....by the number L i ) to use in each of them. Alternative approaches use information from the integrand to develop approximations of the integral in sub domains with a deterministic approach rather than with simulation. This is done in e.g. Berntsen, Espelid and Genz [2] Cools [5] Genz and Cools [10], and Press and Farrar [17] We represent the domain decomposition by a binary tree. Each leaf node in the tree corresponds to a distinct part of the domain, and when we expand the tree we divide the domain represented by a node in two parts of equal size. For one dimensional integrands, the ....
