“…Today Smolyak's method is widely used in scientific computing and there exists a huge number of scientific articles dealing with applications and modifications of it. A partial list of papers (which is, of course, very far from being complete) on deterministic Smolyak algorithms may contain, e.g., the articles [64,65] for general approximation problems, [16,6,58,3,13,46,17,18,51,26,31] for numerical integration, [28,5,57,59,53,62,11] for function recovery, and [50,70,45,68,69,14,15] for other applications. Additional references and further information may be found in the survey articles [4,29], the book chapters [47,Chapter 15], [60,Chapter 4], and the books [7,12].…”
