Parent State ID: 119
State Depth: 13
Action Taken: (move-up-slow slow0-0 n3 n4)
Action Reasoning: To advance towards the goal state, we should move p4, who is on board the slow elevator, to their destination on floor 4. This will free up the slow elevator to assist other passengers.
State Description: - **fast0**: At floor 4 (n4), 0/2 passengers.- **fast1**: At floor 1 (n1), 0/2 passengers.- **slow0-0**: At floor 4 (n4), 1/1 passenger with p4 on board.- **p0**: On floor 4 (n4).- **p1**: On floor 1 (n1).- **p2**: On floor 5 (n5).- **p3**: On floor 4 (n4).- **p4**: On board slow0-0.- **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)', '(move-up-fast fast1 n0 n1)', '(board p4 slow0-0 n2 0 1)', '(move-up-slow slow0-0 n2 n3)', '(move-up-slow slow0-0 n3 n4)']

INACTIVE REASON: action path invalid: The last action `(move-up-slow slow0-0 n3 n4)` is invalid because the precondition that `slow0-0` can reach `n4` from `n3` is not satisfied. The current state's description and visualization are mostly accurate, but the position of `slow0-0` at `n4` is incorrect due to the invalid action.
