Parent State ID: 2
State Depth: 2
Action Taken: (move-up-fast fast0 n0 n4)
Action Reasoning: Fast0 should move to floor 4 to pick up p0 and p3, reducing waiting time and optimizing capacity.
State Description: - Fast elevator fast0 is at floor 4 with 0/2 passengers.- Fast elevator fast1 is at floor 3 with 0/2 passengers.- Slow elevator slow0-0 is at floor 2 with 1/1 passenger (p4 onboard).- Passenger p0 is on floor 4.- Passenger p1 is on floor 1.- Passenger p2 is on floor 3.- Passenger p3 is on floor 4.- Passenger p5 is on floor 5.- Passenger p6 is on floor 2.
Action Path: ['(board p4 slow0-0 n2 0 1)', '(move-up-fast fast0 n0 n4)']
