Parent State ID: 1
State Depth: 2
Action Taken: (board p0 fast0 n4 0 1)
Action Reasoning: Passenger p0 on floor 4 can board the available fast elevator fast0, allowing us to move this passenger towards their destination. This action maximizes the use of fast elevators and reduces potential idle time.
State Description: - **fast0**: At floor 0 (n0), 1/2 passengers (p0 on board).- **fast1**: At floor 3 (n3), 1/2 passengers (p2 on board).- **slow0-0**: At floor 2 (n2), 0/1 passengers.- **p0**: On board fast0.- **p1**: On floor 1 (n1).- **p2**: On board fast1.- **p3**: On floor 4 (n4).- **p4**: On floor 2 (n2).- **p5**: On floor 5 (n5).- **p6**: On floor 2 (n2).
Action Path: ['(board p2 fast1 n3 0 1)', '(board p0 fast0 n4 0 1)']

INACTIVE REASON: deactivated because diagram generation failed or invalid action chosen: Elevator fast0 is not at the required floor (n4) for passenger p0 to board.
