Re: Guess the Pattern

I'm happy to see a pattern puzzle where the answer can't possibly be a high-degree polynomial.

Re: Two more secrets

Actually, I was referring to the claim that
Spoiler:
all probabilities are negative. I though I was misunderstanding how you were using "probability" like I misunderstood how you were using "eliminate"
earlier.


But after reading your response, I'm assuming that was a typo.

Re: Two more secrets

So it turns out I don't have a proof of optimality; I was making an assumption about the form of the solution that it turns out I can't easily prove. I'm not (yet) convinced your argument works, though - I'm stuck here: From these equations, and the fact that all probabilities are negative, we can d...

Re: Two more secrets

The Guesser begins with every subset of size m of the set of numbers as a possibility. If there are two such subsets {a 1 , a 2 , ..., a m } and {b 1 , b 2 , ..., b m } of which their elements are mutually exclusive, the guesser may eliminate one set or the other from the list of possibilities, wit...

Re: Two more secrets

Cool puzzle! How about the following generalization: Instead of thinking of 2 numbers, you think of 3? Or m for some arbitrary m < N? And the adversary still chooses any of them to answer with when given a subset, but the guesser wins if the final guess is any of the secret numbers. I think I've wor...

This got me thinking - 18 is a really boring, uncool number. Like, unusually so, so much that nothing could be more boring or uncool. I'd definitely choose 18 as an ususual example of a number of unparalleled uncoolness.

In other words, 18 is a prime odd perfect square.
