hi robert,
i hope you spent not much time in that!
please have a look here: http://www.rieselprime.org/FirstKTwin.htm.

all n upto 1130 are filled in there and with gaps upto 1400.

I think it is an interesting exercise because of the statistics of series like this. If you plot all the values then it increases gently and there is a nice curve bounding 95% of values, but the outer envelope of the rogue 5% seem to be increasing on a much steeper curve.

I have a hunch that you could look at really rather a large set of consecutive n's then you would be certain to find a twin prime over a relatively small k range, and that would be more efficient that the current k*2^333333+/-1 twin search, as 333333 might be just such a rogue!!

Statisticians could I think define such a range of manageable k and n to produce 99% probability of getting a twin. Whereas n=333333 - who knows!

I agree completely Robert. I suggested this to MooMoo, the TPS project leader, in an Email several weeks ago. I didn't hear anything back. I think they've already decided that they'll do a fixed-n search on n=500K after they find a twin for n=333333.

IMHO, searching a moderate-sized range of consecutive n over a much smaller range of k-values is more effecient in the long run due to the LLRing efficiency gained from the smaller k-values.

In theory, the chances are the same either way of accidently searching a bad range. The TPS way, it's a 'rogue' n-value. Using the way I did it, you'd have the same number of candidates with more n-values but less k-values but still the same chance of catching a rogue k/n range. But the reason why I think it is more efficient is because smaller k's LLR so much faster. Even though you lose sieving depth and efficiency, LLRing is a large percentage of any prime search so more effort should be given towards minimizing LLR time instead of sieve time.

To get to where I've searched so far on my effort, it's only taken a few months of 2 pretty slow older 2.66 Ghz P4's. If I put 10-12 faster CPU's on it, I could most likely search n=36K-100K faster than I did just getting to n=36K.

Take the first instance k for the first 1,000 n, shown in the table posted above on 21 February. Take all combinations of 15 consecutive n, and calulate the average of the k values chosen (=A), and the minimum k in the range. Multiply the minimum by 15 (=B), and compare to the average. A is smaller than B in 197 cases, but B is smaller than A in 788 cases. The broader the range so the number of cases that B

The value of n=1 should be k=2 instead of k=3, i.e.:
2*2^1-1=3 and 2*2^1+1=5.

Trivial result...the only twin prime for an even k, as shown on my web page.

 2008-03-07, 06:13 #39 robert44444uk     Jun 2003 Oxford, UK 111010100112 Posts Gary/ Karsten Decided to take a break from Very Prime Series and give a hand here. I have two machines (albeit with no CPU power) working on first instance (k) primes up to n=3000. Results of first instance primes to 1400 show a rather nice curve when plotting ln(k/n) against n. Best fit looks to be logarithmic as well. Would be interested to know if this might be a good way to target large twins. For example, if the extrapolation of the best fit to n=333333, gave A= ln(k/n)= 9, then the first twin would be, on average, at k=2.70103*10^9 then the test might look at n from 333333 to n 333433, say at A=8.999 to 9.001 or k=2.69833*10^9 to 2.70373*10^9. A 50 million k range, sieved to 1T would provide about 4,000 candidates for prime checking or 400,000 overall for a 100 k range. Mind you I am not sure A= 9 is right for n=333333. But maybe someone could extrapolate and work out the odds of finding a twin in the suggested k/n matrix. Also the plot of ln(ln(k/n)) looks as if it heading to a value of 2 with over 87% of values between 1.5 and 2 for n from 1 to 1383, and 92% from n=1 to 1383.
