[math] Improving tests and performance of RandomGenerator implementations

2011-07-31 Thread Phil Steitz
In my own applications, I noticed what appears to be poor performance in the nextInt(int) method of the Mersenne twister, which I was using to *improve* speed. I think that for small n, the default implementation in BistreamGenerator may be running too many iterations. I am still figuring out how
