In the c++11 headers for the random number generation (random.h), the

As I mentioned when we optimized a while ago the discard member
function for the statistically much more solid mersenne_twister
engine, most of the discard are still just trivial implementations of
the specs, that is rather well know. On the other hand, we didn't take
code from Boost for our implementation and I don't think we are
starting now. Thus, if you want to see progress on this specific
discard, I would recommend either contributing a patch, if the issue
is simple enough for you to handle, or filing an appropriate Bugzilla
entry with a description of the optimization, then somebody will
contribute an implementation.
Thanks!

Greetings,
Thank you for your concern about the random facility.
A link to a reference paper or two would help if you don't want to/can't
contribute a patch.
Thanks,
Ed
