n1).- p2: On floor 4 (n4).- p3: On floor 4 (n4).- p4: On floor 1 (n1).- p5: On floor 2 (n2), clear.
Action Path: ['board(p5, fast1, n3, 0, 1)', 'move-down-fast(fast1, n3, n2)', 'leave(p5, fast1, n2, 1, 0)', 'move-up-fast(fast1, n2, n4)']

successfully verified the action of new state 22 with the path: The action `move-up-fast(fast1, n2, n4)` is valid as all preconditions are met: `fast1` is at `n2`, `n4` is above `n2`, and `fast1` can reach `n4`. The current state's description and visualization accurately reflect the effects of the action, and all objects from the initial state are present. The action positions the elevator for future moves towards the goal state.
