# What is the formula for Collatz conjecture?

The Collatz Conjecture can be stated as: using the reduced Collatz function C(n) = (3n+1)/2^x where 2^x is the largest power of 2 that divides 3n+1, any odd integer n will eventually reach 1 in j iterations such that C^j(n) = 1.

## What is the longest Collatz sequence?

Numbers with a total stopping time longer than that of any smaller starting value form a sequence beginning with: 1, 2, 3, 6, 7, 9, 18, 25, 27, 54, 73, 97, 129, 171, 231, 313, 327, 649, 703, 871, 1161, 2223, 2463, 2919, 3711, 6171, (sequence A006877 in the OEIS).

## Is there a prize for solving the Collatz conjecture?

The Collatz conjecture is an unsolved problem in mathematics which introduced by Lothar Collatz in 1937. Although the prize for the proof of this problem is 1 million dollar, nobody has succeeded in proving this conjecture.

## Is Collatz conjecture a millennium problem?

So it is not included in Millennium Prize Problems. Quite opposite. Many prices were restricted from awarding of solution of Collatz conjecture, because mathematicians already spent too much time trying to solve it.

## Can 3X 1 be solved?

It is one of the most infamous unsolved puzzles in the word. Prizes have been offered for its solution for more than forty years, but no one has completely and successfully solved it [5]. The 3X + 1 problem has been numerically checked for a large range of values on n.

## Why is the Collatz conjecture important?

Originally Answered: Why is the Collatz Conjecture important? It is important in that it is a mathematical conjecture which has not been solved yet. Many seemingly abstract theorums in pure maths have turned out to be very useful. As an example, I will cite prime numbers.

## Why is it called the hailstone sequence?

Such sequences are called hailstone sequences because the values typically rise and fall, somewhat analogously to a hailstone inside a cloud.

## Is there any proof of Collatz conjecture?

No, the Collatz conjecture has not been proven, hence the term “conjecture.” In fact, Collatz is nowhere near proved. It is among the least tractable problems in all of mathematics. This combined with the problem’s simple statement makes it quite peculiar.

## Is there any unsolved math problems?

The remaining six unsolved problems are the Birch and Swinnerton-Dyer conjecture, Hodge conjecture, Navier–Stokes existence and smoothness, P versus NP problem, Riemann hypothesis, and Yang–Mills existence and mass gap.

## Is there a prize for the Goldbach conjecture?

The famous publishing house Faber and Faber are offering a prize of one million dollars to anyone who can prove Goldbach’s Conjecture in the next two years, as long as the proof is published by a respectable mathematical journal within another two years and is approved correct by Faber’s panel of experts.

## What is the hardest millennium problem?

Today’s mathematicians would probably agree that the Riemann Hypothesis is the most significant open problem in all of math. It’s one of the seven Millennium Prize Problems, with \$1 million reward for its solution.

## How many Millennium Prize Problems do you think remain unsolved?

While one of the problems, the Poincare Conjecture, was famously solved in 2006 (with the mathematician who solved it, Grigori Perelman, equally famously turning down both the million dollar prize and the coveted Fields Medal), the other six problems remain unsolved.

## Why is 3×1 impossible?

Multiply by 3 and add 1. From the resulting even number, divide away the highest power of 2 to get a new odd number T(x). If you keep repeating this operation do you eventually hit 1, no matter what odd number you began with? Simple to state, this problem remains unsolved.

## What is the easiest math problem?

The Collatz Conjecture is the simplest math problem no one can solve — it is easy enough for almost anyone to understand but notoriously difficult to solve.

## Who invented 3x 1?

Whatever its exact origins, the 3x + 1 problem was certainly known to the mathematical community by the early 1950’s; it was discovered in 1952 by B. Thwaites [69].

## Has Goldbach’s conjecture been proven?

There is no known proof of Goldbach’s conjecture. There’s a conjecture known as Goldbach’s weak conjecture, which states that every odd number greater than 5 is the sum of three primes.
