Detailed Description

The triangular distribution Random Number Generator (RNG) that allows stream numbers to be set deterministically.

This class supports the creation of objects that return random numbers from a fixed triangular distribution. It also supports the generation of single random numbers from various triangular distributions.

The probability density depends on three parameters, the end points $a$ = Min and $b$ = Max, and the location of the peak or mode, $c$. For historical reasons this formulation uses the Mean, $\mu = \frac{(a + b + c)}{3}$ instead of the mode. In terms of the Mean, the mode is $c = 3 \mu - a - b$.

The probability is in the shape of a triangle defined on the interval $ x \in [a, b] $:

\[
     P(x; a, b, c) dx = \begin{array}{ll}
         0                                  &\mbox{ for $x \le a$} \\
         \frac{2(x - a)}{(b - a)(c - a)} dx &\mbox{ for $a \le x \le c$} \\
         \frac{2}{b - 1} dx                 &\mbox{ for $x = c$} \\
         \frac{2(b - x)}{(b - a)(b - c)} dx &\mbox{ for $c \le x \le b$} \\
         0                                  &\mbox{ for $b \le x$}
         \end{array}
  \]

The triangle RNG $x$ is generated by

\[
     x = \left\{ \begin{array}{rl}
         a + \sqrt{u (b - a) (c - a)} &\mbox{ if $u \le (c - a)/(b - a)$} \\
         b - \sqrt{(1 - u) (b - a) (b - c) } &\mbox{ otherwise}
         \end{array}
         \right.
  \]

where $u$ is a uniform random variable on [0,1).

Example

Here is an example of how to use this class:

double mean = 5.0;
double min = 2.0;
double max = 10.0;
x->SetAttribute ("Mean", DoubleValue (mean));
x->SetAttribute ("Min", DoubleValue (min));
x->SetAttribute ("Max", DoubleValue (max));
double value = x->GetValue ();
This class can be used to hold variables of floating point type such as 'double' or 'float'.
Definition double.h:31
Smart pointer class similar to boost::intrusive_ptr.
Ptr< T > CreateObject(Args &&... args)
Create an object by type, with varying number of constructor parameters.
Definition object.h:619
Antithetic Values.

If an instance of this RNG is configured to return antithetic values, the actual value returned, $x'$, is generated as follows:

\[
     x = \left\{ \begin{array}{rl}
         a + \sqrt{(1 - u) (b - a) (c - a)} &\mbox{ if $(1 - u) \le (c - a)/(b - a)$} \\
         b - \sqrt{u (b - a) (b - c) } &\mbox{ otherwise}
         \end{array}
         \right.
  \]

which now involves the distance $u$ is from 1.
