[QUOTE=roger;137987]I figured out the A-value for the y=A*n^2, but I got a different answer than the 0.24 as suggested earlier.
[/QUOTE]

Roger, back after a lot of travelling. How did you calculate your values? The 0.24 conjecture is the median value over sets of 50 consecutive n values with almost all A in the range 50% -200% of the conjected 0.24

I took the trendline values of 0.3008*n^1.9545 to calculate the y-value for n=1.9545, then divided that y-value by the squared n-value (of k*2^n+-1).

Here's the steps I took in case I made an error:

y=0.3008*n[sup]1.9545[/sup]
y=A*n[sup]2[/sup]
A*n[sup]2[/sup] = 0.3008*n[sup]1.9545[/sup]
[0.3008*n[sup]1.9545[/sup]]/n[sup]2[/sup] = A

I used the last line of calculation on each n-value in k*2^n+-1, to come up with an A-value for each n-value in the curve A*n[sup]2[/sup].

The last data point (n=8000; the found twins) has an A-value of 0.19984.

I think I did something different than you though, because my values don't vary too much, they just follow an almost straight line (I posted the graph, and every thousand or so A-values a couple replies back).

OK, understood, but don't think valid, as the best fit is arbitrary.

Could the program we're using be modified slightly to do a large number of isolated k-values, for a large range of n-values?

I'm also trying to do the 100 primes by n=10,000 thing, and I think this would speed things up quite a bit for the higher n-values. The payam-base program could do the first 1000 or 2000 n-values, and spit out the k's that made it through. These would go to pfgw for n=1000 or 2000-5000, and the remaining would go through the modified cllr and .bat files we're using here. It would be a lot more efficient than pfgw-testing the ones payam-base spits out to n=5000, then sieving for each of those to n=10000.

Also, is there a way to get the .bat files to only output the primes that it's found? It would save me a lot of time as well :smile: I'm guessing it would be a modification of this line:

DO @echo %%j %%i >>all_twins.txt

Thanks!

8000<n<8825 is done :smile: which makes for 95% of the first 10000 n-values complete :yay:

I think I'll finish off the 9500<n<10000, then just work on individual n-values.

Update on individual n-value search:

updated the page with first twin-k with new data (from roger upto n=9500) and new images.

roger 2008-11-30 07:01

5 more n's to find twins for, then we're done to n=10,000!

I think this milestone deserves a :et_::paul::maybeso::banana::george:

Will post full excel document (2MB) once completed.
It includes a lowest twin graph (logarithmic); deviation from mean (min/max); jumping champions (68 so far); average twin k-value; A-value for curve=A*2^n (at n=10000 A=0.20206).

After this, I will work on some higher n-values (in the range of 50k-80k I think) and may help more in smaller chunks to further this search.

COMPLETION
