I just follow the experts that know about these things. I've never had time to study the details of it. If I ever need a definition then I just use the typical search engines. Razz

aw, c'mon revoLution, stick your neck out, pleeeeease Laughing Are you now saying the concept of a (good) prn is so complex that you can't even offer a suggestion? Razz

revo1ution: I can't offer a suggestion. I know it has something to do with the number of dimensions because I occasionally see that quoted in the documentation of RNGs that are known to be good.

Dimensionality is an easy way to move beyond computatablity.

In general, when talking about PRN's, the quality is based on the environment of utility. Most PRNG's could be specifically targeted to reduce the percieved randomness. Of course, there are generally applicable PRNG's - usually a combination of mutiple simplier PRNG's (to increase dimensionality).

This is most unlike you revoLution, you are usually so knowledgeable Wink And not afraid to offer your opinions, like here for example Razz Maybe you are truly thinking about my question now Question

Nope. Sorry but I don't have time to teach myself about all the details so that I can explain it to you. For the most part I already know the relative positions of RNGs compared to each other, hence I can confidently say that LCGs are not good quality. But when you ask for a complete description of exactly how to measure the quality then I will just refer you to my website. Wink

Anyone else recognize how it's always revolution that first responds to revo1ution?

Hm...it doesn't appear to be random. Very Happy

Ok, I admit it, I'm arguing with myself!
Trouble is, I'm losing those arguments Embarassed
But, about flattery, I couldn't possibly say that

Humans have a great ability to see patterns where none exists. While some may think that something is non-random because they see a "pattern", that is mostly just the pattern recognition algorithms being rather too eager to strut their stuff. Especially where the number of samples is very small.

They say that imitation is the highest form of flattery.

Would you also qualify the ability to see multiple simultaneous perspectives as strictly pattern recognition? Differentiation seems to require development of another nature. Wink

This page ...

http://www.sciencenews.org/view/generic/id/340530/title/Physicists_go_totally_random

... appears to be describing a way to combine two not-random (i.e. pseudo-random) sequences to create a random sequence. It is lacking in any details though (as seems to be usual for the typical "news" sites). Does anyone here know what is being suggested?

I had always been taught that it was not possible to get real-randomness from any non-random sources, no matter how many were combined. Perhaps my teachers were mistaken on that point?
