An efficient random generator monad, based on the Mersenne Twister http://code.haskell.org/~dons/code/monad-mersenne-random

Latest on Hackage:0.1

This package is not currently in any snapshots. If you're interested in using it, we recommend adding it to Stackage Nightly. Doing so will make builds more reliable, and allow stackage.org to host generated Haddocks.

Often we need an efficient way to generate high quality pseudo-random numbers in Haskell. We have good generators themselves (for example, the mersenne-random-pure64 package), however, users are often tempted to store the generator in a lazy state monad. This causes performance problems.

This package provides an optimized Rand monad for monadic generation of random numbers from a state, with close attention to performance. You may have results an order of magnitude or more better than using Control.Monad.State to store your generator.
