The Collatz Conjecture is one of the Unsolved problems in mathematics, specially in Number Theory. The Collatz Conjecture is also termed as 3n+1 conjecture, Ulam Conjecture, Kakutani’s Problem, Thwaites Conjecture, Hasse’s Algorithm, Syracuse Problem.
If you keep repeating this procedure, you shall reach the number 1 at last.
» Starting with 1 — we get 1 in first step.
» Starting with 2 (even) — we get 1 in second step and in one operation
» Starting with 3 (odd) — we get 1 in 8th step
Similarly, you can check this conjecture for every positive integer; you should get 1 at last according to this conjecture.
Let be a positive integer. Then it either be even or odd.
A. If n is even: Divide by and get . Is it 1? — conjecture applies on that positive integer. Again if it is even — redo the same work. If it is odd, then— see next step!
B. If n is odd: Multiply by & then add to find . Is it 1? — conjecture applies on that positive integer. Again if it is even — redo the same work you did in A. If it is odd, then— redo the work of B!
Problem in this Conjecture
This conjecture has been tried on various kind of numbers, and those numbers have satisfied the Collatz Conjecture. But the question is that –
Is this conjecture applicable to every positive integer?
Mathematicians have found no good use of Collatz Conjecture in Mathematics, so it is considered as a useless conjecture. But over all, it is unsolved — and we can’t leave any unknown or unsolved problems & principles in Math.
