This problem: https://codeforces.me/contest/733/problem/E
is the exact same as this one: https://codeforces.me/contest/1936/problem/B
except the former one is like 8 years older than the latter one. The former one is rated $$$2400$$$, while the latter one is rated $$$2000$$$. Does this mean that a candidate master today would've been a grandmaster 8 years ago?

When knowledge is more freely available, people become better
Damn, I wanted to upvote but missclicked downvote. Sorry man.
It's ok. Just make sure to do better in the future.
Mike should implement undoing a down/upvote, or at least if you downvoted and then upvoted the upvote should undo the downvote and vice versa.
Do not worry, make an alt to upvote it.
I think it's a combination of people getting actually better and the tendency of harder problems being overrated. Note that the former one is an E problem, so most people had to spend most of the time on A-D already, and there were not enough time left for them even to try E.
And we try hard for B(assuming it's solvable), but not much for E(assuming it's hard).
Also, in the old days when the pretests are weak, it's possible someone with an almost correct submission to be hacked/FST, and they won't be considered solved the problem during the contest. Hence affecting difficulty calculation.
You are comparing div 2 to div 1 which is not that fair. Also, the problem statement is rather long on the first one.
So that div2E problem it's like a div1C?
When div 1 + 2 rounds happen, div. 2 E is usually the same as div. 1 C. But -is-this-fft- says that div. 1 C's are usually less standard than regular div. 2 E's, so they aren't exactly the same.
People of the past had a skill issue
That's why People of the past can't cross 4000+ rating... You know who !!!
xD. Hope you get Sarcasm.
Because it's a binary search, even with hard implementation.
I believe it's true I was able to solve few 1900 problem without looking editorial or other ppls code but that's not the case for recent 1900. See problem like 2021C2 - Координация презентации (сложная версия) or 2002D1 - Проверка DFS (лёгкая версия) compare to 1900 problem from 6xx, 7xx cf round it's actually insane. 1900 problem in past more like 1700 nowadays.
I've noticed that too. Older problems also seem to use a bit more DS/A.
Just saying this problem is rated 2800. https://codeforces.me/contest/10/problem/D
you're right! I have been upsolving 1900 rated problems and definitely feeling the difference between old and new problems.
When I start doing high rated problem then my level I first try the last page then second last . . . cause the last page problem are lot easier then first page I even see some 1400 rated last page problem which are easier then 1000 first page problem.
A second hand product is always lower priced
Even though I don't agree with you, the world needs more proverbs like this: proverbs that you can just drop from time to time and everyone will know what you're talking about.
Kindoff yeah. It's not necessarily a thing of skill (even tho the skill increased), like 8 years ago there were less people doing cf's and therefore the ratings were not really accurate (for our time). One would argue that generally the same ratio of "good" and "bad" people enter codeforces therefore the ratings should remain the same but i don't think so, nowadays codeforces is much more mainstream.
Don't know about others but I get worse every day
