A Collatz Variant with Increasing Odd Multipliers — Experimental Results
I’ve been exploring a custom Collatz-type dynamical system for the past couple months and wanted feedback from people interested in number theory / dynamical systems.
Instead of using a fixed odd rule like (3n+1), my variant uses increasing odd multipliers:
(1,3,5,7,\dots)
Definition:
- If (x) is even: [ x \to x/2 ]
- If (x) is odd: [ x \to mx+1 ] and then the multiplier updates: [ m \to m+2 ]
starting from (m=1).
So the odd multipliers used successively are:
[
1,3,5,7,\dots
]
I ran computational tests for starting values up to 10,000 with a 200,000-step cutoff.
Observations:
- A small minority quickly reach small numbers like ({1,2,3,4,5})
- Most trajectories instead grow extremely large and never returned within the computational limit
- I also proved there are no cycles in the full ((x,m)) state space because the multiplier strictly increases after odd steps
I wrote a short experimental paper about the system and I’d appreciate feedback, criticism, or suggestions for further directions.
I’m not claiming a breakthrough — just sharing an interesting dynamical-system experiment inspired by Collatz.
