Hi all! Sorry if this is an inappropriate use of meta.

I am trying to find a question that was asked within the last few months, which was about a hitting time for a certain random walk. I believe it was a random walk on the integers which was able to move by more than 1. The question was about the time to reach a certain value, and it was made complicated by the fact that the process might jump over the value without actually reaching it.

I searched every term I could think of, and browsed the last several months of questions tagged "probability", but I cannot find it. If anyone remembers the question more specifically and can point me to it, I'd appreciate it.

Note: It's also possible the question was on MathOverflow instead of here. I searched there as well without result.

  • $\begingroup$ Is there a result of your interest coming up in google.com/… ? This is by searching "hitting time random walk site:math.stackexchange.com" in google. Similarly, it can be searched in mathoverflow.com $\endgroup$

  • $\begingroup$ @Tim: Thanks, but no, I didn't see it there. I am not sure that the words "random walk" or "hitting time" were actually used in the question, I just remember that this was the essence. $\endgroup$ May 9, 2011 at 20:49

  • $\begingroup$ @AsafKaragila Well, the Ravens did win the Superbowl XLVII, and they just visited Obama for that reason, but ... yeah, I don't get the tag either. $\endgroup$ Jun 6, 2013 at 4:05

    $\begingroup$ @AsafKaragila: Sorry about that, there was a suggestion in another question that the new "edit tags" button existed so that 10K users could retag without bumping. I couldn't find an official word so I thought I would test. Apparently it still gets bumped :( Sorry for the noise. $\endgroup$ Jun 6, 2013 at 12:22

After some more fruitful searching, I think I must have been thinking of A probability question. I thought it was further back than that. My memory must be going...

    $\begingroup$ I can't blame you, that title is awfully nondescript. $\endgroup$ May 10, 2011 at 13:08

    $\begingroup$ Why not edit the title to contain the words you searched for? $\endgroup$
