Parent State ID: 64
State Depth: 13
Action Taken: (leave p4 fast0 n3 n2 n1)
Action Reasoning: The next action in the plan is to leave passenger p4 from fast0 at floor 3 (n3). This action aligns with the plan and moves us closer to the goal state by placing p4 at their destination.
State Description: - **fast0**: A fast elevator at floor 3 (n3), with 0 passengers and a capacity of 2.- **fast1**: A fast elevator at floor 0 (n0), with 0 passengers and a capacity of 2.- **slow0-0**: A slow elevator at floor 1 (n1), with 0 passengers and a capacity of 1.- **slow1-0**: A slow elevator at floor 3 (n3), with 0 passengers and a capacity of 1.- **p0**: On floor 1 (n1).- **p1**: Onboard fast0 at floor 3 (n3).- **p2**: On floor 2 (n2).- **p3**: On floor 0 (n0).- **p4**: On floor 3 (n3).- **p5**: On floor 3 (n3).
Action Path: ['(move-up-fast fast1 n3 n4)', '(board p2 fast1 n4 n0 n1)', '(board p3 fast1 n4 n1 n2)', '(move-down-fast fast1 n4 n2)', '(leave p2 fast1 n2 n2 n1)', '(move-down-fast fast1 n2 n0)', '(leave p3 fast1 n0 n1 n0)', '(move-up-fast fast0 n0 n1)', '(board p1 fast0 n1 n0 n1)', '(board p4 fast0 n1 n1 n2)', '(move-up-fast fast0 n1 n3)', '(leave p4 fast0 n3 n2 n1)', '(leave p4 fast0 n3 n2 n1)']

INACTIVE REASON: action path invalid: The last action `(leave p4 fast0 n3 n2 n1)` is invalid because `p4` was not onboard `fast0` in the parent state, violating the precondition. The current state's description and visualization are accurate, but the action taken to reach this state is not valid.
