codeforces difficulty level

I have just reviewed the present histogram of the difficulty ratings using the filtering feature. I was the first person to solve it there in-contest and I was thinking "wtf why did nobody solve this yet". Also, i think it's some kind of weighted average from the rating of all the people that solved the problem on-contest, there is no direct correlation between score and number of solutions if you scroll through a bunch of examples on the problemset. Does it take into account unofficial participation during contest? The reason for this discrepancy appears to be that the difficulty rating is a static number that is not updated dynamically when more solutions are accepted during the practice phase. The only programming contests Web 2.0 platform, 2020-2021 ICPC, NERC, Southern and Volga Russian Regional Contest (Online Mirror, ICPC Rules), Codeforces WatchR: 10K+ downloads on Google Play, Technocup 2021 Elimination Round 3 and Round #692 (Div. I want to see the rating in problem, not in problemset. Is it possible to sort problems in favourites section by their difficulties ? I'm asking because the ones for the two previous contests (here and here) have not been updated. Difficulty Level: 3 The difficulty should be visible also on the problem page like the tags. Programming competitions and contests, programming community. I can think of more than one model which can be used to get such approximation, so I'm curious what exactly stays behind it. I am actually able to see the ratings of problems even after disabling it. ( Because you may have selected the task from a contest page, not from the problemset page ), This is a great feauture! "Monsters and Potions" has rating 2500 [don't read if you are planning to solve Southern Subregional! The difficulty level of these questions is similar to that of Codeforces Div2B, Div2C. I usually come across them when I see them see in the recent actions section when someone comments on those blog posts. 1 + Div. That explains why the difficulty rating is that high. Currently, if I'm logged in and enter a difficulty in the "Filter Problems" widget, it only lists problems that I've already solved. This is useful if the same handle is used across multiple sites e.g. For users satisfying this condition. It actually depends on what company you are targetting. I didn't understand it on the first place. I want to hide the problem tags and filter problems with difficulty. Another top team finds another mid-level problem and solves it, because it is easy for this team too. Programming competitions and contests, programming community. Basically, I suspect there are a couple of bugs in the rating calculation. https://en.m.wikipedia.org/wiki/Elo_rating_system#Theory. My Review about Scaler academy. Of course, simplest among them are even simpler than easiest LeetCode questions. To all my Indian juniours and experienced professionals, Never join Scaler Academy(Interviewbit). Checkout how the rating is calculated for a better idea of why this happens. I feel like it's unfair on CodeForces, that there are anti-Java test cases - for sorting and HashMaps. A little addon Can you guys also add Hide Solved problems in all searches? In order to list unsolved problems when filtering by difficulty, I need to check the option "Show tags for unsolved problems". under the "filter problems" box there is a "settings" box. The only programming contests Web 2.0 platform, 2020-2021 ICPC, NERC, Southern and Volga Russian Regional Contest (Online Mirror, ICPC Rules), Codeforces WatchR: 10K+ downloads on Google Play, Technocup 2021 Elimination Round 3 and Round #692 (Div. Codeforces Round 692 (Div. ... Group Difficulty Range Group Size A. If it is in general then it should be changed to only official solutions. Small question: is there any bias in difficulty for D and E problems just because they're 4th and 5th among all the contest problems? Difficulty Level: 5 I think it would be great! Difficulty Level: 2 I still have to press F5 continuously. Ladder Name: 31 - 2100 <= Codeforces Rating <= 2199 (Extra) Description: Extra problems for users satisfying this condition: 2100 <= Codeforces Rating <= 2199 (Extra). Check the box "Show tags for unsolved problems". Is it some kind of bug ? It would be nice if it will filter according to user rating by default. I went over a few recent rounds and checked what performance you are going to get if you are only solving problems with the difficulty <=1200. 