OOP Anti-Objects

Has anybody heard of this anti-object concept in context to the OOP paradigm?

Wikipedia once had an article but like most good things it sometimes gets deleted.

any idea what modern rts games use when they have to deal with potentially thousands of units?

i suppose the "group" of units assigned to move somewhere could just detect the path once, and then have some kind of attraction/repulsion happening so that they move as a herd and not all over the exact same game tiles
