Parent State ID: 10
State Depth: 5
Action Taken: (board p2 fast1 n4 n0 n1)
Action Reasoning: The next action in the plan is to board passenger p2 onto fast1 at floor n4. This aligns with the goal of moving p2 to floor n2, and fast1 is already at n4.
State Description: - fast0: At floor n0, 0/2 passengers.- fast1: At floor n4, 1/2 passengers (p2 on board).- slow0-0: At floor n0, 0/1 passengers.- slow1-0: At floor n3, 0/1 passengers.- p0: On floor n0.- p1: On floor n1.- p2: On board fast1.- p3: On floor n4.- p4: On floor n1.- p5: On floor n3.
Action Path: ['(board p0 slow0-0 n1 n0 n1)', '(move-down-slow slow0-0 n1 n0)', '(leave p0 slow0-0 n0 n1 n0)', '(move-up-fast fast1 n3 n4)', '(board p2 fast1 n4 n0 n1)']

successfully verified the action of new state 14 with the path: The action `(board p2 fast1 n4 n0 n1)` is valid as all preconditions are met: `fast1` is at `n4`, `p2` is at `n4`, and `fast1` has capacity. The effects are correctly reflected in the current state, with `p2` on board `fast1` and the passenger count updated. The natural language description, diagram encoding, and visualization accurately represent the current state.
