Convergence Acceleration by Extraction of Linear Subsequences
Claude Brezinski, Jean-Paul Delahaye, B. Germain-Bonne · SIAM Journal on Numerical Analysis · 1983
Logarithmic sequences are usually difficult to accelerate. In this paper we show how to extract a subsequence converging linearly. This subsequence can be easily accelerated by classical algorithms. Theoretical results are given as well as an algorithmic extraction procedure. Numerical examples illustrate the results.
