Formula and methodology
Formula: If n is even use n/2; if n is odd use 3n+1; repeat until one or the step bound.
The explorer reports the bounded sequence behavior without claiming a proof of the conjecture for all positive integers.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Starting integer — minimum 1; maximum 1000000000
- Maximum steps — minimum 1; maximum 1000000
Worked example
| Input | Value |
|---|---|
| Starting integer | 13 |
| Maximum steps | 1000 |
Reaches 1 in 9 steps; maximum value = 40.
Assumptions and limits
- Starting value and maximum steps are positive whole numbers.
- Intermediate values are kept within safe integer limits.
- The tool is an experiment, not a proof, theorem solver, or unbounded termination guarantee.
