چکیده
|
The point single-step ps1 procedure established by alefeld and herzberger (1974) has r-order of convergence greater than 2. this method is modified by using the idea of aitken (1950). the modified method pss1 has a faster convergence rate. in this paper, the convergence analysis of the point symmetric single-step pss1 is shown. the interval version of pss1 (i.e. the interval symmetric single-step iss1) is given in monsi and wolfe (1988). computational results indicate that this method is more efficient than the total-step (kerner (1966)) and the single-step (alefeld and herzberger (1974)) methods
