A message about copying code

After noticing a particular submission from someone (you know who you are), I feel that this message needs to be heard, particularly by Churchill PEG members. The admins of this site are really not oblivioua. Looking at a submission, we can easily tell whether someone earned the points for a problem legitimately. We realize for many problems on the PEG Judge, solution descriptions or even solution programs can be found online. There is nothing we can do to stop you from giving yourself a hint by, for instance, reading a few sentences of a solution PDF, and then implementing the program on your own.

The problem arises when you copy somebody else's program, change some variables, add a few sporadic comments, and submit it in one go for a perfect score. This is blatantly cheating. We don't really care about public users doing this since it's their own programming skills that they're trying to improve. There are certainly no merits to copy-pasting code all day long to gain imaginary points on a website. However, among rising programmers in PEG who are consistently competing with each other (for ranks, rewards, trips, etc.), points DO mean something. Thus, we must be particularly strict with enforcement of this policy.

It is very unfortunate that not only did you try to illegitimately obtain 50 points through 1 problem while your peers are working so hard to even earn 30 on several, you decided to brag about solving it on your own in the comments. It is even more unfortunate that you chose to do this right after we all discussed proper use of the PEG Judge last Wednesday. In the past, our leaders/teachers would not have hesitated to kick out students for such offenses. For this one time, the score for your submission has been set to zero. It's never happened before (and we don't plan for it to), but if similar events persist, we just might start seeing negative scores for submissions. Let's learn to be grateful that this tool is available for us.

TL;DR - Just get points legitimately; we're reaching a limit on warnings.

Submissions and comments from today (Oct 28) were lost due to an issue with the database.
We apologize for the inconvenience. Please remember to always back up your programs locally in case of similar events in the future.

Sort by "Date Added" now works sensibly

The Judge used to not actually keep timestamps on when problems were added, so I had most of them guessed. (For problems in contests, I set it to an hour before the contest began, and for most other problems, I set it to a minute before the earliest submission to the problem.)

Problems added from now on will appear in the correct order. Sorry for the inconvenience.

COCI 2009-2010

The test data for all the COCI problems from 2009-2010 has been uploaded to the PEG Judge server.
Edit: All COCI problems from 2009-2010 not requiring custom judges have been added.

Ratings reset

I dropped all the ratings from old "contests" that were really just PEG exercises or imported contests. Ratings were recalculated based on the two public contests held on the Judge so far (one mock DWITE and one mock CCC). For most previously rated users this probably means you're no longer rated; in other cases your rating may have changed.

I hope to hold more contests on the Judge in the future.

Improved code editor

Thanks to Robin Cheng (javic), the textarea on the submit page now supports tabs (if you have scripts enabled).

C++11 support

by bbi5291 on Jun 08, 2013 - 12:19:28 am UTC
  • (4/0)
gcc 4.8.1, released today, is the first major C++ compiler to support all C++11 language features. The PEG Judge now supports C++11 using gcc 4.8.1. To submit in C++11, just select the option at the bottom of the dropdown. C++11 has been enabled for all problems that support C++ (that is, all of them). Submissions tagged "C++" will continue to use the old compiler, gcc 4.1.3.
