After the completion of qualification contest, a selective check for cheating in participants’ solutions was conducted. Several instances of non-independent completion of the tasks were identified.

Solutions are considered copied (borrowed) if the jury believes that code is significantly similar, even though the code may not match exactly. Typically, programs are modified to disguise the act of copying. The final decision on whether a solution is recognized as copied or not is solely made by the competition jury.

The jury also considers it cheating when a participant submits someone else’s solution and then independently writes a new solution, meaning the final solution was given for another, non-copied solution.

If participants did not directly use each other’s code but actively discussed the problem solutions with each other or third parties, and the jury discovered this situation due to similarities in the code solutions, this case will also be classified as non-independent completion of the tasks, and the violators will be subject to similar sanctions.

1. In the case where two participants submit identical (possibly modified) solutions to the same problem, all solutions for that problem will be invalidated for the author of the solution (considered to be the participant who submitted it earlier), and the borrower (the participant who submitted the solution later) will be disqualified.
2. If any participant is documented as having allowed cheating in two or more instances, that participant will be disqualified. This rule also means that if participant A gave code to participant B, and then participant B gave code to participant C, all three participants will be disqualified in the end.
