详细介绍Codeforces

简介

Codeforces是一个由俄罗斯萨拉托夫州立大学建立并维护的算法竞赛网站,优势在于其频繁且高质量的在线比赛。
网站提供英语和俄语两种语言。但是由于出题人的多样性,可能会出现少量不标准的英文,这种情况下,俄文在Google Translate中转成英文的效果也是不错的。

赛制

Codeforces自创了一套独特的赛制。这套赛制类似于标准的ACM赛制,但是相比ACM赛制又更加的多样化。

积分

新用户注册后的初始积分是1500。
在一场比赛后,每个选手的积分会根据这名选手(或者其所在的队伍)在本场比赛中的分数和排名按照特殊的公式重新计算。

每个用户的头衔以及昵称颜色取决于你的积分
