Vergleich von Abstiegsverfahren zur Nullstellenbestimmung bei Polynomen. (Comparison of descent methods for the calculation of zeros of polynomials)
The authors discuss the theoretical background and the implementation of global descent methods which are due to \textit{M. Kneser} [Math. Z. 177, 285-287 (1981; Zbl 0452.12007)], \textit{K. Nickel} [Numer. Math. 9, 80-98 (1966; Zbl 0154.168)] and \textit{St. Ruscheweyh} [ibid. 45, 227-240 (1984; Zbl 0553.65028)], respectively, for the calculation of the zeros of a complex polynomial. There is an extensive report on numerical experiments with these methods.
