Unless George/Scott set some legal mumbo jumbo that ties into use of the program/source/services, they're simply not "entitled" to any prize money. I'm forced to agree with Aaron, aparently at gunpoint :-) (and I said this a while ago, BTW). Even if they (George and Scott) did this, then there

[Not in reply to any specific message - no names, no pack drill] Hey, guys, surely we don't want a war over this? Here are a few relevant points: 1. GIMPS/PrimeNet as a whole constitutes a "team" in so far as we (usually) co-operate loosely with each other in order not to waste time and

Hi all, You may have noticed that the web pages at mersenne.org haven't been updated recently. The reason is I've "lost" FTP access to update the pages. So, after several years at lushen.com, I'll be moving the web pages to entropia.com in the coming weeks. Be prepared for a few

Mersenne: Proth Vs. Mersenne (Grudge match of the century)

1999-07-25 Thread STL137
Is that true? I thought that a LL test of a Mersenne was faster. Everything I've ever heard says that LL tests are faster than Proth, and in fact the quickest test for primality versus other types of numbers. Hm. S.T.L. _

Re: Mersenne: Evil, evil prize thread

1999-07-25 Thread Lucas Wiman
At present we find approx. 1% of the LL test results submitted are incorrect. That figure seems a tad high. After double-checking, there would be a 0.01% chance that BOTH tests had failed, which seems very high to me. Well, the likelyhood that a failure occurs may be 1%, but the likelyhood that

Proth's Test for n = k*2^m+1 says that there exists a such that a^(n-1)/2 + 1 is divisible by n. The other factor in evaluating this is that, in Proth's Test, a has got to be an odd prime - if you pick the wrong prime, you're wasting time, though fortunately this can usually be detected very

That bit is virtually free of charge. Any quadratic non-residue will do just fine. But you don't easily know if a number is a QNR, do you? Suppose the number you're testing is N. If we assume N is prime, then quadratic reciprocity could be used to determine whether your base a is a QNR. So