2) and Technocup 2021 — Elimination Round 3, A new cf update that you may haven't notice, Invitation to CodeChef December Cook-Off 2020. Codeforces. I have a small suggestion. Really nice feature, I love it a lot. Also, in problemset, how it has been calculated ? Third top team finds another mid-level problem and solves it. The pop-up feature of judgement verdicts is not working in my browser. Dude, if you know the tag whats the point of hiding it! With that being said, I'm curious why it sometimes takes quite a long time to add problem difficulties for some contests. I really want this type of thing. so I want to use this problem rating instead of solved count in codeforces API! Approximately this means that if the rating of the problem is equal to yours, then on a typical round you would solve the problem with a probability of 0.5. That would be great. Can we have them in intervals of 10, at least? I believe that there are many other people who have been and will be benefitted by the tutorials available on codeforces. uncheck it and no tags will be shown. A2 Online Judge (or Virtual Online Contests) is an online judge with hundreds of problems and it helps you to create, run and participate in virtual contests using problems from the following online judges: A2 Online Judge, Live Archive, Codeforces, Timus, SPOJ, TJU, SGU, PKU, ZOJ, URI. Help needed from participants with rating up to 1500, Help me to find out the right approach of this code, The 'science' of training in competitive programming, https://codeforces.com/problemset/page/47, https://codeforces.com/problemset/problem/26/A. ... and what is the difficulty level for A,B etc in educational codeforces contest Ladder Name: 13 - 1400 <= Codeforces Rating <= 1499 Description. Meet a small innovation on Codeforces — difficulties of problems (and at the same time a new widget filtering problems in the archive). : ). Thanks for a new feature — looks interesting! Codeforces. UPD: Добавил в API опциональное поле rating к объекту Problem. UPD 1: Have you already noticed new pop-ups about judgment verdicts of your submissions? LeetCode is great for preparing for interviews. Isn't it better to disable this feature for ICPC contests? Please give an option to just see problem rating in tags instead of showing both rating and topics in tags. Yes, it is much simpler. For all the problems of the archive, I’ve calculated the difficulties in the scale of the rating of participants. He probably submitted his solution earlier than you. would have had a probability 0.5 to solve it during a "typical" 2h individual CF contest, or during a "typical" 5h ACM team contest? I think it could be lower. i hope in the future add categories by (A,B,C). Difficulty Level: 5 See how have you performed, what you need to do now, personalised contests made just for you, outstanding graphics giving you a gaming feel in competitive coding. Also, are there any pitfalls/issues that we are already aware of? One question: consider a problem from a 5h ACM contest; if I have a rating 2500 and the problem has 2500, does it mean that I (my team?) I think this problem have a high difficulty. Ladder Name: 11 - Codeforces Rating < 1300 Description: For beginners, unrated users or users with Codeforces Rating < 1300. Take a look at contests 26-28. https://codeforces.com/problemset/page/47. I think the levels of problems are unfair. MikeMirzayanov, Great feature ! no actually the difference in time probably one minute and the the rating difference is much big +65 and +24 the actual score is showing 474 and 472 but rating difference is very large. 2 Only) There have been some blog posts that have tried to collect the available tutorials but they include only a handful of these. Realy good development.We can learn about the difficult and we don't need to search question anymore. The main reason I created this, is because the a2oj ladders are pretty outdated (all from 4-5 year old contests). 1, Div. Thanks :). Would it be possible to add an option to view problem rating within the statement of the problem? The main reason I created this, is because the a2oj ladders are pretty outdated (all from 4-5 year old contests). Even more specific example, take a look at https://codeforces.com/problemset/problem/26/A with rating 2400. I've included a Solved column, to easily keep track for those who want to practice all the questions. Submission time matters too. Note that the start time is unusual.. Series of Educational Rounds continue being held as Harbour.Space University initiative! 1100-1200 415 C. 1300-1400 429 D. 1500-1600 497 E. 1700-1800 503 F. 1900-2000 442 G. 2100-2200 447 H. 2300-2400 473 I.

