Academic Integrity

posted on Nov. 23, 2014, 9:40 p.m. 10

Update: The Hall of Shame is empty for November.

The DMOJ is a fairly new system, and in the last few months we've seen an unexpected number of new users. Thanks for that: it really makes the time we put into developing the site meaningful.

However, we've seen an unfortunate number of contestants using solutions other than their own. Removing a few comments and refactoring some variable names does not make some code you found online yours.

There are many people here on the DMOJ who spent hours honing their programming ability, and they are to be admired. Likewise, there are also those who have just been copying solutions to gain points. The latter is not only unjust to those who have been legitimately working their way up the rankings, but it also doesn't match what the DMOJ aims to be: a place where contest programmers can compare their ability to others and improve.

In an attempt to curb the number of cheating users, starting from this month we'll be hosting a Hall of Shame on the DMOJ home page, listing offending users that we hope will change their ways. Cheaters may at any time request to delete their copied submissions, but once listed on the Hall of Shame their submissions are permanent.

Since we wish to encourage everyone to play fairly, anyone can request to have cheating submissions deleted before 11/25 to avoid being added to the hall of shame. You can either leave a comment on this post (which will be deleted as soon as the deletion request is fulfilled) or send us an email to dmcioj -at- gmail.com. If you contact us before 11/25, the offenses will all be history. But if you don't, and continue cheating, you'll make the Hall of Shame. And if you really push it, we might end up suspending your account.

Please note that we encourage getting hints or ideas from external sources, and the Hall of Shame is not intended to stop this learning process, provided that you are the person who writes the final code to be submitted on the judge.

Please be nice and play by the rules. Thanks.
