What problem does this idea solve that isn't solved by an existing blockchain? Why is this better, from a crypto standpoint?

How would you make the numbers to be factored of any interest...

Reserving 13_2_927m1.
I've decided to do some 16f sieving from Q=20-25M locally, so I may as well solve the matrix when ready.

You really ought to consider how many [expected] trials it would take to find one counterexample. I mean, Charybdis spelled it out for you, but you seem to have ignored him. A one in 10^50 chance per...

First one done (quoted number for clarity), 1000@65e7 and 800@12e8.
Starting second one now.
Haven't finished building the new desktop yet, which is why this is taking 3x as long as I expected.

Was gonna say... yield of 1 is never ever a good idea. C169 is right on the edge of 15e-small.

If I've got the scaling of poly score vs sieve time, looks like 88 is quicker.

Not really; you'll have a slightly higher duplicate rate, meaning you may need an extra 1-3M raw relations to get the matrix size you expect. Sieve time will barely change.

As long as the input number is close, comparing E-score is pretty accurate (as I did in my previous post). It shouldn't matter whether you go with 163 or 165 or 166 next time for the mfb 89 trial....

Looks like a 6% better scoring poly than the last test, but only 4% lower sieve time.
Nearly a wash, but I=14 is also lower memory while being not-slower.

I don't understand your question- 241 *is* the difficulty of this poly. It's just that quartics are much much harder than 5th or 6th degree polys at that size. "241" isn't a rating of how long the...

Excellent point- we want the ratio of qmin to qmax to be something between 6 and 8. I suspect your C164 with I=14 ran Q roughly 10-60M; since A=28 should yield 40% better, a Q-range of 7-43M might be...

I think / hope each change should be independent- that is, you have determined strat 2 is faster (really, Charybdis determined this over a year ago), now it's the default. Next, try A = 28; once we...

There is no such thing as "yield too high". Average yield of 3 to 4 is a good thing; I've run jobs with yields of 6+ with pleasant results many a time, and on small jobs I've seen yields of 10+.

Poly score 2.5% worse, but sieve time roughly 5% better. Nice!

The next settings to test are A=28 and mfb1 = 89. A=28 is more important a test (mfb should not change sieve time very much).
