    • 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

    • getFibonacciRank

    • fibonacci

      public static final int fibonacci(int k)

    • fibonacciLattice

      public static final double fibonacciLattice(int k, int i, int d)

    • reducedCPRotation

      public static final double reducedCPRotation(int k, int d, double x0, double x1)

    • korobovLattice

      public static final double korobovLattice(int m, int i, int d)
