 » 5 years ago, # | ← Rev. 2 →   +9 I couldn't solve any of them but I liked boxes and horses the most. Also scales was very interesting.
•  » » 5 years ago, # ^ |   +14 Choosing the best contest strategy is almost 70% of the winning ioi style contest for a ready and well prepared student! BTW I believe it's better not to have online scoreboard! One of the reasons is many people are more relaxed in this situation
•  » » 5 years ago, # ^ |   +72 At least in the next few years the contestants will not have access to the live scoreboard during the contest. The presence of such a scoreboard would change the contest in ways we dislike. We want the contest to be about independent problem solving.
•  » » » 5 years ago, # ^ |   +24 Thanks for the reply! Your logic makes sense, I only asked because I'm used to seeing a live scoreboard and I recently realized I have no real strategy without one. I guess I should work on that!
 » 5 years ago, # |   0 Towns was certainly the best one for me. I liked it a lot and we came up with solution idea just 10 hours after the contest! Scales and teams were also very cool problems. Having said that I solved neither of those three I mentioned, but I still think they were great (costed quite alot of push-ups though)On a side note, will author solutions be posted?
•  » » 5 years ago, # ^ |   +13 Hopefully, yes, but it will certainly take a while -- at the moment, only very short solution sketches exist.
•  » » » 5 years ago, # ^ |   +3 I can post my Java solutions (on the problems where I wrote them) if no one objects
•  » » » » 5 years ago, # ^ |   0 Sure, feel free to post those.(Just to clarify: I was talking about English solution writeups, not about code.)
•  » » » » » 5 years ago, # ^ |   0 Yeah, maze was less of surprise than languages, especially after languages in the first day. My issue with maze was that it was second (+ 1/4 of hottercolder) approximation task in the competition.As for languages, I'm not denying that I failed this task miserably by perhaps panicking, but here is my experience during the contest with it: Implement what is written in the statement for 55 points While contest is not over: Think of improvement I Implement I Receive less than 55 points Delete I
