Randomness is an observed entity[edit]

The article starts out with: "A random number generator (RNG) is a computational or physical device designed to generate a sequence of numbers or symbols that lack any pattern, i.e. appear random." But it should be the other way around: If an Observer find that a sequence lack any pattern, it appears random to him. Different observers may rate the same sequence differently. The randomness is not in the sequence.

Poor example MWC1616 should be replaced[edit] claims that this article uses the poor example MWC1616. It would be nice if someone more qualified would check the link and article, and possibly insert a more appropriate example of a PRNG.

If the current example for chosen simplicity and briefness rather than quality, it might be reasonable to instead pick something even simpler like DJB2, which I believe is a lot easier to explain. If instead quality is an important factor, MWC1616 seems to be a poor choice even in the refined variant, according to the link. --mafutrct (talk) 15:12, 21 November 2015 (UTC)

@Mafutrct: the stock standard PRNG algorithm is (as the linked article points out) the Mersenne Twister, but if you want something with a very short pseudocode and comparable quality, xorshift is just a few lines. Chrome will apparently use xorshitf128+ to replace MWC1616. --Tgr (talk) 23:41, 31 December 2015 (UTC)

Just as an update: MWC has since been removed from the article. Sadly without a replacement. --mafutrct (talk) 13:56, 18 May 2016 (UTC)


I've always been led to believe that the digits of pi are truly random. Is this so? If so, worth a mention, I would think, since pi provides . . . how many now, 1 or 2 quadrillion random digits (I don't know what the current total number of known digits of pi is right now)? (Double that since presumably a random sequence is just as random when taken backwards(?)) DoctorFun1970 (talk) 15:03, 1 September 2016 (UTC)

The problem would be making a random number generator to provide a choice for which number in the digits of pi to use. WikipediaUserCalledChris (talk) 20:28, 23 January 2017 (UTC)

Random number generation input through analogue computer filtering as an attractor which shapes the range of the output*[edit]

write about it please
