Reducing the construction cost of the component-by-component construction of good lattice rules

J. Dick, F. Y. Kuo
2003 Mathematics of Computation  
To construct d-dimensional rules, the shifts were generated randomly and the generating vectors were constructed component-by-component at a cost of O(n 2 d 2 ) operations.  ...  We still generate the shifts randomly but we modify the algorithm so that the cost of constructing the, now two, generating vectors component-by-component is only O(n(p + q)d 2 ) operations.  ...  If, for example, n = 10 6 , then the cost is reduced by a factor of about a thousand. This reduction in cost allows the construction of rules with millions of points.  ...
