Here is the full, detailed solution breakdown for the 6th problem from the Mathlete Sprint!

We wanted to get this out to you guys quickly so you can cross-check your workings and see where your steps lined up. The goal with these sprint problems isn't just about finding a final number, it's about the logic and seeing how cleanly you can navigate the core constraints under a bit of pressure.

Take a look through the steps and let us know how you handled it. Did you spot the shortcut right away, or did you take a longer, more brute-force route to get to the answer? If you ended up finding a completely different elegant way to solve it, definitely drop it in the chat below, we'd love to see how your brain worked through it.

A special shoutout to u/Severe_Whereas_93 for a detailed solution

The next problem drops next week, and it's going to step things up a notch.

To find out, we put three leading paid AI models – Gemini Pro, Claude Opus, and Claude Fable head-to-head against an Inter IIT Gold Medalist.
Each participant tackled the same problem under identical conditions. The challenge was simple: arrive at the correct solution as quickly as possible.
Who came out on top?
Watch the video to find out.

Hey everyone,

Question #5 (The Vault Auction) brought in some great entries, and two users completely cracked the logic. Shoutout u/Spring_Impact1169 and
u/bottleken for dropping top-tier solutions!

We’ve picked one overall winner u/Spring_Impact1169 who takes home the ₹500 voucher for submitting the most complete proof. We’re attaching a sample of their actual solution in the images so you can see how they built their framework. If you want to know what it takes to ace the Integral Cup exam, this is the benchmark: clear assumptions, solid bounding, and zero fluff.

Check out the slides to compare your steps against the winning proof.

Question #6 is coming next week, stay tuned! 👇

In short, Blue and Red bid sealed cash amounts each round to move a token starting at room S. The higher bidder pays their bid to the opponent and chooses the move, with ties going to Blue. Red wins if the token enters the Vault, and Blue wins if it enters an Exit. Both players see all balances and positions and play perfectly.

We need to find the minimum initial share of total cash in lowest terms that Red needs to guarantee a win, and submit p + q.

Take a look at the graphics for the complete graph structure and rules. Give it a shot and drop your reasoning or final values in the comments below.

Hey everyone,

Question #5 for the Mathlete Sprint is officially out, and this week we are tackling a problem in Game Theory called The Vault Auction.

In short, Blue and Red bid sealed cash amounts each round to move a token starting at room S. The higher bidder pays their bid to the opponent and chooses the move, with ties going to Blue. Red wins if the token enters the Vault, and Blue wins if it enters an Exit. Both players see all balances and positions and play perfectly.

Prize :- ₹500 Amazon gift card!

PS :- The prize will be given to 1 winner, the winner will be determined based on the quality and clarity of the solution provided, along with the timing of submission (earlier entries and hand written solutions will be given preference). You can also DM us a written answer if you feel like!

The solution will be out on friday!

Hey everyone,

Question #4 of the Mathlete Sprint is now live.

This week's challenge is based on Information Theory and asks you to compute the rate-distortion function for three independent Gaussian sources under a fixed distortion budget. The problem brings together concepts from probability, optimization, and source coding in a compact multiple-choice format.

Take a look at the problem statement in the image and let us know which option you think is correct. If you'd like, share your approach as well – we'd love to see different ways of tackling it.

Q :- If the total distortion budget is D=9,D = 9,D=9,

what is R(D)R(D)R(D), in bits?

(A) 1

(B) 0

(C) 1.5

(D) 2

Prize :- ₹500 Amazon gift card

PS :- The prize will be given to 1 winner, the winner will be determined based on the quality and clarity of the explanation provided, along with the timing of submission (earlier entries will be given preference). You can also DM us a written answer if you feel like!

The result will be out on friday at r/integralcup
