Subject: Re: [Haskell-beginners] randmomR produces only even values
Message-ID: <[email protected]>

According to the package documentation for System.Random:
This implementation uses the Portable Combined Generator of L'Ecuyer
[System.Random] for 32-bit computers, transliterated by Lennart Augustsson.
The paper in question is given as:
Pierre L'Ecuyer, /Efficient and portable combined random number generators/,
Comm ACM, 31(6), Jun 1988, pp742-749
Does anybody have a copy of this paper?
The use of an incrementing list of integers to seed each generation is
definitely unusual, as Lyndon has pointed out, and is likely to be the root of
the observed behaviour. Having the paper in question would probably clarify
this.
