[Lemon-devel] Mersenne Twister in libstdc++

[Balazs Dezso]

Hi

I have known it, but from my /usr/include/c++/tr1 directory. As I know, it is 
the copy of the boost random package. The template parameters are quite nasty, 
however there is typedef for the most widely used mt19937 generator. But the 
interface (excluding the template parameters) is acceptable, but I think the 
separation of the random number generation and the conversion to a given 
distribution is not a good design decision. The most of the user want to use 
the most effective random number generator (mt19937) with some distribution 
mapping. I would be nervous, if I should make every time extra 
object(std::uniform_int) to get integer from a given range (the objective of 
the solution is obvious, the class have to be a generator).

Best, Balazs
