Robust preconditioners for the matrix free truncated Newton method. (English). In: Chleboun, J., Přikryl, P., Segeth, K. and Šístek, J. (eds.): Programs and Algorithms of Numerical Mathematics. Proceedings of Seminar. Dolní Maxov, June 6-11, 2010. Institute of Mathematics AS CR, Prague, 2010. pp. 137-151
MSC: 65F08, 65K05, 65Y20, 90C30
Keywords:
unconstrained minimization; truncated Newton method; preconditioned conjugate gradient method
Summary:
New positive definite preconditioners for the matrix free truncated Newton method are given. Corresponding algorithms are described in detail. Results of numerical experiments that confirm the efficiency and robustness of the preconditioned truncated Newton method are reported.
