About the Challenge
The IMC Challenge powered by Huawei is an international program jointly initiated by Huawei and the International Mathematics Competition for University Students (IMC). This program gives math enthusiasts the opportunity to tackle real-world math problems faced by the industry, builds bridges between theoretical research in mathematics and the industry, and provides a platform for the exchange of ideas.
Huawei's support for this program is part of its ongoing commitment to opening up its research platforms that focus on future information terminals, computing, and connectivity. Huawei has and will continue to create opportunities for the next generation of problem solvers, as they explore challenging subject areas that advance science and technology and drive the industry to meet the needs of tomorrow.

About the Problems

This Challenge covers 2 problems. Each problem will be released on a different date and have its own reward plan. Contestants can choose to work on one or both of the problems.

Problem A

High Speed Signal
Simulation and Equalization

Problem B

Coming Soon

Problem A

High Speed Signal
Simulation and Equalization

Problem A introduction:

As a key link in chip-to-chip communication, high-speed interfaces play an important role in computing, network, wireless, and terminal fields. Due to the non-ideal characteristics of analog or optoelectronic devices and channels in communication links, the received signals are accompanied by specific impairments. As the transmission speed continues to evolve, end-to-end links also contain strong non-linearity and noise. More and more complex damage makes system analysis and algorithm design more complex. In view of the above background, we hope that the contestants can decompose the signal damage, accurately model and analyze it. Under the specific input data, the modeling estimation and fitting of the signal waveform are carried out, and the original data are recovered from the analog waveform by algorithm. In order to meet the requirements of low power consumption, low latency and low bit error rate in the actual communication system, the problem must be completed within the limited complexity and accuracy.

Problem B

Coming Soon

Problem B introduction:

In the field of information technology, the issue of generating and jointly processing multi-dimensional data is becoming increasingly common with the enhancement of hardware deployment capabilities. There exists one category of classic issues in this area, known as subspace analysis. It includes analysis on the characteristics of data space to obtain essential information on low dimensions and also includes subsequent processing (such as enhancement or suppression) of this information. This topic focuses on an important issue in subspace analysis: accurate separation and estimation of target linear subspaces in a full-dimensional matrix space. At the core of this interactive topic is to explore the design of solutions for separating and estimating target linear subspaces. As the target linear subspace may be obscured by interfering linear subspaces (that is, other components in the space), participants need to accurately separate and estimate the target subspace with a black box system (linear-nonlinear-linear system). The difference between target and interfering linear subspaces is their respective spatial characteristics. The input design of the black box system can help accelerate the subspace separation and estimation. Note that this topic requires participants to design solutions within a limited complexity (program running time).

Contest type

Team competition + Coaching

Team formation: Each team may have at most four people, including a team leader.

Team leader: The team leader creates the team. As the team's contact person for the organizers, the team leader shall receive any prize money on behalf of their team.

Coach: This Challenge provides a coach reward plan, which encourages participating teams to invite domain-specific teachers to act as coaches and help the contestants improve their problem-solving skills during the contest. A coach cannot be a contestant on the team. Failure to provide coach information during registration is deemed as a decision not to participate in the coach reward plan.

How to Register

Step 1: The team leader scans the registration QR code or visits the contest platform at https://imc25.kattis.com/, then clicks “Log in to the contest” to register or log in with an existing Kattis account.

Step 2: After logging in, the team leader returns to the contest page and clicks “Join the contest” → “Create a new team” to set up a team.

Step 3: On the“Teams” page, the team leader clicks “Invite” → “Generate invite link” to create exclusive invitation links and sends it separately to team members and the coach.

Notes:

Please read carefully the “Conditions and Rules of Participation” and the “Pravicy Policy before registration.

Submissions, Winner Selection, and Prizes
Submissions,
Winner Selection, and Prizes

During this Challenge, there will be two rounds of winner selection and prizes for each problem. In Round 1, winners are selected based on their code. In Round 2, winners are selected based on their code and articles. This section provides information about submission requirements, winner selection rules, and the prizes for Round 1 and Round 2. For more information about the timeline of each problem, see the "About the Problems" section.

Notes:

(1) Given that writing an article takes time, the last day of article submission is 10 days later than the last day of code submission. Please keep the deadline for article submission in mind and make necessary preparations.

(2) If submissions are found to be too similar during the review, the relevant teams may be disqualified.

(3) Applicable time zone for all problems: UTC+08:00.

Outstanding teams in Round 1: Top 18 teams

(1) Contestants log in to Kattis to submit code for the problem before the deadline.

(2) The review team for the problem performs a review based on the rank lists on Kattis, and announces the list of winners in Round 1 on this website. See the “About the Problems” section – Problem timeline – Round 1 results released.

(5) Coach reward plan for the coaches of outstanding teams in Round 2:

Within two weeks after Round 2 results are announced, coaches of the top 10 teams should submit a summary of their coaching experience using the template to challenge4IMC@huawei.com. Failure to provide a summary of coaching experience on time is deemed as a decision not to participate in the coach reward plan.

(6) The Round 2 results will be released on this website. See the “About the Problems” section – Problem timeline – Round 2 results released.

In addition to the above prizes, the top 100 teams will also be given opportunities to meet Fields medalists and problem authors face to face, and visit Huawei's campuses around the world.