Problems on TopCoder are very balanced, so 250/500/1000 are very similar in difficulty (of course there are exceptions) and this is very important for rating. pop-ups about judgment verdicts of our submissions have stopped working (since the DDOS attack I guess). I use codeforces API for automatically select random problem that nobody in my problem solving group solved. I have one suggestion or request.. great feature! I love A2OJ a lot right now, so it's just a suggestion. Approximately this means that if the rating of the problem is equal to yours, then on a typical round you would solve the problem with a probability of 0.5. I tried with a bunch of tags to list all related problems but the result had no problems. But, you can see the rating of the problem only if you select it from the problemset... Would it be possible to see at when you are direct on the problem / task page? While I do understand where the formula came from, I feel that the definition of it being the probability that one would solve it in contest isn't really precise; maybe it would be something more like the probability that one would solve it in a contest with full feedback? Main ... Water Level . 1A(Theatre Square)'s difficulty is 1300? Why not add the difficulty in the tag? Correct me if I'm wrong. Codeforces cf/ no prefix: cf/tourist petr: Codechef cc/ cc/mugurelionut: Spoj sp/ sp/xilinx: You can apply multiple prefixes to same handle. I think that you can test this formula in several contests. Can we have something like similar problems suggestion for each problem, which will be decided by votes ? Codeforces. UPD: (API update) Optional field rating has been added to the object Problem in API. If I may suggest, it might be a good idea to add a parameter for rating deviation, as in the Glicko rating system. Thats the best thing Codeforces has ever done, now there is no need of SPOJ to practice specific types of problem. 2) Editorial. It was a cool update. For beginners, unrated users or users with Codeforces Rating < 1300. Congratulations to Codeforces team for this excellent job. Also, since it had been a long time, it is possible to see some awkward difficulties on old problems, because the ratings and some ideas have been changed. Edit: I thought I should give an example. For instance, problem D may have 2500 instead of real 1800 just because problem C from its contest is a long implementation problem and participants had not enough time after it to solve D. Thank you for this system, but, unfortunately, sometimes rating of tasks very strange and has big error. I used 'solved count' for judging problem difficulty. 500-1000 392 B. (It is easy problem i think). Innovations always going on. Hello Codeforces! One minute matters, especially for A and B considering there are thousands of users. The example threshold levels were updated based on the histogram data. Help needed from participants with rating up to 1500, Help me to find out the right approach of this code, The 'science' of training in competitive programming.

If you don't think it's worth doing, that's fine. So if I search for problem on binary-search and geometry, the result should contain all the problems which have at least one of these tags, right? That problem is rather 1500. But it might be quite helpful if this feature of filtering problem is added... Just a personal point of view.. Can somebody explain why 1071C - Triple Flips has 2900 rating and 1071D - Familiar Operations has 2700, despite the fact that the first was solved by 40 persons, while the second by 20 during the contest? CodeForces-Ladders. I want to see the difficulty of problems, but don't see tags. Is the difficulty rating of a problem accessible via Codeforces API? ahmed_aly any consideration to add this to the CF ladders on A2OJ? It's really useful change, as always. How will you calculate problem rating before contest ? In some problem why i get less rating than a friend of mine for same problem submission and the problem is correct in one chance? Any plans on using this to have a dynamic score on the contest? The accuracy of those ratings might be improved by taking the AC ratios into consideration. Codeforces Contests. In the blog which MikeMirzayanov introduced this helpful scale, he commented that the difficulty rating was computed based on the contestant rating during the contest. This is what happened on that Southern Subregional. Felt like I was reading a problem statement. Is it just me or others are facing the same issue? The current difficulty measure scale of Div2C — 4, Div2D — 5, Div2E — 6, isn't always that accurate. Just kidding, I don't even have a jacuzzi. Now I can try to solve problems whose difficulties is around my current ratings so as to improve myself more efficiently. Because sometimes I see the problem and look at its [high]rating, I leave the problem without even reading the statement, I believe that this stifles the growth to some extent. I usually struggle with finding problems in a specific field, like solely segment tree or abusing STL data structures as they all share the tag "data structures". Difficulty Level: 2 It would be great if there was an option to filter by difficulty without having to show tags for unsolved problems, as these can give hints which spoil the problem. After playing around with it a bit, I've found that the probabilities it gives seem more extreme (closer to 0 or 1; farther from 0.5) than I would believe once you consider that Codeforces contests only have partial feedback (like pretest and systest phase). During contests, I don't have to stare at the submissions to see whether I passed the pretests anymore! Great feature by the way, now I can tell that the problems I solve are too easy ;-; proud to be a part of such a great polygon. This would help while upsolving a particular contest as opposed to isolated problems, great feature !! Weaker teams follow them. It should make sense that problems of future contests belong to the aforementioned groups as follows. Right now, it seems to only be the problemset page, which makes it hard to find for the rating of a particular problem (I guess one workaround right now is try to make a mashup). Popups go from the internals of the judging server directly to browsers bypassing the database. I know it's a lot of work but maybe the community can help somehow by proposing the available tutorial blog posts to be added to the section.

