Thematic Olympiad in combinatorics. Solutions, preliminary results and first impressions.

We will answer numerous comments all at once. The form was closed at exactly 13:30, as was the case in the conditions of the holdings. Accordingly, all works that tried to send later were not accepted. The fact that works should be sent in one pdf was also mentioned more than once. We also emphasized that something should be practiced if there was no such experience before. 30 minutes is enough to do it all.

In fact, with the help of many applications, this can be done in 5 minutes maximum with the help of a mobile device. If you use the scanner itself, then this time is also enough (tested by own experience). Also earlier, the site published instructions on how to form a pdf file from images.

Please note that at 13:00 the finished work should already be a consecration (as a real oltmpiadi) and all the rest of the time should be spent on sending answers and directly working. Since we cannot trace this, it remains only to make time limits.

Why don't we take a bunch of photos? Even in pdf files there are upside down, smeared photos. What kind of chaos would there be in a pile of photos? And how long would it take to see 350-400 such works? Respect our work, please. Checking the Olympiad is a complex process in which not so many juries are involved.

Conclusion: All the works on which the answers were sent will be in the results. If the student does not have the submitted work at the prize place (that is, we could not check the availability/correctness of the solution), then this line is ojipped and the place is not awarded. All requests for inattentive responses will be reviewed.

Next, you can find preliminary results from combinatorics:
