    A stable family with high order of convergence for solving nonlinear equations 
    Cordero Barbero, Alicia; Lotfi, Taher; Mahdiani, Katayoun; Torregrosa Sánchez, Juan Ramón (Elsevier, 2015-03-01)
    [EN] Recently, Li et al. (2014) have published a new family of iterative methods, without memory, with order of convergence five or six, which are not optimal in the sense of Kung and Traub’s conjecture. Therefore, we ...

    New efficient methods for solving nonlinear systems of equations with arbitrary even order 
    Abbasbandy, Saeid; Bakhtiari, Parisa; Cordero Barbero, Alicia; Torregrosa Sánchez, Juan Ramón; Lotfi, Taher (Elsevier, 2016-09-05)
    In 2011, Khattri and Abbasbandy developed an optimal two-step Jarratt-like method for approximating simple roots of a nonlinear equation. We develop their method for solving nonlinear systems of equations. The main feature ...

    On generalization based on Bi et al. Iterative methods with eighth-order convergence for solving nonlinear equations 
    Lotfi, Taher; Cordero Barbero, Alicia; Torregrosa Sánchez, Juan Ramón; Abadi, Morteza Amir; Zadeh, Maryam Mohammadi (Hindawi Publishing Corporation, 2014)
    The primary goal of this work is to provide a general optimal three-step class of iterative methods based on the schemes designed by Bi et al. (2009). Accordingly, it requires four functional evaluations per iteration with ...

    Real and complex dynamics of iterative methods 
    Cordero Barbero, Alicia; Torregrosa Sánchez, Juan Ramón; Neta, Beny; Lotfi, Taher (Hindawi Publishing Corporation, 2016)

    Some new bi-accelerator two-point methods for solving nonlinear equations 
    Cordero Barbero, Alicia; Lotfi, Taher; Torregrosa Sánchez, Juan Ramón; Assari, Paria; Mahdiani, Katayoun (Springer Verlag (Germany), 2016-04)
    In this work, we extract some new and efficient two-point methods with memory from their corresponding optimal methods without memory, to estimate simple roots of a given nonlinear equation. Applying two accelerator ...

    Two optimal general classes of iterative methods with eighth-order 
    Cordero Barbero, Alicia; Lotfi, Taher; Mahdiani, Katayoun; Torregrosa Sánchez, Juan Ramón (Springer Verlag (Germany), 2014-12)
    Two new three-step classes of optimal iterative methods to approximate simple roots of nonlinear equations, satisfying the Kung-Traub's conjecture, are designed. The development of the methods and their convergence analysis ...

    Widening basins of attraction of optimal iterative methods 
    Bakhtiari, Parisa; Cordero Barbero, Alicia; Lotfi, Taher; Mahdiani, Katayoun; Torregrosa Sánchez, Juan Ramón (Springer-Verlag, 2017)
    [EN] In this work, we analyze the dynamical behavior on quadratic polynomials of a class of derivative-free optimal parametric iterative methods, designed by Khattri and Steihaug. By using their parameter as an accelerator, ...
