Error Message: Action not unique compared to other actions chosen from this state before. Choose a new action

Action Reasoning:
The best action is to board p1 onto fast1 at floor 1 since p1 needs to reach floor 1, which is convenient, and I've prioritizing emptying the floors and maximizing usage based on passenger destination. Our long-term plan is to move elevators efficiently to meet passengers’ destinations with minimal stops and transfers.

New State Description:
- fast0: At floor 5 (n5), 0/2 passengers.- fast1: At floor 1 (n1), 1/2 passenger.- slow0-0: At floor 2 (n2), 0/1 passengers.- p0: On floor 4 (n4).- p1: Boarded on fast1.- p2: On floor 5 (n5).- p3: On floor 4 (n4).- p4: On floor 2 (n2).- p5: On floor 0 (n0).- p6: On floor 2 (n2).

Action Chosen:
(board p1 fast1 n1 0 1)
