Does CodeChef check plagiarism?
All submissions are filtered through MOSS (a plagiarism checker tool), that throws up pairs of submissions with similar code percentage. Then, we manually look at those to identify the right parameters to find similar-looking solutions.
How can plagiarism be removed from source code?

- Learn to comment on your code.
What is Moss plagiarism?
Moss (for a Measure Of Software Similarity) is an automatic system for determining the similarity of programs. To date, the main application of Moss has been in detecting plagiarism in programming classes. Since its development in 1994, Moss has been very effective in this role.
How can we prevent Moss plagiarism?
If you can change all the variable names, the structure of the code, modify functions, change if statements to switch statements, and ultimately change the coding style, you will get away with cheating the MOSS detection system (every time).
How is rating done on CodeChef?
A very basic idea of how the ELO system works is this: Whenever you participate in a contest, you compete in a duel with all other participating players. Based on your existing rating and the other participating players’ rating, your probability of winning against each of them is calculated.
How does Hackerrank detect plagiarism?
We use two algorithms for detecting plagiarism: Moss (Measure of Software Similarity) and String comparison. We find similarity in the code using both String comparison and Moss and then use a minimum of both for smaller lines of code.
What is default rating in CodeChef?
Each player in his first contest would have an initial rating of 1500 and initial volatility of 125. The rating changes are capped with a max rating change computed as . The volatility value is moderated to lie in the range (75, 200).
How good is Moss at detecting plagiarism?
Moss is not a system for completely automatically detecting plagiarism. Plagiarism is a statement that someone copied code deliberately without attribution, and while Moss automatically detects program similarity, it has no way of knowing why codes are similar. But the scores are certainly not a proof of plagiarism.
Does codecodechef plagiarise?
CodeChef is a product of this love, and the collective sentiment of the community has made the platform what it is today. Plagiarism is an unfortunate by-product of almost any online contest, and ours has been no exception. To plagiarise in a platform that is built to strengthen one’s skill in programming is just counterproductive in the long run.
What are the different divisions of CodeChef?
Based on your CodeChef overall rating, you will now fall in either Division 1 or Division 2 or Division 3. All CodeChef contests (Long Challenges, Cook-Offs, LunchTimes and Starters) will now have three parallel contests, one for Division 1, one for Division 2, and another for Division 3. You can learn more about this system here.
What is the maximum rating for plagiarism charges?
For users whose ratings have been dropped to zero following plagiarism charges, we are increasing the rating by a maximum of 800. We have also ensured that user is penalized by at least of a rating difference of 750.
Should you plagiarise in a programming platform?
To plagiarise in a platform that is built to strengthen one’s skill in programming is just counterproductive in the long run. We’ve had plagiarisers since almost the beginning, but we started taking measures against them only after a few years.
