      • riVDC

        public static double riVDC​(int bits,
                                   int r)
      • riS

        public static double riS​(int i,
                                 int r)
      • riLP

        public static double riLP​(int i,
                                  int r)
      • halton

        public static final double halton​(int d,
                                          int i)
      • mod1

        public static final double mod1​(double x)
        Compute mod(x,1), assuming that x is positive or 0.
        Parameters:
        x - any number >= 0
        Returns:
        mod(x,1)
      • sigma

        public static final int sigma​(int i,
                                      int order)
        Compute sigma function used to seed QMC sequence trees. The sigma table is exactly 2^order elements long, and therefore i should be in the: [0, 2^order) interval. This function is equal to 2^order*halton(0,i)
        Parameters:
        i - index
        order -
        Returns:
        sigma function
