Continued fraction real root isolation using the Hong root bound

An investigation of the codominance maximum computing time of the continued fractions method (CF) for isolation of the real roots of a squarefree integral polynomial when applied to the two-parameter family of polynomials Aa,n(x)=xn−2(ax2−(a+2)x+1)2, with n≥5 and a≥1. These polynomials have two roots, r1 and r2, in the interval (0,1), with |r1−r2|
