End CC Long Challenges

But codeforces arranges so many contests in a month with so many problems, and Codechef needs only 7-8 problems for long(each month), if I am right ?? Then also, it is hard ? :face_with_monocle:

Lol. But if CF contests were made ioi style with 6 hours contest duration, 100-200(the figure might be wrong!) pple would get rank 1. So, comparing it to the 10 long days of contest, you could really understand the difficulty involved in making befitting problems…

100-200 can never get rank-1 if we use codeforces ranking system, even in codechef short contests, 100-200 ppl will never get rank-1 as everybody takes different time to solve problems.

Yes, in ioi system , its possible!!

The only thing required is :- Long Problems need to be hard. I get it as we have 10 days, so when setters are not able to find hard enough problems for a 10-days contest, they put math problems .

I have no problem with math qns, it boosts score.

the thing I hate is when the question starts with “you have given a tree of N nodes blah blah blah…”
and the solution come to be 2-3 line formula…

You mean SJ1 problem from April Long ?

I personally like math problems as much as I like problems requiring only DSA. I really don’t understand the sentiment behind (by @syntaxhacker)

“questions based on observations and pattern findings instead of algorithms and ds”

How can you separate ds & algorithm from math is beyond my brain can comprehend. My guess is that you want problems that require nothing but knowing already discovered and well-known algorithms you can find in sites and solve without using your brain. If you lack the ability or passion to “observe” and “find patterns” and create your own algorithms then you’re in it just for jobs. Here’s an idea for your little brain: Someone had to “observe” & “find patterns” to come up with quicksort which to you may be an algorithm but is actually math & observation. Don’t try to classify DSA as not-math just because you suck at real math and got the idea that you are good at math simply because you can copy some math-stuffs which are trivialised to the point that they are not considered as “math” to you.

You are acting as if pure mathematical problems are never given on CC or any online platform.

If you are still in doubt, try and tell what DS and Algo are used along with Math in this - COMPEXP Problem - CodeChef

Here’s an idea for your little brain:

Not only are you giving an entire bullshit argument to the discussion but also flaming. I guess the one with “little” brain is someone else. :slight_smile:

Don’t try to classify DSA as not-math just because you suck at real math

From the discussion, its pretty clear that their real unrest lies in the PhD or research paper math given in long instead of DS+ Algo questions. For PhD math it becomes a big googling game for most peeps.

Then get some perspective first before posting.

90% people pariticipating in long challenges weren’t preparing for icpc or ioi or becoming any computer scientists for putting up such math questions .

most beginners dont have much math based observation . the goal of the long challenges is to help for us to learn new algos and use them differntly to solve the questions .so if we does oberserving for that silly pattern writing in books for days and realise how dumb we are when we find the actual answer or formulae and cry how much time we wasted for that when we will be able to do other problems based on algorithms and ds which are actually useful in real world problems instead stuck at the very first problem .
@faded4k
Lastly , if you want math based and love so much math problems just do project euler problems Or try cracking np hard problems and stick with them .

Yep. I’m the one with the “little” brain. Also I thought flaming a bit was okay since the entire sentiment behind this thread is flaming against math by people who thought they were cool at math but suddenly got their dreams shattered :stuck_out_tongue:

Well then, get your perspective right and stop spamming. :slight_smile:

so just stop caring about the post when you just consider just yourself as one who is giving the contest. there are beginners as well experts giving the contest which you should keep in mind . when preparing long challenges imagine if people who were new to this cp ( who joined computer science or just started cp ) stuff and just see math based question involving just the pattern findings as the very first qn which considered as the easy problem will give up on doing cp as they find it hard and find no usage of algorithms in that find no interest in solving that just wasting their time .

More knowledge in TCS questions , oh the Irony is true! :laughing:

Yup, I have and I procrastinate as well. I am sorry . :frowning:

This is my view : -
Even codeforces support beginners, they make most of the Div-2-A problems in such a manner, that anybody who knows programming can solve it . Because I remember, even when I was a beginner , I was able to solve Div-2-A problems :slight_smile:

So that much support any website can give to beginners to encourage them :slight_smile:

Hey guys, please don’t rating-shame anyone. Everyone deserves respect and basic courtesy in-spite of their ratings on Codechef :slight_smile:

Thank you so much for pointing this out,Its really more of a pattern finding or some formula developing contest now.

Its more of an observation based contest now.

I don’t remember when I used good data-structure, I’m really stuck on hash-maps and sets/multisets.

  1. “90% people pariticipating in long challenges weren’t preparing for icpc or ioi or becoming any computer scientists”
    where did you got such statistic? actually I think most people is preparing for contest similar to ICPC, IOI, or maybe preparing for coding interviews (where maths is also necessary) and most of them are interested in computer science.

  2. “the goal of the long challenges is to help for us to learn new algos”
    In part, but the number of algorigthms is limited. I think a coder of your level should focus more on problem solving skills (math helps a lot here) rather than on learning advanced stuff. Also ad hoc problems that doesn’t require any knowledge to be solved are the most beautiful (skill >> knowledge).

  3. “so if we does oberserving for that silly pattern writing in books for days”
    nature is made of patterns, ergo trying to find its patterns is silly? again if you are stucked for days is because lacking of skills, and solving it will benefit your problem solving skills. Also we should not discuss/spoil the problems during contest.

  4. " which are actually useful in real world problems instead stuck at the very first problem"
    if you get stuck in the first problem, go to the second! maths by itself is useful in real world problems. If you want to face real world problems you should try going to research (although to do research you should be able to solve the first question).

  5. " if you want math based and love so much math problems just do project euler problems Or try cracking np hard problems and stick with them"
    Yes I like maths (like any good competitive programmer). I’m not trying to solve P=?NP I’m more into graphs, game theory, topology

  6. “From next month not gonna participate in codechef long contests”
    yeah, long challenges are only for brave coders :slight_smile:

@alei I wanted to tell you that most of your contests(Long(May,July,August,March) ) are awesome :slight_smile: (Its ok we can deal with few exceptions some times)

And those problems helped us a great deal in improving our skills :slight_smile:
