It turns out that for some kinds of loads, we can't use bilinearity at all
to our benefit, so we spend almost all of our time trying to go through
each line to see how much we can save. Simply send in the minimum number
so far when doing this evaluation to begin with, which means we'll effectively
short-circuit the entire thing pretty fast once we find a line that can save
nothing.
