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
