Hit Integration and Heaviside optimal seeds. The \(\int _{x}^{1}\) Hit Integration and \(\sum _{x}^{1}\) Heaviside optimal seeds, for single seeds of weight 11 and span \(\le 22\), over the match probability or the match frequency of each model (x-axis), and on any alignment length \(\ell \in [22\ldots64]\) (y-axis). On both Figs. 5 and 6, we choose to represent the same seeds with the same label and with the same background color. On discrete models, a pink mark is set. Seeds on the right of this mark are lossless for the two parameters indicated on the right margin: the minimum number of matches m over the alignment length \(\ell\)
