[computer-go] C++ random numbers

[David G Doshay]

If you really want a decent generator, look in Knuth.
I do MC in physics, where the quality of the generator
is paramount, and you can get bad results with bad
generators. I have had good results with the "shuffle"
technique, which requires 2 random generations to
get one random number.

There is also a good discussion in the Numerical
Recipes books, with code for several generators,
including a very good one that requires 3 steps:
high order, low order, and shuffle.

Cheers,
David
