question maybe it isn't I always thought it was a very interesting question turns out it actually is interesting for other reasons it actually is connected to circuit complexity but just the question of it you have us you have a silly algorithm you have a obvious algorithm is it the best you can do this is just a very fundamental question by itself all right so that's a quick introduction to circuits okay now I want to talk about how circuits compare to algorithms so in the usual everything model where you think of you know writing a single
