1. Should I pay any registration fee in order to participate in the contest?

No. In this year, for participants from regions other than mainland China and Macau SAR, their registration fee will be waived off.

2. Should I register for the contest? How to register? Can I update my registration information after registered?

Yes. Please register through this website before the deadline as specified at this website (usually two days before the contest starts).

A team should consist of up to three undergraduate students guided by at most one advisor (optional).

For register, you should "sign up" an account in this website at first, then provide registration information for your team through "Membership" menu. Please note that each team should "sign up" only one account and should input all the information of the team with this account through "Membership" menu. Please also note that your own information should also be included in the members (students) list of your team.

In any time before the deadline of the contest registration, you can update your team's registration information following the same procedure of registration (i.e., log onto the system, then open the "Membership" menu, and click on the "Register" columm to update your information).

3. Should the team members be from the same institution?

Yes, all the three students and the advisor (optional) for a team should be from the same institution (college or university). But they can be from different depatments and/or majors.

4. What is the difference between the categories (contest types) of "University" and "College"?

The students from three or four-year universities should register as a univeristy team, and the students from two or three-year colleges should register as a college team.

Starting from 2019, a univeristy team should choose one problem from A, B or C from the contest problems; a college team should choose one problem D (or E) from the contest problems.

5. How to download the contest problems and submit a solution package? Can I resubmit a new version after submitted?

Please download the problems from this website after the contest starts, then work on one of the two problems in your registrated category (contest type), and finally upload your solution package before the contest ends. Please upload your solution package as a single file (you can use WinZIP or WinRAR to compress multiple files into a single file for uploading). Each team can submit one (and only one) solution package for only one contest problem.

If you have problems when you download the contest problems (the webserver is usually heavy loaded at the time the contest starts), please send an email to Prof. Jinxing Xie (email: xiejx@tsinghua.edu.cn). We will then send a copy of the contest problems to your via email.

In any time before the deadline of the contest, you can update your solution package following the same procedure of submission (i.e., log onto the system, then open the "Membership" menu, and click on the "Submit" columm to resubmit a new version of the solution package - the old version will be replaced by the new one).

If you have problems when you upload your solution package via the website, you can also send your solution package via email to Prof. Jinxing Xie (email: xiejx@tsinghua.edu.cn).

6. What should a solution package include?

A solution package is a set of electronic documents, and usually consists of the following electronic files:

(1) A cover page file with participants' full names and addresses, separated from the solution paper file.

(2) The full solution paper file (with paper title, abstracts, full text with multiple sections, references, appendicies, etc., but do not reveal your affiliation or personnel information);

(3) Other relevent materials you think it's helpful to evaluate your solution paper (e.g. the source files of computer programs you used to solve the contest problem, etc.).

  The solution paper should be written in either English or Chinese, and uploaded as a PDF-format file (preferred) or MS WORD-format file (compressed into the solution package).
