Parent State ID: 13
State Depth: 4
Action Taken: board(p1, fast0, n1, 0, 1)
Action Reasoning: Passenger p0, p1, and p4 need to be moved, and using fast0 now minimizes travel cost and time. Loading p1 for its optimal stop at floor 3 aligns well with the goal.
State Description: - Fast0 is at floor 1 with 1 passenger (max capacity 2), carrying p1.- Fast1 is at floor 2 with 0 passengers (max capacity 2).- Slow0-0 is at floor 1 with 0 passengers (max capacity 1).- Slow1-0 is at floor 3 with 0 passengers (max capacity 1).- Passenger p0 is on floor 1.- Passenger p1 is boarded on fast0.- Passenger p2 is on floor 4.- Passenger p3 is on floor 4.- Passenger p4 is on floor 1.- Passenger p5 is on floor 2.- Travel cost is 4 units.
Action Path: ['board(p5, fast1, n3, 0, 1)', 'move-down-fast(fast1, n3, n2)', 'leave(p5, fast1, n2, 1, 0)', 'board(p1, fast0, n1, 0, 1)']

INACTIVE REASON: deactivated because diagram generation failed or invalid action chosen: Fast0 is not at floor 1, violating the precondition for boarding.
