You’re changing the subject! There is a really good problem in there. Why does this stuff work so well, for what classes of problems, and can we say anything about the fundamental energy/accuracy limits of this approach? I think of it as an engineering problem, but there are mathematical rephrasings of this problem, as Michel Talagrand’s work has shown. Don’t let the greed/stampede obscure the very interesting technical principles here.
