A major AI challenge for entity-level military simulations (i.e. simulations of individual soldiers, vehicles, etc.) and computer games is efficiently determining which entitites on a virtual battlefield can see each other.. Entity inter-visibility is traditionally modeled by tracing a line of sight (LOS), i.e. entity A sees entity B if the line segment between A's eyes and the top of B is unobstructed. This model is, however, highly inaccurate. Computing lines of sight to multiple points on the target entity improves accuracy, but at the cost of futher loading the CPU...(see document for continuation)

Creation of a computer generated semi-autonomous entity able to function in an amphibious environment Sobey, Thomas Jay. (Monterey, California. Naval Postgraduate School, 1995-09);The problem is that current programs used to generate Semi-Automated Forces (SAF) are unable to fully simulate amphibious military operations in littoral regions. SAF development has focused on three separate paradigms: ...
