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.

that's not simply a-star
That's A-star with several targets. This precomputation thingie wont be usable for a big RTS game, with hundreds of objetcs, because it would require 128x128 (map size) layer for each object. And you have to update them in real time. That is why A-star wins.
