Parent State ID: 48
State Depth: 7
Action Taken: board(p0, fast0, n1, 1, 2)
Action Reasoning: Passenger p0 is on floor 1 and needs to go to floor 0, which is reachable by the fast elevator. Boarding p0 onto fast0 decreases their outstanding task without overloading the elevator, moving them closer to the goal.
State Description: - fast0: Fast elevator at floor 3 (n3), now 2/2 passengers (contains p1 and p0).- fast1: Fast elevator at floor 2 (n2), 0/2 passengers, clear.- slow0-0: Slow elevator at floor 1 (n1), 0/1 passengers, clear.- slow1-0: Slow elevator at floor 3 (n3), 0/1 passengers, clear.- p0: On board fast0 at floor 3 (n3).- p1: On board fast0 at floor 3 (n3).- p2: On floor 4 (n4).- p3: On floor 4 (n4).- 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(p5, fast1, n2, 1, 0)', 'board(p0, fast0, n1, 1, 2)']

INACTIVE REASON: deactivated because diagram generation failed or invalid action chosen: Precondition violation: fast0 is not at floor 1 (n1).
