    Only limited by your imagination and hard work, but based on my experience, I'd say 1800-1900 is a reasonable goal to have.

      Please, predict for me too, assuming that I will spend 3 hours a day in average without big breaks.

        I don't think that's the right question to ask, I was merely suggesting a reasonable goal. Depends a lot on how fast you learn and other things, but it won't be a surprise if your rating stays within [1800, 2400]. You might want to read this blog I wrote about my perspective on learning.

    Consistent practice, plus lots of perseverance and thinking time. And once you solve a problem, try to internalize the steps you took so that you can solve other problems in a similar manner. Maybe you'd like to read this blog.

            First things first, I don't need to join any IIT to speak facts.

            How would you know if I am from any IIT or not ? Don't worry this ain't my real account, This is one of my alts. I created this in 8th standard.

            I think the truth was bitter for you, apparently you are not from any top IIT ig.

              This flame war is why I didn't want to respond to any IIT related comments, but decided to respond in a light-hearted manner just in case.

                Neither. I just stated the truth. That is it. But he judged me.

                If that is sarcasm, then my comment ought to be treated as "sarcasm" only.

                I have a strong conviction that you are not flummoxed, you are just trying to defend a judgy and absurd comment by using that stereotypical joke.

                  "Thinking is difficult that is why most people judge".

                  Why the hell did he ask for my real account ? I ain't a grandmaster, that's it. I looked up to him, but now I have nothing but a strong grudge against him, and all of y'all who are unnecessarily downvoting.

                  Where did I go wrong ? He judged me, and I judged him back.

                  I am 15 and I just witnessed the fatuousness of adults. I also experienced partiality. You guys really need to work on your communication skills. If you are right, prove it. Don't act like a coward.

                  "You need a specific rating range to make alt accounts and trolling" ? This is ridiculous. Indeed your communication skills are....

                  Idgaf about the downvotes, again this ain't my real account.

                  Wikipedia : Ain't is commonly used by many speakers in oral and informal settings, especially in certain regions and dialects.

                  I acknowledge that it is not a part of standard English. But hey you guys are making fun of basic english only. You want me to write formally ? That would be an overkill.

                  If someone's language defines their IQ for you, then You should get yourself checked.

                  "It ain't rocket science!" Musk said about his proposed Twitter deal.

                  You are implying that you are smarter than Elon Musk ? That doesn't make sense tbh.

                  You presuppose that Elon Musk is smart lmfao. The only flattering attribute he possesses is being an edgelord.

                  I sincerely hope that you're a troll and all the comments you have made so far have been completely ironic parodies of the musings of a biblically obnoxious cretin, whose norminess oozes out of every orifice of his body.

                  cretin ? mind your language, I did not abuse you.

                  Obnoxious ? do you even know the meaning of these words ? Obnoxious means unpleasant. A sarcastic comment can be unpleasant for some people.

                  I think you are googling ["word" synonyms] and using the most outdated words to look cool ? But still I am able to understand every bit of it. I can even speak Hindi if you want. (Don't search for synonyms)

                  No, I am not a troll, I will take that apology.

                  I intend any and all offense this statement may cause, but if you think any of the words I used would need to be googled by someone, then you either:

                  • Have received an extremely poor English education.
                  • Possess the linguistic skills of a 3 year old.

                  But then again, that's par for the course as far as people who use the words "y'all" and "ain't" are concerned.

                  On a final note, I would like to congratulate you on proving the inaccuracy in my usage of the word "obnoxious". Would it be too self-indulgent to point out, once more, that this shocking proof is pretty much expected from a person who uses the words "y'all" and "ain't"?

                  Edit: I've just had a look at your rating graph, and I'm sorry, but I cannot continue arguing with you and risk being labelled as ableist.

                  "Have received an extremely poor English education."

                  Maybe you are right. I come from Bihar and I have been studying on my own without any tuition. I also had a serious spinal cord injury (anterior wedging of the L1 and T1 vertebrae) in class 9 and as a repercussion, I did not attend school after that. I wrote my matriculation papers though.

