introduces a new hyper-parameter minAcc, the percentage of
permitted noise is a much more intuitive hyper-parameter to
set up than the coverage breakpoint, since it is an structural
hyper-parameter of the problem, instead of being a hyperparameter of the system.
One interesting aspect to notice in Table 2 is that for problems with larger k, the heuristic seems to fail when the problem has either too many or too few terms. When the problem
has too many terms, it is possible to find representatives but
these representatives are likely to have a large k and this value
might not intersect with the other two areas, as it was exemplified in Figure 6. Moreover, if the problem has few terms finding a representative becomes very difficult and it is possible that
