Abstract

We consider the order of convergence for linear and nonlinear Monte Carlo approximation of compact embeddings from Sobolev spaces of dominating mixed smoothness defined on the torus Td\mathbb{T}^d into the space L(Td)L_{\infty}(\mathbb{T}^d) via methods that use arbitrary linear information. These cases are interesting because we can gain a speedup of up to 1/21/2 in the main rate compared to the worst case approximation. In doing so we determine the rate for some cases that have been left open by Fang and Duan.