                  "Rating Graph"

                  This is not my real account. I created this account in the 8th standard. I am currently in 11th standard. I just cleared 10th. But I must say that I am rated higher than you in my real account.

        Depends on your definition of solving. I define solving as not having to look at any hints/editorials while attempting the problem. Just out of the comfort zone for me is when I can only solve about 30%-50% of the problems I try at a certain rating level, given enough time. It varies a lot from person to person and it usually helps to figure out your limits on your own.

    Depends a lot from person to person, one really has to experiment to understand what works the best for them. I personally prefer reading books and solving problems over watching videos, because there is more deep content and you can play around with ideas much more easily with them. I am not aware of any sheets for training that work for everyone or any specific routine that works for everyone, you might want to read other blogs about people's personal experiences. If you really want a "track" laid out for you, multiple blogs about how to practice are here.

    Don't interact with cheaters if it affects you that much.

    I won't say frequently, but sometimes. In a job, it depends on what kind of work you're doing. For instance, if your job involves implementing anything close to a programming language, you will find trees in the form of abstract syntax trees, and graph theory (flow graphs, dominator tree etc.) is quite ubiquitous in that field. However, in any job, you should be able to apply critical thinking that you can develop during competitive programming.

  1. PyTorch or TF/Keras?

  • »

    11 months ago, # ^ |
      Vote: I like it +5 Vote: I do not like it
    1. Depends a lot — based on my experience in uni, TF/Keras is faster to work with (less setup time), but PyTorch makes it easier to be flexible. I'd prefer the former if I had to come up with something quick and dirty, but the latter if I want to do something much more seriously over a longer period of time.
    2. Read a lot of well-written books (famously well-written books can be found for every topic if you search for them on MSE or MO). And make it a habit to read Wikipedia pages on math and follow links to the references, without being afraid of reading papers, googling stuff along the way (probably the best habits you can develop if you want to learn new theory). The reason I suggest Wikipedia is that it gives a bird's-eye view of the topic and the connections to other topics, and it's a great starting point to understand what kind of theory exists in the first place.

      Doesn't research interest you? Do you see yourself in academia in the future?

        For me at the moment, research is interesting, and so is quant research. I am somewhat disillusioned by academia for multiple reasons that I have seen my friends who do research come across (pay to publish, publish or perish, slow feedback cycle, reviewing politics even in double blind reviews, ridiculous paper rejections or evil reviewing in general, low pay, credit-stealing, constant fear of someone else beating you to your results, alienation due to getting stuck in a niche, and what not), and would not be interested in pursuing it for the foreseeable future unless something miraculous happens.

            From what I know about them (everyone's experience seems to be different, so take this with a grain of salt), they don't seem much different from a normal job that involves a fair amount of research, and there's much more anonymity (read: lack of recognition), and structured work hours etc., which makes it quite different from academia in that sense. The objective function changes drastically too (going from publishing papers and going on a pursuit of knowledge to using research in applications and make a profit out of it). Sounds interesting but idk really.

How do you approach reading books, specifically mathematics, and how you grasp the intuition behind a rigor based book?

  • »

    11 months ago, # ^ |
      Vote: I like it +13 Vote: I do not like it

    When reading a book or a paper, I try to read it with an open mind in all generality, and keep all my doubts for the end, while actively trying to draw parallels from what I already know and have intuition about. Thinking about examples helps internalize the ideas presented in the book/paper.

    It is quite important to re-read the content in case it is technical, because authors often write books/papers in multiple iterations, adding some more detail at various parts of the text, and unwrapping those iterations leads to different insights that a single reading might not be able to uncover.

    Also, refer to alternative resources in case something is unclear. Try to not be stuck at one point, because it will make you lose motivation rapidly.

    I've also written a bit on this topic in this blog, under the heading "How learning can look like for you" — maybe it'll help too.

    This and this are some well-documented ways on how to approach reading books and papers, that I concur with.

    Consciously try to get everything right on the first go. For instance, try proving that your code is correct with invariants. For stress testing, I don't really do a lot of things during contests, just random max tests and enumerating all small tests.