For convenient search of problems in the archive, you can now use a special widget: With it, you can find not only problems that have all the chosen tags, but also which have at least one tag from the list. Nice feature, but... it probably looks mainly on number of users who solved a problem. Top teams discover it, say "LOL why nobody solved it" and solve it. Since this is a quite old contest, a lot of participants are now Candidate Masters or higher when the difficulty rating was introduced. Something like 10% percentile of rating can say more in this case — if a noob team solves it, everybody can too, they just didn't try it on the contest. - ldfdev/CodeForces-Div2-Problems Virtual contests should be taken into account too? i would suggest to show difficulties in problems statement beneath the problem tags , Thank you MikeMirzayanov.

At least its algorithmic part. — same non-trivial problem will often be much more solvable in 3h round compared to 2h round) and how rating inflation is handled (I guess for contests from 2010-2012 the score that you get from those ratings will be somewhat misleading because back then even 2200+ was a big deal — but I didn't go through old problems and their ratings thoughtfully to see if there is anything suspicious). Please, add also difficulty of the problem to the problem page. As I am not on a great level in terms of my ratings, there are many topics that I don't know of like segment tree beats, Berlekamp-Massey and so on. I have done both and this is coming from my own experience. The present 4721 problems in the problem set can be clustered into the following 12 groups with respect to their associated difficulty ratings. I should have written it in the main blog not under your comment, sorry again. While practicing, I was wondering if I can sort the problems in order of their difficulty level.

Like tags, it gives the extra information that can make you think a certain way/alter the problem solving process in a way that could be undesirable. CodeForces is great for competitive coding. Perhaps a staircase-wise upper-bound such as the following is sufficient to regulate the problem difficulties within the same contest: RE: a problem with much less "present" accepted solutions has lower difficulty rating. If you can add a feature to disable the problem ratings as we have for tags, it will be greatly helpful. So, this maybe the right place. Is it also possible to show the rating of the problem in the problem page? Also, there are a lot of tutorials on common topics but they way they have been explained in codeforces blog make them a lot more practical and helpful than other resources or tutorials on the internet like I would never have known that ternary search can be coded in a way similar to the binary search as explained here and also the blogs on maths topics like the mobius function and blog posts on geometry and other stuff. Difficulty rating is calculated according to the people who solved the problem during the contest. For example, it's been more than 2 weeks since Codeforces Round #599 but none of the problems is updated yet. But the problem is they are buried somewhere in the thousands of blog posts already on codeforces. And, in general, if your rating is ri, and the problem rating is rj, then the problem during the round can be solved approximately with probability: For example, if the rating of a problem is less than yours by 200, then the expected probability of solving the problem is 0.75. P.S. If you were to rate some IOI problems by CodeForces difficulty rating scheme, what would be the average difficulty level … You can read the details about the cooperation between Harbour.Space University and Codeforces in the blog post.. Could you please share code used to calculate this rating? Will there be such things for sgu problems too? Either it's a div2 contest with all ratings > 1800, or within a round where a problem with much less solves gets a lower rating than a problem with only one or two solves. 4.8K views. So, it would be amazing if a separate section can be created on top for the tutorials that are available on codeforces in which one can see the topics and the tutorial blog posts on them that are available on codeforces. Thank you for the great feature, MikeMirzayanov! Though if you have just learned a new technique or want to practice a given topic, then tags can be useful. I want to see rating but not topics.. Also it would be nice if difficulty can be viewed in contest's problems page to see the difficulty of all contest problems without having to check each problem separately. Reminds me of CERC 2014 where problem L was solved by 3 teams. Codeforces is already a more competitive programming site than topcoder. Company wise list, focus on code readability rather than giving a, b ,c to variable names. It wasn't super easy, but something like the first or second mid-level problem and the organisers said they were disappointed so few teams solved it. Contribute to AhmedRaafat14/CodeForces-Div.2A development by creating an account on GitHub. As a learner, you can improve your programming skills by participating in contests with varying levels of difficulty.
