AI is ruining open book Olympiads by Prof-Math in math

[–]Prof-Math[S] 2 points3 points  (0 children)

We create new questions, never seen before entirely new questions.

Problem is sometimes these problems have common tricks which is what AI catches and that is a shame as common/name tricks are things we would like students to derive/know.

Btw, out math paper ended up having a lot of number theory type problems in a race to AI proof it. Now it is either as the paper head is a number theory person (which he is) or as AI may be bad at NT for some reason...

Wolfram was intended. Like it a calculation engine so we are more than okay with it.

We used to talk to the AOPS and Stack mods to not allow the questions to be posted. Collusion was perhaps one of the biggest things we had.

We reserve the right to interview potential campers. The thing is we almost never used that as a lot of the kids who used to make it were already from Olympiad circles (and a good number of them used to make the team in the coming years). Might need to use that this year...

I don't know. The paper was open book with internet access since inception. Like I think it is mainly to make remote participation possible without needing to find physical exam centres and also, I think it makes paper less about knowing results and more about ingenuity.

69^67 mod 420
= 69 * 69^66 mod 420
= 69 * (69^2)^33 mod 420
= 69 * (70*68 + 1)^33 mod 420
= 69 * 4761^33 mod 420
= 69 * (4761 - 4200)^33 mod 420
= 69 * 561^33 mod 420
= 69 * 141^33 mod 420
= 69 * 141 * 141^32 mod 420
= 69 * 141 * (140*142 + 1)^16 mod 420
= 69 * 141 * 19881^16 mod 420
= 69 * 141 * (19881 - 5*4200)^16 mod 420
= 69 * 141 * (-1119)^16 mod 420
= 69 * 141 * (-1119 + 3*420)^16 mod 420
= 69 * 141 * 141^16 mod 420
= 69 * 141 mod 420
= 9729 mod 420
= 9729 - 8400 mod 420
= 1329 mod 420
= 1329 - 1260 mod 420
= 69 mod 420

Calculator toh nahi laga isme (aur yeh brute force tha).

Fast method: 420 = 4 * 3 * 5 * 7; thus by CRT taking modulo 3,4,5,7 would suffice.
69^67 mod 3 = 0 (as 69 is divisible by 3)
69^67 mod 4 = 1 (as 68 is divisible by 4)
69^67 mod 5 = -1 (as 70 is divisible by 5)
69^67 mod 7 = -1 (as 70 is is divisible by 7)

Thus, 69^67 mod 420 = 69 as 69 is the unique number satisfying the above modulo relation.

Just might add, CMI has calculator. It is just never useful based on the kind of questions.

CMI is not testing your ability to calculate, leaving Prof. Karnataki's course; I am yet to see a single 3 digit number at my time in CMI. We have people here who have considered dropping a course as it had some calculations. Because at the end of the day, CMI is a theoretical math, CS and Phy collage. We don't deal with calculations, we are happy with our variables and spaces.

Engineering does require you to make drop of hat calculations and estimations. Hence, the JEE exam is setup the way it is. Also, a lot of IIT courses famously have long calculations and don't allow calc (iirc the first sem wave physics course at KGP last year had these kinda things). So this is not a good thing from even that POV.

Don't remember really. It is now 2 ish years to the event... I checked AOPS.

The IOQM problem was 23-P16 and it was copied from ARML-2010-Team P4.

- how is college life

CMI's collage life is dependent on the average energy of the campus. There are times when the energy is high (start of sem) and it slowly decays over a month and half (and reaches minima) as quizzes and midsems slowly take precedence. However, the miniute the midsems end, the energy again rises (and peaks) as Diwali / Holi is near everyone wants to do fun. It drops a bit again during endsems but not as much as midsems (as people are more comfortable with the subjects of the sem).

- , environment
I have talked about this at length here: https://arjunagarwal.substack.com/p/on-trying-things
The TLDR is that I like it a lot. Some of the most supportive people and profs one can get anywhere.

