### Dataset Summary
> UQ is a collection of 500 popular unsolved questions from StackExchange sites covering Science, Technology, Culture & Recreation, Life & Arts, and Business.
## Dataset Structure
### Data Instances
An example looks as follows:
```json
{
'question_id': '5',
'site': 'crypto',
'title': 'Finding $x$ such that $g^x\\bmod p<p/k$?',
'body': "In a Schnorr group as used for DSA, of prime modulus $p$, prime order $q$, generator $g$ (with $p/g$ small), how can we efficiently exhibit an $x$ with $0<x<q$ such that $g^x\\bmod p<p/k$, for sizable $k$ but $k\\ll\\sqrt q$ ?
I see that for small $k$, it is enough to try incremental values of $x$ until finding an $x$ that fits, with expected cost $O(k)$ modular multiplications in $\\mathbb Z_p^*$. Is there better?
Assume $p$ is an $l$-bit prime; $q$ is an $n$-bit prime with $q$ dividing $p-1$; and $g=h^{(p-1)/q}$ for some (random?) $h$ in $\\mathbb Z_p^*$. For concrete values, assume $l\\approx1024$, $n\\approx160$, $k\\approx2^{64}$.
Update: I'm expecting the problem to be hard, and thus that the more difficult problem of exhibiting $x$ with $g^x\\bmod p$ in a range of width $p/k$ must be hard.\

'tags': ['discrete-logarithm', 'group-theory'],
'votes': 19,
'creation_date': datetime.datetime(2017, 6, 20, 8, 57, 11),
'comments': ['Can you please provide me with some real values of variables in question instead of me attempting with random values.', '@pintor: no, I have made no progress nor got more feedback than the above comments.', "@fgrieu, did you get any more updates on the problem? I'm also curious", "This seems to reduce to a discrete logarithm problem in the multi-target setting, with a potentially very high target number depending on $k$. For a $k\\approx \\sqrt{p}$ index calculus seems like the best choice. Once you have one solution, getting more is relatively fast. Unsure if there's something better.", '@SamuelNeves: yes; the only constraint on $g^x\\bmod p$ is that it is small (about $\\log_2(k)$-bit smaller than $p$ is).', 'Do you get to choose what the $g^x \\mod p$ value is?', '@puzzlepalace: thank you for finding a hole; plugged it.', 'Choose $x = 0$ ? Runs in $\\Theta(1)$ ;)'],
