> So far we sort the search space by (1) sorting cutsets by their scores, and (2) appending
all other interesting points in an ordered manner. This task aims to append all other interesting
points sorted by their size of intermediates. Having large materializations higher in the
tree increases the chances of pruning large sub areas of the search space.
