Shifted Variable Metric Methods for Unconstrained Optimization
Lukšan, Ladislav ; Vlček, Jan
A family of shifted variable metric methods for unconstrained optimization is investigated. These methods form a basis for shifted limited-memory variable metric methods introduced in second contribution in proceedings of SANM 2003. We describe basic properties of these methods, establish their global convergence and give conditions for the superlinear rate of convergence. Their efficiency is demonstrated by using extensive numerical experiments.
New Limited-Memory Variable Metric Methods for Unconstrained Optimization
Vlček, Jan ; Lukšan, Ladislav
A new family of numerically efficient variable metric or quasi-Newton methods for unconstrained optimizaion is adapted for large-scale optimization. Global convergence of the method can be established for convex sufficiently smooth functions. Some encouraging numerical experience is reported. We refer to our report V-876 for proof and details.
Discrete Minimax Approximations with Application to Filter Design
Lukšan, Ladislav ; Vlček, Jan
The contribution contains a description of two different methods for discrete minimax approximation. These methods can be applied to electrical filter design. We demonstrate properties of these methods on the optimal design of a fourth order band-pass filter. Numerical results of our computational experiments and corresponding conclusions are presented.
