Kunsch", "Daniel Rudolf" ], "comment": "23 pages", "categories": [ "math.NA" ], "abstract": "We study the complexity of approximating integrals of smooth functions at absolute precision $\\varepsilon > 0$ with confidence level $1 - \\delta \\in (0,1)$. The optimal error rate for multivariate functions from classical isotropic Sobolev spaces $W_p^r(G)$ with sufficient smoothness on bounded Lipschitz domains $G \\subset \\mathbb{R}^d$ is determined. It turns out that the integrability index $p$ has an effect on the influence of the uncertainty $\\delta$ in the complexity. In the limiting case $p = 1$ we see that deterministic methods cannot be improved by randomization. In general, higher smoothness reduces the additional effort for diminishing the uncertainty. Finally, we add a discussion about this problem for function spaces with mixed smoothness.", "revisions": [ { "version": "v1", "updated": "2018-09-26T10:25:41.000Z" } ], "analyses": { "subjects": [ "65C05", "65D30", "65J05" ], "keywords": [ "monte carlo integration", "smooth functions", "optimal confidence", "classical isotropic sobolev spaces", "optimal error rate" ], "note": { "typesetting": "TeX", "pages": 23, "language": "en", "license": "arXiv", "status": "editable" } } }
