Hello to everyone!

It’s not the first time I’ve noticed comments such as this one:

However everything remains as it is. There is no visible reaction to such problems. Perhaps the administration has no time to read all the comments. But in that case there should be a place in which everyone would be able to throw off reports about bugs. Unfortunately there is not such a place.

At least three people suffered from this problem at the last codeforces round:

I hope someone from administration will notice this post.

This issue should take top priority over all other issues in my opinion. Isn't this very very high injustice with participants who face this in the contest ?

The entire purpose of a rating system is spoilt if such things begin to happen, and people loose rating in situations they should have gained.

I saw this error many times while I was working with polygon. In polygon, every problem has a Main solution and a test set, the system generates the correct output file using the Main solution, it seems it's a system bug, it failed to create the correct output file.

I think that the judge should skip over test cases where the system fails to produce output.

Similar to the presumption of innocence, where one should be considered innocent until proven guilty. There should be a presumption of correctness, where the system would assume that a solution is correct unless it could be proven to be incorrect.