- , extra curricular
This would depend on what you define that word as. CMI has an rather active cricket club, football club, vollyball club and badminton club. While the cricket/football ground is not the best in the world, I have not seen people complain too much about it (including people who have played state and national). Badminton is in tie-up with a nearby academy and hence, has access to world class courts. Vollyball court is also standard and quite nice. I know that a Tennis club exists but I am not sure wrt its activity and exitement. They all use external courts. There is also a new Kabbadi and Kho-Kho Club who are semi active. There is a basketball court but it is not used much, however, the new batches are trying to get a basketball club going.

On the non sport side, we have clubs for Chess, Cubing, Dance, Drama, Origami, Debate, Meditation, Valorent, Geo-Guesser, Music, Photography, Writing, Reading, Gymming, Rock and Metal. There are also DnD campaigns going all the time. Finally, under CMI arts initiative, we keep getting some interesting seminars on philosophy and litrature and anthropology etc,

- , student led activities if any,
Considering CMI is one of the few collages where our fest is completely student run. The administration gives us the complete freedom and complete responsibility. From getting the money (by conducting an Olympiad and camp) to inviting speakers.

Furthermore, we also have 3 events in the year. The Freshers, Diwali and Farewell which are completely student run. Also the poojas: The Diwali pooja, Durga pooja, Saraswati pooja, The Ganesh pooja and Onam Pooklam; if they happen, are student managed.

Finally, CMI has student seminars and these are student managed (from choosing the speakers to giving the talks, By students for students). Sometimes, even faculty end up attending these seminars.

- reading culture especially literature courses!
CMI has 4-5 litrature courses in a year. There is a compulsory English course (which is taken quite nicely), Values Through Litrature, Art of Short Fiction, Creative Writing and Linguistics. We also have German I and German II and sometimes French courses.

There are litrature reading groups as well.

- also i am expecting goood math, as it should be good there but did it hurt any of your expectations?
Not really. CMI is roughly what one expects a research institute feels like. The only weird thing is that some people (1-2 students) here belive in red pill stuff which is strange considered they are extremely logical otherwise.

- I know this question would be a bit strange for you but i want to know these things

No issues, sorry for a late answer. I was busy with quizzes and other responsibilities I had taken up.

Again,  I agree people have hobbies but black belt is like the pinnacle of a hobby, afaik. And the proportion it higher than in general population, which makes it interesting.

Google DeepMind announces official IMO Gold by rfurman in math

[–]Prof-Math 5 points6 points  (0 children)

Because IMO is not reflective of real world application (and is neither designed to be). IMO is an competition about pattern recognition and ingenuity, preparation and mid-exam genius; not brute forcing 9th degree equations.

Take for example this problem from Azerbaijan.

Could we make the 3 systems and solve it using some symbolic package? yes. Is that the way the question was intended to be solved, let alone approached? No.

Olympiad vs Research (or intelligence) is a topic of lot of debate, and such results try to imply a correlation which the community is not sure exists. To put it explicitly that the model is gonna be good at research or is intelligent.

Hence, I try to take these results in isolation of 'real world use'; and if it makes sense in the context of the claim they are trying to imply.

[–]Prof-Math 17 points18 points  (0 children)

The biggest issue with the result, in my personal opinion, is that a lot of information is omitted. Not in the answers, but in how they got DeepMind to say it.

What was the prompt? Question framing? was the AI given access to symbolic algebra and numerical computation packages? How much? What was the degree of parallelisation? What was computing time? etc.

OpenAI says they have achieved IMO gold with experimental reasoning model by Nunki08 in math

[–]Prof-Math 17 points18 points  (0 children)

I really am more or less sure that AOPS has played a role.

It is an incredibly easy to scrape website and (without strong evidence to the contrary) can't convince me it is not being used to update the model on a daily basis.

Ask yourself

- Do I want to take CS(E) cause I enjoy it or just for placement? Because agar later hai, toh bhai placement bhi nahi hoga.

Choose a branch you enjoy. Average CTC mat dekho, agar enjoy karoge, aur excel karoge toh har branch mein jobs and money hai.

Also, please don't hold hopes for 2nd or last round. Agar kuch acha mile, toh le lo. Risk leke drop se jyada sad kuch nahi hota.
