How about using a [static inline?] function that itself holds a static
PRNG object that you simply re-seed with each call?
Something like this:
static inline RandomNumberGenerator& PSRNG (void) {
static AutoSeededRandomPool rng;
rng.Reseed ();
return rng;
}
Then call this function (PSRNG ()) from your loop?
Would that help? Its not creating/destroying a new object all the time
just returning a reference to an already instantiated object (re-
seeded).
