Random Numbers?

Hi,

Anyone know what the underlying RNG in LW is?

If not a Mersenne Twister, does anyone know how to properly, and randomly, seed the MT19937 RNG? (e.g., from GSL?)

I can't answer your question but you might be interested in the cl-variates project

(It's maintained but not under active development).
