GPT-5.6 reportedly solves Feige’s 1/e conjecture in probability

A user says a friend used GPT-5.6 to solve a long-standing probability conjecture: Feige’s 1/e conjecture.
- The conjecture concerns independent nonnegative random variables \(X1, \dots, Xn\) with \(E[Xi] \le 1\) and \(Sn = X1 + \cdots + Xn\).
- It states that \(P(Sn \le E[Sn] + 1) \ge 1/e\).
- The post presents the result as a notable surprise, with the author saying it is exciting to see a problem discussed over lunch and dinner get solved.
