Greetings!

Ugh! That guy comes with another online-mirror and ruins my timeline again.

Here is the last one this year I could share with you, 2018-2019 ACM-ICPC, Asia Jiaozuo Regional Contest. It will start on Saturday, December 8, 2018 at 17:00 (UTC+8) and last for 5 hours. You are able to register 6 hours before the contest starts. However, before the registration starts, you may not view this contest on Gym. By the way, other Asia east continent regional contests shared by my friends and I could be found at Nanjing, Shenyang, Qingdao, Beijing and Xuzhou.

This onsite contest was held by Henan Polytechnic University on November 25th. It is the first time one regional contest was held on HPU, but it is quite memorable. Among the above 6 regional contest, I could definitely say Jiaozuo is the second easiest one. Though it may contain a few hard problems, several problems are solvable for beginners.

The problems are prepared by AHdoc, Claris, quailty and me. Thanks to zscc for discussing ideas, yefllower and niike0goood for testing, and MikeMirzayanov for developing wonderful platforms and kindly answering technical issues.

There is one thing we need to point out again. For everybody who has already read the problems, please do not to participate in this online-mirror contest or discuss solutions before the contest has ended. We have shared solution sketches (in simplified Chinese) in this site, so if needed, we would share some hints (in English) after online-mirror.

At the end of my post, I sincerely recommend authors of Asia-Hongkong (was held on Nov. 18) and Asia-East Continent Final (will be held on Dec. 16) would share problems with the public at any website. Your efforts should be rewarded!


UPD1: As a kindly reminder, our sponsor Jisuanke will hold another online-mirror contest soon after the contest on Gym, which will start on Sunday, December 9, 2018 at 12:00 (UTC+8) without the onsite board.

UPD2: Contest will start 1 hour in advance, as there is a CodeChef SnackDown contest soon after.

UPD3: Registration starts. You may view this page to register.

UPD4: Hints for this contest are published.

Hello!

This weekend we would like to share an online-mirror of 2018-2019 ACM-ICPC, Asia Xuzhou Regional Contest with you. Please notice its start time is Saturday, December 1, 2018 at 18:00 (UTC+8) and we will be there for answering your questions. You are able to register 6 hours before the contest starts. However, before the registration starts, you may not view this contest on Gym. After the online-mirror contest, you can virtually participate at any time you want.

The 2018 ACM-ICPC Asia Xuzhou Regional Contest has been finished at China University of Mining and Technology, on October 28. Although 288 teams participated in the onsite contest, only 195 of them (including invited teams) finally solved at least one of 13 problems in 5 hours. Is the contest too hard? Or is the difficulty only applied to Chinese participants? We cannot get a conclusion clearly... Anyway, we hope these problems will benefit people who want to gain great results in ICPC.

The problems are prepared by AHdoc, Claris, quailty and me. Thanks to niike0goood and zscc for discussing ideas, yefllower and niike0goood for testing, Syloviaely for playing a crucial role in the contest, and MikeMirzayanov for developing Codeforces and Polygon.

Also, as a kindly reminder, Jisuanke will hold another online-mirror contest that will start on Sunday, December 2, 2018 at 12:00 (UTC+8).

We kindly ask everybody who has already read the problems not to participate this online-mirror contest or discuss any solution in public before the contest has ended. Your cooperation will be greatly appreciated.


UPD1: Registration starts. You may view this page to register.
