Peru has participated in the IOI for the first time and has won a bronze medal. (orz NRolly)

I am the coach of the whole team and we will probably qualify again next year. Our goal now is to get a silver medal in the future. That's why I would like to know how is the training in other countries. How many hours do you dedicate to training? How many contests do you simulate per week? Do they enter codeforces, codechef, atcoder?

Clearly getting a silver medal is not easy but we want to try.

We will be grateful for your support. Best regards

 » 6 weeks ago, # | ← Rev. 2 →   +110 In Poland, we rely primarily on high schools and contestants themselves. Some prestige schools run regular classes on algorithms and data structures. I used to be a teacher in one of such schools and got 2-4 hours of classes weekly. During the classes, we were exploring basic topics (starting from binary search, through segment trees to centroid decomposition). I also gave them a lot of homework in form of problems from old competitions, and once or twice a month a full 5-hour contest. I encouraged people to participate in Codeforces and AtCoder, but as the IOI problems are significantly different from the problems from these platforms that was not a hard requirement at all. Everything that I said is just required to get to the final stage at the Polish Olympiad and then be selected to the IOI. After that, the ball was in the contestant's court. I still tried to help them by providing interesting problems from which they can learn something new, but it mostly depended on them. The Polish Olympiad helps a bit -- we have a summer training camp, but that's mostly it (unfortunately).The one piece of advice I can give to you is you have to make sure that the students are motivated. It doesn't matter how many problems you have solved. You have to be passionate about problem-solving and have some fun doing it. It helps a lot when you form a group of people that can learn together and compete against each other.Hope that helps!
•  » » 6 weeks ago, # ^ |   +8 Thank you very much for answering!In those classes, only you taught? That is, the students only had theory class 2-4 hours a week?I'm not sure if it's correct to ask the following but... How was the training after qualifying to the IOI?Finally, how can I improve as a coach? Honestly, several times I feel that I am not qualified for this job.

For some time I shared these classes with one more person (I had 2 hours and he had another 2). How was the training after qualifying to the IOI? Mostly I was suggesting to them problems from old national/international olympiads. Very rarely was I also needed to find/come up with a solution to some problems. Finally, how can I improve as a coach? Honestly, several times I feel that I am not qualified for this job. Don't worry, everyone experiences impostor syndrome. But I have to say that I also learned a lot about how to teach by preparing for the classes and even during them, just by practice. It also helps a lot to also watch other teachers, even by checking out some YouTube videos. Estoy seguro de que estas en el top 3 de los mejores maestros posibles en tu pais!

•  » » 6 weeks ago, # ^ |   +37 Soooo hard :/Just go to the gym (the real one, not CF gym) and do the power trainings. Year after the teammates will be so strong, that will easily steal 4 golds from Chinese members XDDDD.

(sorted in difficulty)If you need only the problems in CCF-NOI series, use https://hydro.ac/d/ccf/p. The problems with English names are translated to English.Sadly, only a small amount of the problems are translated to English. The organisers of HydroOJ are still working on this. You can use translation software for temporary use.

 » 6 weeks ago, # |   0 I recommend that the div1 virtual contests team and then do upsolving (it is allowed to see the tutorial) of the problems at least until E every day. A simulated 5 hours per week would be fine too.This could help to have an order to perform the contest div1. https://contestmania.web.app/codeforces?category=Div1
 » 6 weeks ago, # |   +38 Hi, I participated in this years IOI. I didn't win any medal, but right after every contest I knew a lot more solutions to subtasks which would eventually have led to a silver medal. The thing I lacked the most was time management and 5h contest experience. I didn't train more than 1 to 2 hours a day.I'd suggest for future trainings to let the students get used to these kind of contests and also let them feel when they should stop thinking of a problem and go to the next one.I hope this helps :)
