COLLATZ-PROBLEM-TESTER

Just a minimal tester for collatz conjecture

Building

$ git clone https://codeberg.org/XDream8/collatz-problem-tester
$ cd collatz-problem-tester
$ cargo build --profile optimized
$ ./target/optimized/collatz-problem-tester -h

Usage

$ collatz-problem-tester -h
$ collatz-problem-tester [flags] <number>

Flags

random(-r, --random + -u8, -u16, -u32, -u64)

Test a random number. By default u16 numbers are generated With -u8, -u16, -u32, -u64 flags you can set how big you want your random number to be

$ collatz-problem-tester --random
$ collatz-problem-tester --random -u8
$ collatz-problem-tester --random -u16
$ collatz-problem-tester --random -u32
$ collatz-problem-tester --random -u64

verbose(-v --verbose)

Log everything that's going on(might cause performance issues for big numbers). Disabled by default.

$ collatz-problem-tester --verbose 6

optimised odd algorithm(-o, --optimised-odd-algorithm)

Optimised odd algorithm(instead of '3k+1' use '2k+2'. This will speed up the process a lot since this will reduce the tries that needs to be made to find the end result. Just try and see it yourself.

$ collatz-problem-tester --optimised-odd-algorithm 91
