Collatz conjecture Prize 120 million JPY
A prize of 120 million JPY will be paid to those who have revealed the truth of the Collatz conjecture. The conjecture is also known as the \(3x + 1\) problem or the \(3n + 1\) problem.
Collatz conjecture
Repeatedly applying the function \(f(x)\) defined below to any positive integers will eventually result in \(1\).
\[ f(x) = \left \{ \begin{array} \\ x \mathbin{/} 2 & (x \equiv 0 \pmod 2) \\ 3 x + 1 & (x \equiv 1 \pmod 2) \end{array} \right. \]
