Math olympiad blog

Thanks Vipul, for your blog and providing all the info. Although I am not a math expert as you, I certainly value the importance of math. And Congrats to you for all the success you have earned!!! I have read about your adventures in mathematics from your blogs. Actually I am also trying to get into a good rank in rmo or inmo so that I can pursue my research career.

I am trying to complete Thrills and Challenges and I am also having arihant's maths olympiad as well as arthur engel's book. Eventually Prof. Subhashish will try to give Videos for full course here for you. I am also love mathematics just like you.

But my main concern on algebraic questions and trigonometric problems. Currently I am prepared for maths olympiad exam. I am also want to success Such like you I want to know few details about research in CMI n what is the criterion and all.

I hope u will reply. I have done my M. Sc in mathematics. Hi Vipul i am really impressed with you are International Mathematics Olympiad two time silver Medalists and your preparation techniques also good.

Hi, Thanx for sharing information good work. As a parent, you must have heard your kid say that he or she doesn't like math or math is a boring subject. This is mainly due to the old teaching methods that are still followed by the classroom teachers. Many times, the teachers are greatly responsible for the disinterest in students regarding math.

The importance of the subject in our life cannot be underestimated. However, many parents find it quite tough to instruct math to their children. In such cases, you must consider hiring a good private Math tutor in Bangalore who will help your child enjoy learning numbers. I like your post The post which had been shared is quite impressive and very well written.

Thanks for sharing. Much thanks for your useful information Science Olympiad Info. Experience shared is very informative.

Thanks for the insights on Mathematics Olympiad. Students will understand better with the information provided in the post. Olympiads are really helping in nurturing analytical and conceptual learning apart from the school syllabus.

Please keep on posting such useful and detailed posts with the latest trends and updates. I did a search on the topic and found most people will agree with your blog Indian Service Centre India. Great tips shared by you, I really like the way you convert your thoughts into this relevant word, maintaining the transparency of the content's logic.

Thank you for sharing this beneficial detail here among us. Keep writing.So, who is Stierlitz? This was a popular movie in Bulgaria in those days behind the Iron Curtain, when films were rare. I remember watching some TV series as a child. So, about the problem. A typical Russian one. The more techniques you know the worse. The first thing that occurred to me upon seeing it was the probabilistic approach.

Let me first present the problem. I used the translation given in [1]. Problem Prove that Stierlitz can send encryptions, each time choosing some characters to flip, such that when the Center receives these ciphers, it may unambiguously restore the original code. The problem can be reworded. Let be the space of all binary strings of length and consider the Hamming metric. That is, for any we denote as the number of bits in which and differ. I did some calculations, and as it turns out this number is quite large.

We substitute dot and dash by o and 1. Suppose the string Stielitz wants to transmit consists of zeroes If it is something else just flip appropriately some zeroes to ones and vice versa in the following lines. The first two strings Stierlitz transmits are. Note that this reveals to the Center the last two characters, in this particular case. Thus, consist of characters and differ at each position.

It means that one of them differs from in at least bits, hence the last two bits of the original string cannot differ from the corresponding bits of the first two encodings.

The next two strings Stierlitz sends are. The Center already knows that the real last two characters arehence the rest of the strings must differ from the original at exactly positions. The same argument as above yields the characters following the first ones elle fanning with the original.

Thus, the Center knows the last symbols. Stierlitz proceeds the same way, every pair of encodings reveals the another characters. The ninth funny safety moments for meetings tenth strings are. The Center already knows the last characters, hence the first symbols of these two strings differ at exactly bits from the original one.

So, the Center reveals additional bits and knows the last ones, in our case all zeroes. Now, look at transmitted string 1.

We see that it differs from the bits already known at positions. That is, no other differences can occur, hence the first bits of the original are exactly as in the string 1, in our case zeroes. The center knows the whole original string. In many cases, the probabilistic approach is a powerful weapon.If you are seriously interested in MIT, you probably think math and science are serious fun.

These are national and international competitions that prove beneficial in the long run. Olympiads can be seen as a platform for students of school level to showcase their skills and talent in their strongest subject. A rank in the Olympiad helps students explore their talent.

Questions asked in Olympiads are more conceptual and tricky which requires students to understand the topic well. This ultimately improves their routine class results. It helps students to test their understanding, level of knowledge and power of reasoning. It helps to cultivate the analytical and logical thinking in the students which is quite useful for any competitive exam.

Awards and recognitions is another prominent advantage you get by taking Olympiad exams. Digital is the new way of studying. Other than the up-to-date syllabus and questions, the digital study has grown tremendously across the world due to a number of reasons. At Speedlabs. The students who are preparing for any of the Olympiad need to follow the proper study plan by preparing a complete strategy for every particular subject.

Students reading this in future years are advised, as always, that such commentaries are normally more valuable after attempting and digesting the problem yourself first. The paper can be found in its original format here. An exhaustive search is impractical and uninteresting. However, beyond that, we would also like to find integers N which we are convinced have this property without needing to explicitly decompose them into the desired sum format.

We need an even number of odd numbers to end up with an even sum. Probably the algebraically neatest way is to set up such a sum symmetrically as:. So, we seek integers N which can be written as 2nm, where m is an even number, in as many ways as possible.

Note that if we have an integer N which can be factorised as a product of two distinct even numbers we are forced to take the larger as 2n, and the smaller as m, since we require 2n-k to be strictly positive. It is useful to remember that is M can be factorised into primes as then its factors can be described as the set:.

In particular, the number of such factors isindependently of the choice of the primes. We could take to be some permutation of 11or 5,1or 3,2or 2,1,1which give the following valid M:. The other success rates have similar constraints, but the multiples are smaller.

So we need at least twenty games. But can we do this in twenty games? This would require Arun to win 3 out of the first 10, and 14 out of the first 20 or the exact oppositeand after some head-scratching, this is impossible, since it would require winning eleven out of the ten games between these observations.

This is a nice observation, and we now know the answer must be at least thirty. Given that we have made some nifty, rigorous deductions already, one might speculate that this is the true answer. To verify this, we just have to give a construction, and there are a number of ways to achieve this, for example such that Arun wins. To get full credit, almost any justification that a construction exists for 30 games would be fine — but one must be given.

If nothing else, such experiments may well lead to a conjecture of the general form of the answer. This corner is for aspirants of Mathematical Olympiads.
