Abstract
In this work we obtain an asymptotic estimate for the expected number of maxima of the random algebraic polynomial \(a_0 + a_1 x + a_2 x^2 + \cdots + a_{n - 1} x^{n - 1} \), where a j (j=0, 1,...,n−1) are independent, normally distributed random variables with mean μ and variance one. It is shown that for nonzero μ, the expected number of maxima is asymptotic to \(((\sqrt 3 + 1)/4\pi )\)log n, when n is large.
