Re: [Haskell-cafe] good choice for random number generator ?

Seems that `vector-random-0.2` is incompatible with new fusion implementation of `vector-0.11` Also due “recent” GHC being more strict about pragmas, build fails for all GHC >=7.2 Data/Vector/Random/Mersenne.hs:85:5: The INLINE pragma for default method `random' lacks an accompanying binding I edited bounds on Hackage to disallow invalid build-plans. - Oleg

I added vector-random to matrix.h.h.o build queue [1]:

Will check whether it have some problems, and report here & upstream

There's quite a few. Many are very old.

I would have like to use vector-random and got this :

Data/Vector/Random/Mersenne.hs:33:18: Could not find module ‘Data.Vector.Fusion.Stream’ It is a member of the hidden package ‘vector-0.10.12.3@vecto_1COyUuV1LrA1IjYnWfJnbs’. Perhaps you need to add ‘vector’ to the build-depends in your .cabal file. Use -v to see a list of the files searched for.

Data/Vector/Random/Mersenne.hs:35:18: Could not find module ‘Data.Vector.Fusion.Stream.Size’ It is a member of the hidden package ‘vector-0.10.12.3@vecto_1COyUuV1LrA1IjYnWfJnbs’. Perhaps you need to add ‘vector’ to the build-depends in your .cabal file. Use -v to see a list of the files searched for.

I wouldn't be opposed to fixing it, but I'm wondering at this point there isn't a better package to use instead.

I'm looking for both integer and floating point random numbers, uniform and gaussian.

gsl-random looks promising as does mwc-random.

any other suggestions ?

Thanks,
