Dear participants!

Congratulations on joining the ICPC 2020 Graph Mining Challenge powered by Huawei! All were truly amazed by the participation and quality of the solutions. Congratulations to all of the winners! You will be contacted soon about your prizes.

The competition was so fierce that ICPC U and Huawei have decided to keep the fun going by starting a new, one-week challenge with all new prizes. The problem and graphs are the same, so you can build on your previous success. All are encouraged to participate in this challenge. You may only win one prize from the entire ICPC Graph Mining Challenge events (all combined). If you place in multiple challenges, you will be able to pick the prize you prefer.

Many of you might have been following the Challenge tutorials on ICPC U page. If you didn’t — we’re delighted to invite you to do so in order to sharpen your problem-solving skills and applying it during this additional ICPC challenge week.

As always, ICPC U invites everyone to Train, Practice, and Perform!

Hello everyone!

Announcing the ICPC Graph Mining Challenge, Powered by Huawei and brought to you by ICPC U. Graphs are a powerful mechanism for representing many aspects of our daily lives, from mobile call routing to disease tracking. Answering various graph-related questions enables solutions to some of the most challenging, modern problems. The ICPC Challenge presents a problem from some area in computing. The area and problem style may be very different from the standard ICPC problems. Previous contests included new programming languages, multi-agents, parallel programming, etc. The ICPC Challenge provides a platform for ICPC to experiment with new problem types. It also provides participants with experience in some new area and problem type.

The ICPC Graph Mining Challenge will take place online during ICPC Day Zero on 27 June, 2020, 11:00-14:00 UTC. This round is unrated for all participants. Day Zero is a celebration of the 2020 ICPC World Finals, hosted by the Moscow Institute of Physics and Technology (MIPT). Everybody is welcome to participate. This is an individual competition. Participants will be divided into three groups: 2020 ICPC World Finals Contestant, 2020 ICPC World Finals Coach (includes co-coaches), and Participants. The 2020 ICPC World Finals Contestants and Coaches with the best graph solutions will be recognized as ICPC Challenge Winners. The top-scoring participants will also receive great prizes.

Huawei will provide prizes to the 12 winners in each group accordingly:

• Group 1: 3 hour Challenge — ICPC 2020 World Finalists
• Group 2: 3 hour Challenge — ICPC Coaches and Co-Coaches
• Group 3: 3 hour Challenge — All participants

Each participant may win at most one prize for this Challenge.
