Parent State ID: 21
State Depth: 5
Action Taken: board(p1, fast0, n1, 0, 1)
Action Reasoning: To move passengers p1 and p4 closer to their goal floors, use fast0 to pick them from floor 1 and take them to floor 3. This reduces total waiting time and transitions them directly to their target floor.
State Description: - Elevator fast0 is at floor 0 (n0), with passenger p1 onboard, capacity 1/2.- Elevator fast1 remains at floor 4 (n4), empty, capacity 0/2.- Elevator slow0-0 is at floor 0 (n0), empty, capacity 0/1.- Elevator slow1-0 is at floor 3 (n3), empty, capacity 0/1.- Passenger p0 is on floor 0 (n0).- Passenger p1 is onboard fast0.- Passenger p2 stays on floor 4 (n4).- Passenger p3 remains on floor 4 (n4).- Passenger p4 is on floor 1 (n1).- Passenger p5 is on floor 3 (n3).
Action Path: ['board(p0, slow0-0, n1, 0, 1)', 'move-down-slow(slow0-0, n1, n0)', 'leave(p0, slow0-0, n0, 1, 0)', 'move-up-fast(fast1, n3, n4)', 'board(p1, fast0, n1, 0, 1)']

INACTIVE REASON: deactivated because diagram generation failed or invalid action chosen: Elevator fast0 is not at the required floor n1 for boarding p1.
