Parent State ID: 106
State Depth: 12
Action Taken: move-up-fast(fast1, n2, n4)
Action Reasoning: Passenger p3 needs to reach floor 0, so let's move fast1 to floor 4 to board p3. This aligns with our goal to transport passengers efficiently using the fast elevator.
State Description: - fast0: Fast elevator at floor 3 (n3), 0/2 passengers, empty.- fast1: Fast elevator at floor 4 (n4), 0/2 passengers, ready to board p3.- slow0-0: Slow elevator at floor 1 (n1), 0/1 passengers, empty.- slow1-0: Slow elevator at floor 3 (n3), 0/1 passengers, empty.- p0: On floor 1 (n1).- p1: On floor 3 (n3).- p2: On floor 2 (n2).- p3: On floor 4 (n4), ready to board fast1.- p4: On floor 1 (n1).- p5: On floor 2 (n2).
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(p1, fast0, n3, 1, 0)', 'leave(p5, fast1, n2, 1, 0)', 'move-up-fast(fast1, n2, 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)']

successfully verified the action of new state 117 with the path: The last action `move-up-fast(fast1, n2, n4)` is valid as all preconditions are met, and the effects are correctly reflected in the current state. The current state's description and visualization accurately represent the sequence of actions taken from the initial state.
