2026年紫彗星數學競賽（Purple Comet! Math Meet）變更說明

紫彗星數學競賽2026年比賽的流程有多項調整，并對部分規則進行了修改。

監考老師(Supervisor)賬號登錄方式變更

監考老師(Supervisor)的賬號登錄方式發生變更 ——?過去由官方分配 ID 和密碼,現在改為使用注冊監考老師賬號時所填寫的郵箱地址作為登錄 ID。若忘記密碼,可通過頁面上的?"RESEND PASSWORD"(重發密碼)?按鈕找回。

計算工具使用政策(新增 AI 禁令)

本屆賽事允許使用計算器和計算機進行數學運算,但明確禁止使用生成式人工智能工具(generative AI)—— 包括但不限于?ChatGPT、Gemini、Copilot、Claude?等,不得用它們生成、解釋或驗證答案。參賽學生必須獨立思考解題方法,自行決定解決方案。

?取消 150 英里距離限制(Distance Rule)

本屆賽事取消了原有的?"隊友之間必須相距 150 英里以內"?的地理距離限制(Distance Rule)。官方說明:"Purple Comet! Math Meet 希望鼓勵學校之間的良性競爭。在互聯網通訊如此便捷的今天,以地理距離限制隊伍已經沒有太大意義,因此本賽事決定取消這一距離規則。" 由不同學校學生組成的混合隊伍現統一歸入?MIXED TEAMS(混合隊伍)?組別參賽。

Changes to the 2026 Purple Comet! Math Meet

The Purple Comet! Math Meet website at https://purplecomet.org has been completely rewritten in preparation for the 2026 contest. In addition, there have been several changes to procedures and some rule changes for the contest.

Supervisor Login

Before 2026, supervisors were given a login ID and password to use to log into their supervisor accounts. This has changed. A supervisor’s login ID will now be the email address that they used to register their supervisor account. All passwords have been changed. A supervisor wanting to continue using their old supervisor account can be sent their new password by clicking the RESEND PASSWORD button on the supervisor login page. New supervisor will now be asked to enter a name, email address, city, and country, and can optionally enter a school name and telephone number. When a supervisor creates a team, the school name and location information will default to agree with the supervisor’s information, but these settings can be changed for each team.

Use of Computational Tools

Although the problems in the Purple Comet! Math Meet are designed so that they can be worked without the use of calculators, students are welcome to use calculators or computers to help them perform computations. Students may write computer programs or use computer tools for the purpose of making calculations or drawing diagrams. These tools can include programs available on the students’ computers as well as calculating tools available online such as spreadsheet programs, WolframAlpha, Mathematica, Maple, Desmos, Derive, or GeoGebra. Students may use books and other reference materials such as class notes as long as the materials are available to them at the location where they are participating in the competition. Students may not use the Internet to find needed definitions or instructional materials that tell them about how to solve problems. Students must produce their methods for solving problems and can only use calculators and computer tools to make calculations. In particular, students may not query their Internet browser about how to solve a particular problem, nor may they use generative artificial intelligence tools (AI) including but not limited to ChatGPT, Gemini, Copilot, or Claude to produce, explain, or verify answers, interpret problems, or generate computer code, text, or mathematical reasoning. That is, students must decide how to solve the problems, but they can use computer tools to aid their calculations. The Purple Comet! Math Meet does not allow any tools that inform students about the methods they should use to solve problems or allow students to solve problems without knowing the methods needed.

The Team Member Distance Rule

In the past, the Purple Comet! Math Meet required that all members of the same team must live within 150 miles (240 kilometers) from each other. The purpose of this rule was to discourage countries from gathering their best students to form a team that would likely achieve the highest score in that country. The Purple Comet! Math Meet wants to encourage healthy competition between schools. In this day of easy Internet communications, it makes less sense to restrict teams geographically, so the contest is dropping its distance rule. Teams formed with students who attend more than one school should be entered in the MIXED TEAMS category, which is designed for that purpose. Teams still need to be registered from a particular country, and within the United States of America, be registered from a particular state.
