Too few div1+2
By Ssoul, history, 4 hours ago, In English

Div1+2 are too few compared to div2/3/4. I don't want to participate unrated contests. Can div1+2 be more? Can orange be rated in div2?

What's wrong with your rating graph? I don't see your last few contests I think.

Div2 contests were originally rated for Experts, then they found that it's challenging for CMs as well, so they made CMs rated for division 2. I think what we should do is not infinitely extend the rated range of division 2, but instead preserve the harder problems for div. (1 + 2) contests.

In many recent contests, the last problem is often challenging even for grandmasters (and most official solves come from alts). I think these problems should be in div. (1 + 2) contests instead of being "wasted" in div. 2, although I don't know how the system really works so I have no idea whether the harder problems could be proposed for other rounds individually or not.

    You have a point. But if rating beyond 2200 can only participate 2 or 3 rated rounds a month, they will register more accounts to enter more rated rounds. It feel different between rated and unrated rounds.

    The standards for div1+2 rounds and div2 rounds are different. Not all hard problems in div.2 can go in div. 1. Problems that are deemed standard for div.1 participants may be educational in a div.2 round.

      I can see where it comes from, but to be honest I don't think these Div. 2-only F problems were not really that standard compared to F's in Div. 1 + Div. 2 rounds. I personally see no issue having them in Div. 1 rounds, and it's probably more of an issue of having too few coordinators who can coordinate Div. 1 rounds.

        You don't find it standard because you are not red, div-2 F is hard but it is still standard for a lot of red's. Have a look at problems from Atcoder Grand Contests, even problem A can make IGM's struggle, those problems require no advanced data structures or advanced concept, just purely observation-based but it is tough enough to make people struggle. I don't think people can come up with those kind of problems on regular basis.

          Why would you compare this with Atcoder though? If F problems in Div. 2-only rounds are not standard compared to Div. 1 + Div. 2 rounds' F problems, then it's either that both can be in Div. 1 or both shouldn't be in Div. 1, don't you think so?

Div 1+2 sucks, a lot of bullshit problems where master+ can easily speedrun. It is only good for those who are masters and desperating to farm some more rating to become GM LOL. They'd better seperate them into two constests like the old days.

On a related note, what happened to the div1-only round? Why is every round that is rated for div1 a combined round? I get that some of them are sponsored, but what about the non-sponsored ones?

    It is not easiy to write quality problems for div-1 contests, that the reasons while high-rated contests are becoming less and less frequent. On the other hand, it's much easier to make problems for div2, you can just take ideas from few problems, extend it or mix them together and you get a new problem. How to make it so that high rated ones can also participate? just throw two more extremely hard problems that only LGM solves and we get div1+2.

      My comment was about rounds that are rated for everyone but that are split into two parallel rounds: one is for people rated below 1900, the other one for people above. The reason I think this is better is that div1 users start from div2C rather than div2A so they get more time to work on harder problems.

      Regarding your point, a div1+2 round can basically be turned into separate div1 and div2 rounds, for the former you just remove the two easiest problems; for the latter you just remove the two hardest problems.

    For now, the main problem about Div. 1 is the lack of coordinators, not the lack of good proposals. So most of the proposals we review are good enough to be sponsored. But sometimes no sponsor is available, so it all depends on the sponsors' availability.

From what I talked with coordinators, it seems like the main reason there aren't more div1s is that they're harder to do, which makes sense since the stakes are higher and the problems are harder.

I think, that one of the main reasons is the creation of div 1 E (the last problem). I can create problems up to ~$$$2800$$$, but have no idea, how to create $$$3500$$$.
