The acronym AI has been used in game dev for ages to describe things like pathing and simulation which are almost invariably algorithms (such as A* used for autonomous entities to find a path to a specific destination) or emergent behaviours (which are also algorithms were simple rules are applied to individual entities - for example each bird on a flock - to create a complex whole from many such simple agents, and example of this in gamedev being Steering Behaviours, outside gaming it would be the Game Of Life).
