The solution for Codechef problem chef and the railway stations is shared on stack exchange, and its not about long challenge, those who cheat also do the same in a 3 hour challenge, its about learning and not “RANK”

This seems the best solution to this problem
Codechef already provides separate ratings for long, cookoff and lunchtime.

You can’t possibly tell me long challenges aren’t the most fun to do. Tbh I could care less about cheaters. I just assume everyone has done the best to their own ability and if they did better than me, they were probably better than me. Long challenge is where you can actually learn different techniques, rather than just quickly implement something you already know, try different approaches and learn to think in new ways. I have learnt almost everything i know in the three long challenges I’ve given. I’ve spent a considerable amount of time on all 3. It incentivises you to read about differnent techniques, which you wouldn’t find in a standard short contest question. Moreover, in a lot of the sums, There is much to be explored with a lot of different properties you find while trying it out. I don’t think i would have put that much effort on an unrated contest, would I?
To me, my long challenge ratings are most important because that’s where you actually need to spend some time to figure out unconventional methods to solve questions.

Well, in long challenge you get 10 days to cheat as opposed to 3 hrs in short contests. So its easier to ask on some platform and wait for a reply or make groups and ask for ideas.

Codechef already has 3 ratings. The main rating should be based on only lunch time and cook-off contests or give less weightage to long contest ratings.

Well long challenge’ isnot competitive anymore. Plus in the industry you would know that, interviews are just like short contests as well. I think you haven’t realised it well.
Yes exactly what I meant .
I suggest you to do codeforces, you’ll actually realise where you actually stand. Plus won’t take much of your time like 2 hours a day, that much time a professional spends on coffee break every two days at job

As mentioned, I’m careless about where I stand or any kind of competitiveness. It’s just for pure fun. In the last year long div 2 is full of math/puzzle kind of problems (as @ashukr97 mentioned), which are fun to solve but could barely validate anything, which your point is. I used to be a student with a CP dream like many here, and now it’s just for the nostalgia.
It’s quite difficult for many of us to dedicate a whole 3 hours at midnight on anything that we’re not aiming to get, and for me, it’s CP. But in 10 days I can be arranging 30 minutes every now and then and that’s completely fine.
If the problem is the cheaters, then we need to try to solve it, not to blame the format. I agree that having separate ratings (or no ratings at all) for long challenge might help. CP is about skills, and something one does in 10 days does not prove anything other than dedication. The ranking during contest can be kept to maintain the fun, but the rating system is seemingly misunderstood and abused by some and thus should be reconsidered.

I agree there are issues. But, Long challenge is designed to encourage users to learn new concepts & help beginners to get started. So, making 3-5 questions hard doesn’t make much sense.
