Abstract
In DeVore et al. (2011) [7] we considered smooth functions on [0,1]N[0,1]N which depend on a much smaller number of variables ℓℓ or continuous functions which can be approximated by such functions. We were interested in approximating those functions when we can calculate point values at points of our choice. The number of points we needed for non-adaptive algorithms was higher than that in the adaptive case. In this paper we improve on DeVore et al. (2011) [7] and show that in the non-adaptive case one can use the same number of points (up to a multiplicative constant depending on ℓℓ) that we need in the adaptive case.
