 | Well I finally worked through a lot of the mathematics with my surrogate factoring idea to the point of getting a good handle on exactly what it is and how it works--it's a super sieve method.
To understand why it's a sieve, consider that I rely on finding rational x, y and z, such that
yx^2 + Ax - j^2 = T
and
yz^2 + Ax - j^2 = 0
where A, j, and T are integers, and j^2 + T = M^2, which is the target integer I'm trying to factor.
What I did was ask a basic question, what rational values for y can fit?
If you know much mathematics you should know that either quadratic can be solved by an infinite number of rational y's, and in fact, both can also be solved by an infinite number, BUT my work shows a unique subset of that infinity, which is where things get started.
All other rational y's that fit such that all the conditions are held are just trivial multiples of the base set, and provably, if any x exists such its numerator has only one prime factor of M, then that subset of y's will give it.
However, it turns out that the probability as M gets larger that one of the rationals x's will reveal a prime factor of M is roughly 50%, which is a fascinating result that has to do with quadratic residues.
So why is it a super sieve, why is it a sieve at all and how does it relate to quantum methods for factoring?
Well, by putting the two requirements that I do, I make a situation where the mathematics loops through *combinations* of factors of j and T, to try and find if ANY of those combinations can be matched with integers from the full set of integers--yup, it tests out of infinity checking against ALL integers--to see if x can have a non-trivial factor of M.
Whether it can or not depends on quadratic residues.
Some of you may have heard of quantum methods for factoring where somehow simultaneously a huge number of possible factors can be checked, to factor a number, and that was actually demonstrated with a factorization of 15.
If you know your math history, you may know that mechanical means of factoring have been around for some time, but we don't rely on the mechanical means as it was more important to abstract out the underlying mathematical reasons.
I have abstracted out *how* quantum methods--basically mechanical factoring--actually must work mathematically.
You see, there had to be a mathematical basis, which would lead to a relatively simple way to factor.
Now to many of you I'm just some "crank" who is babbling, but that's because you lack enough sophisticated mathematical knowledge to understand how it works, or even to quite get what I'm saying.
That's ok. I can simply demonstrate.
Now it's basically an accident that this information is out on Usenet, as while I do rely on Usenet to talk out ideas, when I had a breakthrough with the factoring I went to mathematicians by email first, and even sent a copy of my paper to Shor.
After I got little back from them I contacted the US Government, multiple times, and verified receipt and was told my work would be looked over, but basically I got no response, and clearly they didn't take me seriously.
When I wrote my program, and was excited to see it factor, and then disappointed to see it fail, I began to think maybe I'd just screwed up, and hitting a wall, I put my work in the public domain.
Now there's no way to pull it back, so I'm pushing forward.
The original algorithm in my program, will, my current analysis shows, factor about 50% of the time, which is astounding.
I get a sense that some of you don't get it, so let's say you take some RSA challenge number, and calculate j and T, and factor them, and then run them through the algorithm.
My research indicates you have a 50% chance of factoring the number.
That's NOW with what I've put out there.
Some of you may notice that people who reply to me, chatter a lot, say a lot of negatives, but don't refute mathematically.
Think about it. If there are people who notice a new factoring algorithm talked about, and get curious enough to check it out notice that it factors 50% of the time, do you think they'll talk to any of you?
I'm talking to you because there are multiple screw-ups and missed catches at many levels, and it probably will go down in history as one of the biggest boondoggles by intelligence services...ever.
Even if someone has already broken the RSA challenge numbers and sent answer to RSA, what makes you think you'd know by now even if that happened?
You people are out of the loops. As soon as I get a little further, now that I see myself having broken through, I won't tell you a damn thing either.

 | You never explained why you think your foolish factoring algorithm executes in polynomial time. You have shown some crap code that you say works half of the time, and everyone else notes is horridly slow. We would be impressed, in spite of all your embarrassments, if you could at least make an argument that shows it is scales polynomial time, or at least sub-exponential time. Are you going to try to do that? If not, nobody cares what you have to say...

Wouldn't trial and error division find the factors 100% of the time? Now it might take a while (maybe longer than the universe takes to reach heat-death) but the question is whether your algorithm would be faster or not.

My algorithm is in polynomaial time.
It is significantly faster than what you're suggesting.
I did one test calculation of the number of combinations and found that a number made up by multiplying the first 1,000 primes together would give only around 100 million combinations.
That is, with a number that huge, my algorithm would probably loop through all the combinations on a decent pc in a couple of hours.
In comparison, it could factor an RSA type number, if the theory is correct, and all the implementation details can be worked out, in seconds.
Make no mistake, we can talk here as if it's nothing, but if the basic theory is right, then someone else may already be successfully breaking Internet encryption as we speak, with some fancy program or programs on a distributed system that can factor VERY large numbers in a few seconds, based off the math.
If my research holds up, and I think it will, then the basic algorithm itself, which is already out there, will factor an RSA type number 50% of the time, with maybe a few million combinations to iterate through for any given j that you try.
That's why this work should be taken seriously.
You can talk about it, or downplay it or whatever, but if it's correct and someone less silly than you people pays attention, they can start walking through Internet security IMMEDIATELY as in right now, not later, not in a few months, but RIGHT NOW.

Now wait a second. For the last few days (weeks?) you've been abusing people who've been pointing out that it didn't work. You've been making claims about how it was easy to prove that it works - then there was this claim that it was easy to prove that it worked 50% of the time, using quadratic residues...
How could you make all those claims _before_ you finally thought out exactly how it worked?
Guffaw.

