Migration to new judging system

[namanlp]

Hi @admin ,

I am just curious what’s new and better about this new Judge. And what are drawbacks as compared to previous codechef as well as present codeforces judge / other equivalent websites judge.

Thank You

[admin]

Hey, we’ll write a detailed post about this when things stabilize. Right now, we are still migrating and building various components.

For now, a short draft:

Pros:

• Gives us more flexibility to do stuff, so eventually shorter time frames to fixing and building new features.
• Lower cost. So the platform lives longer

Cons:

• Fewer languages will be available: C++, Python3, PyPy3, Java, C, C#, JavaScript, Go, Kotlin, Rust. Other languages will be added over time.
• Some problems (mainly interactive and challenge problems) will not work for now. We will enable support for them over time.
• Time limits for old problems are tweaked to correspond to the new judge, but might not be perfect. We try to err on the side of safety, so some sub-optimal solutions might pass in rare cases.

Hi,
Looks cool. Thanks for quick response.

Eagerly waiting for next contest

The new checker will check all the test files as it was previously or will terminate as soon as WA is found?

So are we going to witness changes in our existing ratings ?

[hrishik85]

@reyan_cr - no.
The rating system is not changing.

I anticipated that Codechef would celebrate the 100th starter with the introduction of the new judging system.
Sincerely,
An eager contest participant awaiting the commencement of the contest.

Why is lunch time and long challenges discontinued?

Important Update

Some more details about what exactly the changes in our contests will be: We are pausing Cook-Offs, Lunchtimes, and Long contests Starters will continue as they are, with some of them now being rated for all. Most contests will be for 2 hours instead of 3 hours. The difficulty of the hardest problem of Division 1 will be a bit lower than before. But for all the participants in Div-2, Div-3, & Div-4 there will be no difference.

When will be the contests available as before?

@admin

Other languages will be added over time.

Do people need to request new languages if they want to see them supported on CodeChef?

[admin]

Requesting will probably push that language up our priority list

[dilip0409]

Because many cheat in long contests and their rating increases without much efforts…

[jainmilind]

MLE are being classified as Runtime Error

[admin]

That has always been the case. Can you point to any particular instance where you think something is wrong/different?

[vanshwari]

when will interactive problem be available?
as they are disabled for long time
