Possible issues with random number generators for calculator apps

From there I checked the rng of the family "linear congruent" and they do have a fixed pattern (in parallel planes). Their usage should be fine for small, non crucial, applications.

Namir side questions for you : while I believe that whatever personal exploration is important for understanding a topic, your "new" algorithms are really new or are labeled as "new" as in "I searched for a while and I did not find anything similar?" (this would be still a problem, how does one know if he has searched enough? Is one searching day enough? Ten? One thousand?)

The test for randomness requires fast machines and software. I use Matlab for speed, because I usually generate a few billion random number in testing a set of algorithms.

I post new algorithms that I develop myself. I have been looking at root-seeking algorithms sine the mid 70s, so I have a good idea of what's out there. I did post recently a survey of new modifications for Newton's method created by others. I usually don't search for similar algorithms. Now that you have mentioned that subject, I officially appoint you as algorithm searcher!! I will stick of thinking of new algorithms :-)
