- _Microft 7y agoThe animation is a bit strange. I think it's meant to show which numbers will eventually end the cycle at 1. Having the numbers appear in the reverse order compared to what the rules are does not help, in my opinion. Take 16 and 5. While 16 is shown first and 5 after, the meaning is actually that you can get from 5 to 16 by applying the odd rule (3*x+1) and from 10 to 5 by applying the even rule (x/2).
- cyborgx7 7y agoOh, I see. It's about creating the set of numbers that do end up at 1 by starting at 1 and applying the operations in reverse order. That is neat. They should have explained that in the article.
- acqq 7y agoI understood the rule used. What I question is the: - usefulness of animation - the non obviousness of the numbers that are displayed, v.s. all other remaining in the observed range. At least, non animated version of end frame allows better comprehension of what is shown.
