Description

Instatiations of linear_feedback_shift model a pseudo-random number generator . It was originally proposed in

"Random numbers generated by linear recurrence modulo two.", Tausworthe, R. C.(1965), Mathematics of Computation 19, 201-209.

`linear_feedback_shift_engine` public static functions

```
 ();
```
Returns the smallest value that the generator can produce.
```
 ();
```
Returns the largest value that the generator can produce.

`linear_feedback_shift_engine` public member functions

```
();
```
Constructs a linear_feedback_shift_engine, using the default seed.
```
( s0);
```
Constructs a linear_feedback_shift_engine, seeding it with s0.
```
template<typename SeedSeq> 
  ( seq);
```
Constructs a linear_feedback_shift_engine, seeding it with seq.
```
template<typename It> ( first,  last);
```
Constructs a linear_feedback_shift_engine, seeding it with values from the range [first, last).
```
 ();
```
Seeds a linear_feedback_shift_engine with the default seed.
```
 ( s0);
```
Seeds a linear_feedback_shift_engine with s0.
```
template<typename SeedSeq>  ( seq);
```
Seeds a linear_feedback_shift_engine with values produced by seq.generate().
```
template<typename It>  ( first,  last);
```
Seeds a linear_feedback_shift_engine with values from the range [first, last).
```
 ();
```
Returns the next value of the generator.

template<typename Iter>  ( first,  last);

Fills a range with random values

```
 ( z);
```
Advances the state of the generator by z.

`linear_feedback_shift_engine` friend functions

template<typename CharT, typename Traits> 
   
  ( os, 
              x);

Writes the textual representation of the generator to a std::ostream.

template<typename CharT, typename Traits> 
   
  ( is, 
              x);

Reads the textual representation of the generator from a std::istream.

```
 ( x, 
                 y);
```
Returns true if the two generators will produce identical sequences of outputs.
```
 ( lhs, 
                 rhs);
```
Returns true if the two generators will produce different sequences of outputs.
