An Optimal Order Method for Multiple Roots in Case of Unknown Multiplicity [PDF]

open access: yesAlgorithms, 2016
In the literature, recently, some three-step schemes involving four function evaluations for the solution of multiple roots of nonlinear equations, whose multiplicity is not known in advance, are considered, but they do not agree with Kung–Traub’s ...
