Re: [Haskell-cafe] Optimization flag changing result of code execution

I've tried to run you program and I've got approximately same results regardless of optimization level. Which versions of GHC, mwc-random, vector and primitive do you use?

By approximate do you mean you are getting Monte Carlo noise or Floating Point noise? If the latter then that's reasonable; if the former then that's worrying. Dominic.
