Webroot squaring is proposed. He seems to consider it important that although Lobacevskil's Algebra [6] bears the date 1834, it was actually in the hands of the censor in 1832. But he builds his case upon the assertion that Dandelin's paper was concerned primarily with Newton's method, and that root squaring is In mathematics, Graeffe's method or Dandelin–Lobachesky–Graeffe method is an algorithm for finding all of the roots of a polynomial. It was developed independently by Germinal Pierre Dandelin in 1826 and Lobachevsky in 1834.

WebFeb 1, 1998 · The Graeffe's root squaring technique offers some inherent parallelism in computing the new coefficients at each step of iteration, and also in finding all the roots at the final step. In this paper, we propose two parallel algorithms exploiting this parallelism on two different architectures using mesh of trees and multitrees, respectively.