I am confused usually whether to write a recursive code or iterative code. Though recursive code is simpler to code than iterative(book keeping by our own stack) it some times give memory error. (recursion stack exceeded (or) memory limit exceeded sometimes). Although I think there is no recursion depth limit in C++(but there is recrsion memory size limit), but there is a recursion(default) depth limit in python. Can you say some valuable tips so that I can figure out whether If I recursively code, I might get an error which helps me while solving problems? Thanks you.

      Vote: I like it 0 Vote: I do not like it

    I find it hard to list out everything I did to reach the "level" I am at right now, assuming you're asking about intellectual development. I started doing higher math quite early on out of my own volition, without a teacher or a guide as such, so it might be hard to relate to my experience. I did read a lot of math books, and referred to Wikipedia a lot. This was before I got to know about Olympiads, and I believe a lot of my mental growth was positively impacted by doing math, physics and related Olympiads. I believe you can learn stuff from any resource — you could imagine an ignorant 10 year old typing "good free maths books" into a search engine without knowing what he is getting into, and that worked out for me just fine.

    Regarding specific books, you might want to browse for specific recommendations in places where there are people better read than me, like math stack exchange for math, or AoPS for olympiads. I believe that the one thing that helped me a lot was that I liked reading books a lot, because it was fun to look at how different people explained the same thing. In that sense, it would be unfair to attribute stuff to just a few resources that I used. A specific resource I can't recommend enough for academic pursuits is Wikipedia — don't listen to teachers parroting the same "Wikipedia is evil" narrative; the math and science side of Wikipedia (and the whole site in general) are too strict to allow misinformation to pass, and if you really don't trust Wikipedia, read the references.

Can you give us guidance for building mathematical intuition and problem-solving skills? It is said that "Those who are good at maths have more clear intuition and logical reasoning for problem-solving." So if anyone wants to build their math skills, logical reasoning and intuition from scratch, what should he do?

Please suggest some beginner-friendly resources where we can start and go to a decent level. I did not give much importance to maths at our school level. But recently, I think I have become interested in mathematical problem solving (Olympiad Style Problems) and competitive programming. I like to solve problems only with pen and paper. I don't know where to start as a beginner. Please help me if you can. Can you suggest books, articles and video content etc.?

    To build intuition about correct things, you should first know what constitutes a correct thing, and how you can be sure that the thing is correct. This is a nice book on proofs, and understanding why things work in the book should be a nice exercise.

    Now that you know what a proof is, and what correctness is, you are in the right frame of mind to build intuition (wrong intuition is worse than no intuition). Now try to solve problems (from any source you like), starting from easy to hard. Document the process (either mentally or with pen and paper). Ask yourself questions like did you guess the solution and prove its correctness, or did you build on it step by step? Both approaches are valid if you can show they're correct, intuition is part of what will help you make these kinds of choices fast. There is no good way to build intuition other than to have an idea of why things work, and that comes only from interacting with similar things. At this point, I believe it is a good idea to read this blog.

    I have a few books that I started out with, and I feel that they're somewhat decent. They may or may not work for you, but they were quite popular in the math olympiad community when I did MO. Here's the list of books, in the order that I remember starting doing them (or at least the order that I remember):

    • Challenge and Thrill of Pre-College Mathematics
    • Mathematical Circles: Russian Experience
    • Problem Primer for the Olympiad
    • The Art and Craft of Problem Solving
    • Problem Solving Strategies
    • Solving Mathematical Problems: A Personal Perspective
    • How to Solve It

    There are a ton of other advanced books, but I believe those will probably be overwhelming if not done in the right order, unless you have a voracious appetite for reading and solving problems. I omitted some advanced books that I started alongside these books for the same reason. If you run out of problems, you might want to browse this website (don't navigate through the courses, but the forums for problems and the wikis for resources). For more bite-sized problems and informational content, you might want to refer to this website — it has a great collection of interesting problems with multiple solutions.

      Thanks a lot. Your guidance is crystal clear.

      After reading this book, you said to practice easy to hard problems from any source I like. But I don't know about the sources much.

      Can you please provide me with some sources for practising? Like, practising from the sources and being playful with the resources and problems will guide me further.
