Bernoulli and Hit Integration polynomials. The Bernoulli and \(\int _0^x\) Hit Integration polynomials plots for the contiguous seed and the Patternhunter I spaced seed, on alignments of length \(\ell =64\). The two polynomials have been plotted according to their respective formulas (1) and (2). A vertical mark indicates where they cross each other in the range \(x \in \, ]0,1[\) : the contiguous seed is better under this marked value; otherwise, the Patternhunter I spaced seed is better
