Conjugate direction methods for solving systems of equations and finding saddle points. Part 2
Computing Center, USSR Academy of Sciences, Moscow.ORCID iD: 0000-0003-1836-4200
1982 (English)In: Engineering Cybernetics, ISSN 0013-788X, Vol. 20, no 4, 23-31 p.Article in journal (Refereed) Published
Abstract [en]

This article is the second part of a paper devoted to the development of methods of pseudo-orthogonal directions for solving systems of nonlinear equations (for part I see Eng. Cybern. 1982, Vol. 20, No. 3, p. 13-19). An approach is developed for studying the reate of convergence of such methods. Local quadratic convergence of the proposed methods to the solution of the system of equations is proven. This implies the quadratic convergence of some methods of unconstrained minimization: the method of parallel displacements, Zangull's method, and Powell's method.
