When generating multiple numerical columns, each of them will fill its one-dimensional space. However, if you want to cover a high-dimensional space, it is important that there are no uncovered areas. This can be achieved by quasirandom sequences. All dimensions will be in the interval from 0 to 1. By increasing the number of data points (with a larger input table), the "grid" of points in space gets finer. There are currently two methods provided: the Halton sequence generator and the Sobol sequence generator. Please note that the Halton generator only supports up to 40 dimensions and the Sobol generator up to 1000.
Generation is performed using the data generators provided by Apache Commons Math.
