The Collatz Conjecture is a number theory problem that involves iterating a sequence of operations on a given number until it reaches one.
The problem is easy to understand but extremely difficult to prove or disprove, making it one of the hardest problems in mathematics.
Despite extensive research and computer simulations, mathematicians have been unable to find a counterexample to the conjecture.
The conjecture is named after German mathematician Lothar Collatz, who first proposed it in 1937.
The Collatz Conjecture is an active area of research and has connections to other branches of mathematics, such as graph theory and dynamical systems.
