Approximation of anisotropic classes by standard information
This paper deals with the approximation problem on anisotropic Besov classes (Sp0B)-B-r(R-d), p=(p(1), ..., p(d)), and Besov-Wiener classes (Spq0B)-B-r(R-d) using standard information. The asymptotic decay rates of the best algorithms in the worst-case setting are determined. (C) 2007 Elsevier Inc. All rights reserved.
