Anything you can do with a calculator is obviously trivial. Is there a clear point of departure when AI can no longer handle mathematical reasoning?
The IMO are a bit more involved... e.g. IMO 2023: > Problem 1. Determine all composite integers n > 1 that satisfy the following property: if d1, d2, . . . , dk are all the positive divisors of n with 1 = d1 Although ChatGPT 4 makes a pretty decent start on this already: > To determine all composite integers \( n > 1 \) that satisfy the given property, we need to closely examine the condition set forth: for a composi…
"The condition fails for i=1 since 1 does not divide p+q unless p+q is a multiple of n, which is not generally true" (1 divides everything)
In the second it gives up:
"However, this conclusion is based on heuristic reasoning and examples"
Third attempt it makes this mistake:
"If the immediate next divisor, di+1 , is not a multiple of p (for instance, it could be q or a product involving q), then p does not divide di+1. Hence, p will not divide the sum di+1+di+2 in such a case, violating the condition." (the fact that p does not divide d_i+1 does not imply that it does not divide d_i+1, d_i+2)
Then it gives up again: "However, this conclusion is based on heuristic reasoning and examples"
Then it makes this basic logic mistake: "However, since p and q are distinct primes, p does not divide q, and it's not guaranteed that p divides q+d_i+2 , especially if d_i+2 is not a multiple of p. Therefore, for such n, the condition fails." (the fact that "it's not guaranteed" doesn't imply that it's false)
Overall it proves that prime powers have the property, conjures that non-prime-powers don't, proves that p*q doesn't have it, but completely fails at coming up with a proof strategy that proves that non-prime-powers don't have the property.
