      5 The paper [jerrum1986random] that defines it shows equivalence of [counting_approximate] and [sampling_approximate]
      6 - it also shows that [counting_approximate] to within a constant factor allows you, for self-reducible problems, to do [counting_approximate] with a [fpras], by going via [sampling_approximate]
