Hi all,
We are happy to announce that PEG accounts and problems have been migrated to DMOJ, and can now be accessed.
Some usernames on PEG could not be assigned on DMOJ, as they were already in use. A _wcipeg suffix was added to the PEG username in these cases. You can check this list to see if this applies to you.
PEG accounts may be merged into existing DMOJ accounts (in the case you had an account on both DMOJ and PEG, and would like to merge them into one). To initiate this process, visit your profile page while logged in to your PEG account, and follow the instructions.
All PEG submissions were regraded on DMOJ judge hardware to keep rankings consistent. You may view a spreadsheet of aggregate rejudging results here. Submissions to a number of problems (mainly IOI) have not yet been assigned to migrated accounts, but will become available in the coming days.
Feel free to let us know of any questions you may have in the comments, in Slack, or by email.
