Artificial Intelligence or AI is the term used by the majority of participants in the forums to refer to that part of the underlying game code which controls the actions of swabbies. It is most often used to refer specifically to that portion of the code which controls the battle navigation of merchant, brigand, and barbarian ships.
AI may be confused with the term "non-player pirate". The difference is that AI refers to the game code used to give entities such as swabbies and ships a degree of autonomy. NPP on the other hand refers to any entities wholly controlled by AI, for instance swabbies and brigand ships.
