Hello codeforces,

link is coming, the event with Bill Poucher and Kazakhstan Team. They have some limited space, and the only requirement is being related to the ICPC community.

P.S: Just wondering is there any ICPC related clubs in Bay Area?

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.

UPD: go here

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.
