This paper addresses the problem of defining a smart, more challenging, and natural movement model for NPCs. ...
Unfortunately, standard NPCs behavior, i.e., patrolling between rally points, does not put a significant challenge to players once its deterministic movement pattern is discovered. ...
In particular, mobs (shorthand for "mobiles") are NPCs roaming the map and typically implement monsters to be defeated or avoided. ...
