    In the theory of tractability of multivariate problems one usually studies problems with finite smoothness. Then we want to know which s-variate problems can be approximated to within ε by using, say, polynomially many in s and ε−1 function values or arbitrary linear ://

It is known that if 1 = 1 and 2 2(0;1) then n = o((lnn) 2), as n!1, is a necessary condition for a problem to be weakly tractable. We show this is a su cient condition as well.

These conditions are mainly given in terms of sums of certain functions depending on the singular values of the multivariate problem. They do not require the ordering of these singular values which in many cases is Erich Novak and Henryk Wozniakowski, Tractability of multivariate problems.

We assume that the domain space is a reproducing kernel Hilbert space so that function values are well defined. We prove QPT for algorithms that use only function values under the three assumptions: 1) the minimal errors for the univariate case decay Tractability of multivariate problems studies their complexity with respect to the number of variables, d, and the accuracy of the solution ε.

Different types of tractability have been used, such as polynomial tractability and weak tractability and others. These tractability types, however, do not express the complexity with respect to the We continue the study of generalized tractability initiated in our previous paper “Generalized tractability for multivariate problems, Part I: Linear tensor product problems and linear information”, J.
