To construct a Sobol’ sequence, a set of direction numbers vi,j needs to be selected. There is some freedom in the selection of initial direction numbers. Therefore, it is possible to receive different realisations of the Sobol’ sequence for selected dimensions. A bad selection of initial numbers can considerably reduce the efficiency of Sobol’ sequences when used for computation. Arguably the easiest choice for the initialisation numbers is just to have the l-th leftmost bit set, … WebSep 27, 2024 · (Note only methods that support this option will terminate the routine at precisely exact specified value.

WebThe generated sequences are converted from a uniform distribution to a Gaussian distribution. Following this conversion, around 68% of the values lie within one standard deviation, while two standard deviations account for around 95% and three account for 99.7%.
