Optimality parameter of Korobov parallelepipedal grids for cubature formulas
Victor Alexeevich Bykovskii, S. V. Gassan · Computational Mathematics and Mathematical Physics · 2011
When multiple integrals are approximately evaluated using Korobov cubature formulas, it is necessary to introduce a parameter characterizing the uniform distribution of the grid nodes. A new parameter for Korobov parallelepipedal grids is proposed, and an algorithm for its computation is described.
