3X 1@home

The 3x+1 conjecture is an unsolved conjecture in mathematics. It is also known as the Collatz conjecture (after Lothar Collatz, who first proposed it in 1937), as the Ulam conjecture (after Stanislaw Ulam), as the Syracuse problem, as the hailstone sequence or hailstone numbers, or as wondrous numbers per Gödel, Escher, Bach. It asks whether a certain kind of number sequence always ends in the same way, regardless of the starting number.

Paul Erdõs said of the 3x+1 conjecture, "Mathematics is not yet ready for such problems." This project seeks to find large solutions to this conjecture.
