Abstract: | Mauduit and Sárközy introduced and studied certainnumerical parameters associated to finite binary sequences EN {–1, 1}N in order to measure their level of randomness.Those parameters, the normality measure (EN), the well-distributionmeasure W(EN), and the correlation measure Ck(EN) of order k,focus on different combinatorial aspects of EN. In their work,amongst others, Mauduit and Sárközy (i) investigatedthe relationship among those parameters and their minimal possiblevalue, (ii) estimated (EN), W(EN) and Ck(EN) for certain explicitlyconstructed sequences EN suggested to have a pseudorandomnature, and (iii) investigated the value of those parametersfor genuinely random sequences EN. In this paper, we continue the work in the direction of (iii)above and determine the order of magnitude of (EN), W(EN) andCk(EN) for typical EN. We prove that, for most EN {–1,1}N, both W(EN) and (EN) are of order N, while Ck(EN) is oforder for any given 2 k N/4. |
