About
What this is
The Problem Board is a board of open research problems for the Georgia Institute of Technology research community. Members post problems they are interested in and have not solved yet, claim solutions to problems others have posted, and discuss both.
Why
Open problems circulate by luck. Someone mentions one over coffee, or in the last slide of a talk, and whether it reaches the person who could solve it is chance. Inside one university that is a fixable problem: the people are already in the same place and simply cannot see each other’s open questions. This is a place to put them where the relevant stranger two buildings or two floors away might read one.
Who does what
Anyone who has signed up can post a problem. Anyone who has signed up can claim a solution. The same person routinely does both, and nothing here treats those as different kinds of membership or maps them onto how far along someone is. A graduate student poses problems; a professor claims solutions; both happen the other way round just as often.
The admin role is a moderation duty — reviewing claims, deciding what gets published, and removing anyone who should not be here. Admitting people is not on that list: a gatech.edu address admits you by itself, with nobody in the middle. The role is not a rank, and it says nothing about whose mathematics is better.
Working with AI
Work done with AI assistance is welcome here, and it is disclosed. Every problem and every claim carries an AI-assisted or AI-authored marker when its author says so, with a note naming the model and what it did. Nothing on this site ranks, sorts, or filters on that field — it is a disclosure, not a demerit, and treating it as one would only teach people to stop disclosing.
The member who posts is accountable for correctness regardless of what helped them write it. That is the whole of the rule. It is worth adding that the collection a few problems here were adapted from is itself human-directed AI work, and says so on the face of every document — as do the problems adapted from it.
Membership
Membership needs a gatech.edu address and nothing else. There are no passwords and no queue: you ask for a link, it arrives by email, and clicking it makes you a member.
The domain check proves one thing — that you control a Georgia Institute of Technology mailbox today. It does not prove current enrolment or employment, and an alum keeps access until an admin revokes it. That is the trade this board makes knowingly: the email check is the gate, and a person still decides who leaves, not who arrives.
Join if you have an address.
Visibility and licensing
Problems start visible to members only. A submitter can request publication, and an admin decides. Publishing makes a problem readable by anyone on the internet.
Publishing licenses the problem record — statement, significance, known results, references — under CC BY 4.0. Solution claims and discussion posts are never CC-licensed. Their authors keep them; this site holds only the licence it needs to display them.
Claims that are under review, and claims that have been accepted, are visible to whoever can read the problem. Claims that are pending or were not accepted are visible only to the person who filed them and to admins. That is deliberate: an attempt that does not work out should cost nothing, or nobody will make a second one.
Where the imported problems came from
A few problems here were not posed by anyone on this board. They were adapted from Statistics for AI Safety, an openly-licensed collection of open research problems, and you can read the original of any of them there. Each one says so on its own page: it reads “Sourced from the work of” rather than “Posed by”, and carries a CC BY 4.0 notice.
The mathematics is unchanged. What the adaptation changed is presentation: the original prose was split into a setup and a question, so the question could stand on its own; notation was rewritten so it renders here; and pointers to neighbouring problems in that collection were dropped, since those problems are not on this board.
Who runs this
The Problem Board is run from within the Georgia Institute of Technology research community, by one person alongside other work.
Write to huo@gatech.edu if a sign-in link might not be genuine, or if you have lost access to an account. Those two are always worth an interruption, and checking a link before you click it is never an overreaction.
Everything else about a problem — what it means, whether it is still open, how you might approach it — belongs in that problem’s discussion rather than in a private inbox. The people who can answer are the ones reading there, and an answer posted there reaches everyone who had the same question.
This site is independent and is not operated by the university.
