Thinking about garbage collection: is there any graph theory analog to the Fourier Transform? A new space derived from the objects-and-references space which enables asymptotically more efficient determination or update of liveness? Bloom filter mojo?

Replying to @JonOlick
UObject base layout did this in the early days. Doesn’t scale well to inheritance, though, and automatic sequential prefetching by the CPU seems to help. Really the problem with Unreal GC isn’t the amortized overhead - like 0.1%, it’s the single-threaded pause time.
