Relationship Between numbers: math expert needed

[salsa086]

Can anyone tell me what the relationship is between these two numbers:

The the original number was: 350314010280171

a process was run on it and the output was: 84341543

Any ideas? How would I go about analyzing these numbers? Anyone have a program they've written that runs some common relational analysis sequences?

Insufficient information here. There are an infinite number of processes that could be run on the first number to change it into the second - for example, I could:

1. Subtract 350313925938628 from the first number - voila, I have the second.
2. Subtract 350313925938629 from the first number, then add 1 - voila, I have the second.
3. Subtract 350313925938630 from the first number, then add 2 - voila, I have the second.
4. and so on and so forth.

You can throw in division, multiplication, square roots, etc.

Now, if you had several sets of data (X1->Y1, X2->Y2, X3->Y3), one might be able to start whittling things down...

thats what I had assumed... I'll try and find more sets of examples

 

[salsa086]

350314010280171 ----- 84341543

If I add the 1st and 2nd digits, I get 8
If I add the 3rd, 4th, and 5th, I get 4
If I subtract the 6th from the 5th, I get 3

Not sure if this is a pattern or not...

Ok I now have two example sets:

1st:

350314010280171 ----------------> 84341543




2nd:


350314001287235 ----------------> 67525619


The same process was run on both, any suggestions for going about discovering the process?

FWIW, this potentially could be unsolvable regardless of your sample size - things like public key encryption depend on you NOT being able to solve this problem for the process they use.

if you could tell us the background to the problem it might help us. i.e. how are you getting these numbers.

You'll need more samples for a start.

there's infinitely many relations defined as functions between any two given numbers.

would u like someone to attempt an enumeration of all of them?

I would if you don't mind.

a, 0 , 1 , 2 , ...

f0(a), f0(0), f0(1) ,f0(2) , ...

f1(a), f1(0) , f1(1) , f1(2), ...

f2(a), f2(0) , f2(1), f2(2), ...

...

damn, it turns out to be nondenumerable...
