Any plans to host this contest mirror? Yandex or Codeforces?

So far I thought that the number of lost points per minute is calculated by formula initial_cost / 250. According to this post I'm correct. But after some lookup into standings of last contest I found some contradictions:

• Problem А (500 points): 1 point per minute
• Problem B (750 points): 2 points per minute
• Problem С (1000 points): ~2.67 points per minute
• Problem D (1500 points): 4 points per minute
• Problem E (2000 points): ~5.33 points per minute
• Problem F (2500 points): ~6.67 points per minute
• Problem G (3000 points): 8 points per minute
• Problem H (3500 points): 9.33 points per minute
• Problem I (4000 points): 10.67 points per minute

That definitely says that I was wrong. I'm not complaining about format or something else. Just want some explanation of exact formulas. Am I missed some new clarification on that thing MikeMirzayanov?

P.S: just seeking for explanation after no answer on comment. Constants was calculated from great performances of boboniu and maroonrk.

Given two weighted trees. f(x, y) — distance between x and y in the first tree, g(x, y) — distance between x and y in the second tree. How many pairs (x, y) such that x < y and f(x, y) < g(x, y). Number of vertices <= 2*10^5.

There some strange things happen with problems on Topcoder. Problem statement page is empty, but it can be seen in arena applet. And this happens for many problems. Some examples: link link link link. Is this known issue?

Hi everyone!

4 Europe Regional contests out of 5 was already passed. Depending official information 15 teams from Europe already passed to World Final. Congratulation!!!

I added one of them to Gym. On official website there is only test data and jury solutions. Unfortunately, there is no checkers. Feel free to fix bugs :)

Time constraints was assigned depending on execution time of jury solutions. On official contest there was very high time limits, maybe because of Kattis servers.

Added contest to the Gym. On website I found only tests. And checkers was prepared on my own, feel free to fix. Does anybody have jury solutions?

Let's discuss problems.

How to solve E and F.

Hello Everybody, I have a question. How do you train to improve your problem solving skills? Which problem archives are you solving? About me: I solve problems from lightoj to improve my skills from determined topic and I love solve from codeforces gyms.
