The ratings were updated last Sunday, but it turned out that in the old rating system the ratings changed too much in a single contest. We changed the rating formula to fix this issue, and now the rating is calculated based on the new system. In AtCoder, when you participate in only a few contests your rating is much lower than your actual strength (so don't worry even if your current rating is very low). You need to participate in at least 10 contests in order to get accurate rating. We will publish the rating formula in the near future. Here is the table of colors: |Rating|Color| |:--:|:--:| |3600-3999|???| |3200-3599|???| |2800-3199|<span class="user-red">Red</span>| |2400-2799|<span class="user-orange">Orange</span>| |2000-2399|<span class="user-yellow">Yellow</span>| |1600-1999|<span class="user-blue">Blue</span>| |1200-1599|<span class="user-cyan">Cyan</span>| |800-1199|<span class="user-green">Green</span>| |400-799|<span class="user-brown">Brown</span>| |0-399|<span class="user-gray">Gray</span>|

Two contests [AtCoder Regular Contest 058](https://arc058.contest.atcoder.jp/) and [AtCoder Beginner Contest 042](https://abc042.contest.atcoder.jp/) will be held on this Saturday at the same time. You can participate in whichever contest you want. (However, you can't register to both competitions.) The last two tasks in ABC are the same as the first two tasks in ARC. ABC is significantly easier than Div2 contest in TopCoder of Codeforces. If you can enjoy Div2 contests in TC or CF, I recommend you to participate in ARC. - Time： July 23rd (Saturday), [21:00 JST](http://www.timeanddate.com/worldclock/fixedtime.html?iso=20160723T2100&p1=248) - Duration: 100 minutes - Number of Tasks: 4 - Writer：<a href="/user/yosupo" class="username"><span class="user-yellow">yosupo</span></a>, <a href="/user/kyuridenamida" class="username"><span class="user-green">kyuridenamida</span></a> - Rating： ARC is rated for those who have rating < 2800. ABC is rated for those who have rating < 1200. (However, note that current rating is much lower than your actual strength - if you are green or brown, I recommend you to choose ARC.) The point values are: - ARC: 300 - 400 - 700 - 1500 - ABC: 100 - 200 - 300 - 400 You can check the relation between point values and difficulties [here](https://agc001.contest.atcoder.jp/). We are looking forward to your participation! **UPD:** Thank you for participation! **UPD:** Ratings are updated.
