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
- indexorder
-
- Returns:
- sigma function
