DISCERNING NEW PATTERNS IN THE GENERALIZED COLLATZ FUNCTION UTILIZING BIG DATA ANALYSIS

The Collatz Conjecture has eluded mathematicians for decades. The small fact that for any initial number

*n*, when recursively inputted to f(*n)=n/*2 if*n*is even and f(n)=3*n*+1 if*n*is odd will converge to 1 is a point of debate in the field of math for almost 80 years. However, the Generalized Collatz Function is a relatively new function that is not studied by many. Using the logic f(*n)=n/d*if*n=*0(mod*d*) and f(n)=*mn*+1 if*n*is not equal to 0(mod*d*), where*d*is a list of consecutive positive primes until the*d*^{th}prime, the Generalized Collatz is a variable form of the Classic Collatz. We use Mathematica to run the generalized Collatz sequence 1 million times and use big data scanning tools to create visualizations with high-probability to contain a pattern. We discern three new patterns from this big data. One, that all numbers that are divisible by a prime number squared can be set to*n*, so that, with*m=n-*1 , creates a hailstone sequence ending in {4, 2, 1}. Two, that all generalized Collatz sequences with*m=n-*1 will converge to 1, for any divisor, in three iterations. Three, that all Mersenne numbers, when set to*m*, will, for any divisor and for any initial number, cycle. This project, with the help of 3D graphing technology, was able to find never before seen patterns in a thought-to-be unpredictable function, the Generalized Collatz Function.
