在大家翘首以盼下，USACO首场竞赛今日12月15日正式开赛了！具体赛程安排如下：（图自USACO官网 usaco.org）
为了确保比赛的公平性和减少考试的作弊行为，官方公布了最新的竞赛规则，其中进行了几项内容上的重要调整👇
01禁止使用生成式AI（eg.Copilot或ChatGPT等服务）。USACO组织方明确表示，在比赛过程中，所有参赛选手都不得使用生成式人工智能来辅助解题。
02美国地区的学生需遵守不得使用VPN来隐藏IP地址的规定，以确保比赛的公平性和真实性。也就是说，你的IP地址应该是你的学校或家庭互联网服务提供商的IP地址。
官网原文 ⬇️
USA students should not use VPNs or related technology to obscure their IP address during a contest (i.e., your IP address should be that of your school or home internet service provider)
03特别注意的是：
1）需要认证白金级别的学生必须在规定时间（周六美西时间9:00至9:15、美东时间12:00至12:15）内开始考试；
2）希望入围国家集训队（as a finalist）的学生应尽量在所有白金竞赛中获得认证分数；
3）考虑到时间安排有时难以协调，获得三项而非四项认证分数的学生仍会被考虑入选国家集训队；
4）如果学生在赛季中期从黄金级晋升为白金级，而认证分数少于三项，也可考虑入围国家集训队（在这种情况下，认证分数越多越好）。

ForUSAstudents participating in aplatinumcontest, you will earn acertifiedscore if you start the contest between 12:00 noon and 12:15 eastern time (ET) on the Saturday of the larger Friday-Monday contest timeframe. Certified scores carry more weight during finalist selection. This special timing currently only affects platinum contests, not other divisions. That is, platinum problems become available only at noon ET on the Saturday of the contest window; all other divisions can be launched earlier, on the Friday morning of the Friday-Monday contest timeframe. Students who wish to receive full consideration for selection as a finalist to attend our training camp should try to receive certified scores on all of the platinum contests. Realizing that schedules are sometimes hard to coordinate, students with three instead of four certified scores will still receive full consideration. Students who have fewer than three certified scores due to promotion from gold to platinum mid-season may also be considered for finalist status (in this case, the more certified scores, the better).
预祝所有参赛同学们都能取得满意的成绩。
