you're saying is that any computer solving most instance my problem just won't fit within the known universe okay that's a pretty good lower bound okay so that's the kind of thing we would like to have and so the circuit family is just some stepping stone to getting some non asymptotic things were just talking about numbers that is the ultimate goal we are really this is des soon okay all right so a lot of algorithms compared to circuit families okay so we define this thing how does it compare to the uniform
