mersenne_twister_engine
is a random number engine based on Mersenne Twister algorithm. It produces high quality unsigned integer random numbers.
The following typedefs define the random number engine with two commonly used parameter sets:

[edit] Member types
Member type  Definition 
result_type

The integral type generated by the engine. Results are undefined if this is not an unsigned integral type. 
[edit] Member functions
Construction and Seeding  
constructs the engine (public member function)  
sets the current state of the engine (public member function)  
Generation  
advances the engine's state and returns the generated value (public member function)  
advances the engine's state by a specified amount (public member function)  
Characteristics  
[static] 
gets the smallest possible value in the output range (public static member function) 
[static] 
gets the largest possible value in the output range (public static member function) 
[edit] Nonmember functions
compares the internal states of two pseudorandom number engines (function)  
performs stream input and output on pseudorandom number engine (function)