Huh. I would have thought it was because almost everything you say turns out to be wrong.
What's truly remarkable is the fact that when someone says you're wrong they're lying, but then when you finally realize you _were_ wrong that doesn't seem to change the fact that the people who said you were wrong were lying. _That's_ the part about what you're saying that _I_ don't quite get...

Conceivably, yes, if I used some other program to factor T, since my current program just would in all likelihood fail to fully factor it, as I call it recursively to do all the factorizations, breaking down a number until it gets to something smaller than 200, at which point it uses a table of primes!
Remember my method is *surrogate* factoring, which means you have to factor something!!!
To factor an RSA challenge number I'd need a full factorization of some number off of it. Now T = M^2 - j^2, where M is the target number, and j is a number you get to pick.
My analysis is that if you do that with my method there is a significant chance that you will factor M, if you use a full decomposition of T, and all combinations of its factors.
Now I know that you people don't believe me, which is actually good, as it just make it kind of funny, you know?
Like, if you believed me, maybe one of you might do it, but you won't because you don't, until someone of greater intellectual ability comes along, or I do it myself.
What I'm doing is getting a handle on the theory so that I don't waste time searching for a solution, like having to experiment with different j's to get one that works, without knowing exactly why it works.
Now someone else who only cares about getting the solution might not be so particular.
I'm about finesse.
You people talk a lot so I'm not worried about you. I can freely talk about this research without concern that any of you will do anything, but talk.
I have years of experience dealing with you, from which I can tell what you will and will not do.

For what it's worth, I cooked up a couple of ~64-bit primes (was a 104-bit product, I forgot to set the uppermost bits). They weren't specially chosen or even well-generated. I just used the rand() function to generate a binary string. Their product was 17417537469613251264524569748998981537. "factor" from: http://www.asahi-net.or.jp/~KC2H-MSM/cn/ factored it in 33.26 seconds (1128714656609730623 * 15431302648208293919). After a bit of trial and error, it turned out that it could factor the product squared minus 16 in 3.26 seconds: 303370611505381579716912725262028356146608169452120680027239449463266882353 = 3* 3 * 71 * 307 * 2673397 * 84828952219129 * 8533686513259849 * 799079573776815674841701598797953
How do you get the original primes from the above factorisation? Or does j have to be specially chosen?

From what I can gather, it's supposed to go something like: b_i = factors of j^2 ( = 16 in this case) f_i = factors of T (product squared minus j^2)
b_1 = product of some subset of b_i b_2 = -j^2 / b1 f_1 = product of some subset of f_i f_2 = T / f_1
A = some integer (not sure how to calculate this)
Then a possible factor is: (b_1 f_2 + b_2 f_1 + 2 j^2) / A
Since I'm not sure how to calculate A, I just calculated each possibility mod each of the original primes to see if it was zero. No such combination occured (except for the trivial cases b_1 = f_1 = 1 or the prime to be tested was zero).
Is my interpretation correct?

That's where you often get off track, failing to engage your full abilities. What you want instead is a method that will factor M given a factorization of T = M+j, where j is a number you get to pick. For example, pick j=0, and then your algorithm will run in linear time. Picking j=0 in T=M^2-j^2 is good too, but then you're left with tedious work to weed out the repeated factors. Set your goal higher.

Damm. I was going to suggest deriving a factorization of M from a factorization of 2*M, but your idea is much simpler and more elegant.
Oh well, not the first time something like this has happened - I guess we math guys should leave the actual programming to the pros.

Indeed, and yours is just the special case of picking j=M (I know James realizes that, I'm just pointing it out for your benefit). What he may not have realized yet is that his method is just a special case of picking j = M^2 - j^2 - M.
I wouldn't call it my idea, though -- it's almost certain I wouldn't have thought of it without JSH pushing in this direction. Since I'm too stupid to make it work anyway, James should get all the credit.
Right now he's got this niggling detail where, to factor M in polynomial time, he at least has to assume that factoring integers with twice as many digits is cheap. Some posters are making a big deal out of that, as if it were a fundamental problem. Really! It would be easier to prove that M can be factored in polynomial time if he got to assume instead that factoring M+0 takes negligible time. Even the chowderheads on sci.math could understand that proof. Heck, even I can write a linear-time Python program for it:
def factor(M): j = 0 factors = factorize(M+j) # returns list of factors in negligible time print [hex(p) for p in factors]
The only subtle part is using hex() to display the factors (Python's hex(n) takes time linear in the number of bits in n; converting to decimal instead would inject a quadratic-time component).

Ya, you're way out of your depth here again. I am too. We should charge admission for visiting this end of the pool.

I'm not sure why that's astounding. There are lots of algorithms that factor numbers 100% of the time.

Great, so try it on 7 RSA challenge numbers. You should have a probability of 127/128 of factoring at least one of them.
But this is useful only if your algorithm can factor in polynomial time.

Polynomial in what? You don't even know what that means. You are just spurting buzzwords that you feel sound as impressive as what you think you are doing.

The concept of "proof" is a foreign one to JSH.

I must have missed your proof that your algorithm works in polynomial time. Obviously this is the crucial point. Could you repeat that argument, or point me to a reference?

Then, factor an RSA challenge. If it works 50% of the time, try it on a bunch of challenge numbers, and give us the factors of at least one. If you had such an algorithm, it would be incredibly easy to prove it by doing the above.

What degree polynomial?

And your posting history reveals "what you will and will not do." Namely, you *will* launch a self-aggrandizing, irrelevant diatribe and you *will not* meet the challenge the previous poster laid down.

I'd be impressed as hell if he can factor something like 50% of the open RSA challenge problems.
Then again maybe I'm more easily impressed than most, having been among the 25% of the world's pure mathematicians that he had fired from their jobs. :wink:
