Parent State ID: 130
State Depth: 14
Action Taken: (board p3 fast1 n4 0 1)
Action Reasoning: Passenger p3 on floor 4 needs to get to floor 5. Fast1 is already on floor 4, so boarding p3 onto fast1 will efficiently move them closer to their goal.
State Description: - fast0: At floor 2 (n2), 0/2 passengers.- fast1: At floor 4 (n4), 1/2 passengers, with p3 onboard.- slow0-0: At floor 2 (n2), 0/1 passengers.- p0: On floor 2 (n2).- p1: On floor 1 (n1).- p2: On floor 5 (n5).- p3: Onboard fast1.- p4: On floor 2 (n2).- p5: On floor 0 (n0).- p6: On floor 2 (n2).
Action Path: ['(board p2 fast1 n3 0 1)', '(move-up-fast fast1 n3 n5)', '(move-up-fast fast0 n0 n1)', '(leave p2 fast1 n5 1 0)', '(board p5 fast1 n5 0 1)', '(move-down-fast fast1 n5 n0)', '(leave p5 fast1 n0 1 0)', '(move-up-fast fast0 n1 n2)', '(move-up-fast fast0 n2 n4)', '(board p0 fast0 n4 0 1)', '(move-down-fast fast0 n4 n2)', '(leave p0 fast0 n2 1 0)', '(move-up-fast fast1 n0 n4)', '(board p3 fast1 n4 0 1)']
