Some advice on div3
By majiamajia55, history, 3 years ago, In English

There has been no div3 competition for more than a month. I thought about it. The author of div3 is limited (it is fixed), and there is no coordinator. Is it possible to change it? Open the question-making authority of div3 to everyone. My idea is to have a div3 question bank, and everyone can propose their own ideas on it. You can choose the estimated difficulty value yourself. However, such a large number of topics certainly cannot all be handled by the coordinator. My preliminary idea is to open the permission of preliminary review to all users with red name and above, as well as past authors. For a favorite topic, the preliminary reviewer can give it a score and an estimated difficulty value. In this way, the estimated difficulty value of each question is equal to the average of the estimated difficulty values played by all the players, and the score of each question is equal to the sum of the scores of all players. Then, at regular intervals (such as a week), the system will automatically push the five questions with the highest scores in each difficulty range to the coordinator for selection by the coordinator. After the coordinator selects a satisfactory topic, the author of each topic will be notified to prepare a topic on the polygon. Then a new div3 is completed! It's just a preliminary idea, everyone is welcome to add it.

I think that it would work if only few people have access to the bank,because it would be unfair if you solved your own problem,but yes,I support this idea

There are actually many problems with this solution, such as: 1. Open to all users, users may propose a lot of problems with low quality. My idea is to add a delete button, if you don't like this idea very much and think it's bad, you can click it, and when the number of people who click delete exceeds the threshold (depending on the current score of the question), it will be deleted from the question bank this problem. Every week is a cycle, push candidate questions to the coordinator every week, and the questions that are not selected will be cleared. If you want to try again next week, you have to propose.2. This is the most important point, other questions It may be possible to solve it through technical means, but this problem may not be. That is, if your question is not selected, you want to propose to other places, and it is selected again, how can you ensure that people who have read your question will not come to the competition? How to ensure that people who have seen your question don't steal your idea? Maybe codeforces has technical means to save the ids of all people who have seen your question, and can notify them when the time comes, but this may be unavoidable.
