Not might, it does.

Basically the stuff is not reproducible without all 4 parts.

(And reproducibility is as such a topic in these algorithms, you literally start with random start points in your typical setup. In teaching setups, requiring a fixed random seed to make the number somewhat reproducible is the usual way, and still it's not always possible -> different software versions might produce different numerical results.)
