I've been informed that the COLT PC this year is looking for more submissions for Open Problems which will appear at this year's conference. The deadline has been extended to May 11, more information is here (the extension is correct, despite the date the website currently states). Personally, I'm a fan of the open problems session -- I've coauthored 1,2,3 of them -- as it provides a venue for suggesting future research directions that does not require having a fully-baked result.
Please consider submitting something!
Call for open problems:
COLT 2011 will include an Open Problems session. A description of the problems posed will also appear on the conference web site (and in the electronic proceedings).
We encourage everyone to propose and present a clearly defined open research problem (or several closely related open problems), relevant to COLT. Authors should carefully prepare a brief writeup including a clear, self-contained description of the problem, their motivation for studying it, and the current state of this problem (including any known partial or conjectured solutions and relevant references). As last year, we encourage submissions of problems not conventionally in the scope of COLT, as long as there is a convincing reason to include it in the conference. You should be able to clearly express the problem in a 5-10 minute talk. A reward for solving an open problem is encouraged but not required.
If you would like to submit a problem, please email it to email@example.com by
March 27, 2011May 11, 2011. Submissions should be at most 2 pages long and be in the COLT format.
