I happened to participate in the ICPC 2017 online round yesterday, and I just thought I’d record my opinion on this forum.
First and foremost, the contest was not at all conventional. There was a stark difference between last year’s Online Round(which had an assortment of problems from DP to Graphs to Greedy) and this year,which was just high on math. Was this comfortable for the majority? I believe not. So, do you call the contest bad? No. Recently, there seems to be a cognitive definition for contests in general, and anything that doesn’t follow this pattern seems to be frowned upon (Case in point : Codeforces Round #444 (div2) ). This contest, for sure, thoroughly emphasized on why one has to be strong with mathematics to excel in programming.
With regard to the issues of cheating and discussion on StackExchange, well, I guess nothing can be done about it. Its going to be extremely unfair to the ones who actually solved it, yes. But I don’t think there’s any plausible solution for such an issue. I saw quite a few people requesting for a recontest , but honestly, that’s never going to happen guys. Issues did crop up last year as well, but they were simply overlooked. I do hope there’s some other way out of this menace, but a recontest will never ever workout. To the ones who might accuse me of supporting “no recontest” for selfish reasons, nope. My team may not make it to the regionals this time for all we know.
Why are the solutions hidden for all teams? I request @admin to make all solutions public, and also to add the problems to practice section along with editorials if possible.
