Influence of number of repeats r over selectiveness and running time. Influence of number of repeats r over selectiveness and running time. Human Chromosome 22 with parameters (L, d, r) = (260, 13, r) with q = 14. The selectiveness of 0 obtained for methods GOOD and EXCELLENT are not drawn on the log scale. As r grows, the selectiveness decreases because more frequent repeats are rarer than the less frequent ones. Also, variant FINE gets less selective as r increases. Moreover, this illustrates a case in which EXCELLENT is time consuming while not bringing an improvement on the selectiveness with respect to GOOD as we could see also in Figure 5 and Table 2.
