Example text

Consider multivariate approximation APP D fAPPd g as defined in this section for the class ƒstd and for the normalized error criterion. • Verify whether multivariate approximation is quasi-polynomially tractable. If so find the exponent of quasi-polynomial tractability. • If multivariate approximation is not quasi-polynomially tractable, verify whether it is weakly tractable or if the curse of dimensionality is present. We end this section by a remark on the rate of convergence similarly as we did in the previous section.

1 of the univariate eigenvalues is positive and the second largest univariate eigenvalue ;2 is strictly less than the largest univariate eigenvalue ;1 . If so, then the exponent of quasi-polynomial tractability is  t all D max 2 ; r ln à 2 ;1 = : ;2 In our case, r D 1 and t all D 2 ln ;1 = D ;2 2 D ln ! "; Hd / follow from the definition of quasi-polynomial tractability. This completes the proof. 7 states that we lose polynomial tractability for the normalized error criterion although even strong polynomial tractability is present for the absolute error criterion.
