Hello, Codeforces!

The ICPC Challenge World Finals in Luxor is approaching for some of you, and we are delighted to provide an additional exciting opportunity to compete open to all!

We are happy to invite you to the 2023 Post World Finals Online ICPC Challenge, powered by Huawei starting on May 6, 2024 at 15:00 UTC and ending on May 20, 2024 at 14:59 UTC.

In this Challenge, you will have a unique chance:

  • to compete with top programmers globally

  • to solve 1 exciting problem prepared by Huawei

  • to win amazing prizes from Huawei!

It is an individual competition.

2023 Post World Finals Online ICPC Challenge powered by Huawei:

Start: May 6, 2024 15:00 UTC

Finish: May 20, 2024 14:59 UTC

We hope you'll enjoy this complex Challenge!

Problem

We are glad to propose to you an exciting challenge “Accuracy-preserving summation algorithm”, which is prepared by Huawei Computing Product Line.

With this challenge, we focus on summation algorithms of floating point numbers in different precisions with the goal to use the lowest possible precision without losing too much of the accuracy of the end result. This problem arises in high-performance computing as lower precision can be computed faster. At the same time it also loses accuracy faster and can even lose it completely. Finding the right balance between fast low precision calculations and higher precision intermediate summations is a challenging task on modern architectures, and you would have an opportunity to try addressing this challenge

I remembered about a summation problem long ago, but it got wiped out of CF and I can't find it. Now it has came back with a different name.

Should I be registered somewhere else from CF, or CF registration for the event is sufficient to be eligible for the prizes?

    According to para. 8 of the challenge rules, "only participants who entered a valid ICPC username (email address) during registration are eligible for recognition as a Challenge winner", which means (if I remember correctly) that you need your codeforces email to match your icpc.global email. It should be possible to register there even if you are not icpc-eligible (e.g. not a student).

    You can probably avoid this as long as possible and only do this after the contest ends if you are among the winners, though.

There's a lot of minor details about the scoring process that are missing from the statement. Do you plan to release a local scorer to clarify some of them? Thank you

Maybe the next time we will have to write an evaluator for codeforces :)

    Or write a program to predict(guess) a proper time to submit to avoid being inq

Can someone explain which order codeforces judges? I sent submission 1 hour ago. Still in queue while recent ones have been already judged.

I just noticed the grader is extremely fast, can we expect the same performace for the hidden tests?
