The Nineteenth Byte

In formal language theory, computer science and linguistics, the Chomsky hierarchy (also referred to as the Chomsky–Schützenberger hierarchy) is a containment hierarchy of classes of formal grammars. This hierarchy of grammars was described by Noam Chomsky in 1956. It is also named after Marcel-Paul Schützenberger, who played a crucial role in the development of the theory of formal languages. == Formal grammars == A formal grammar of this type consists of a finite set of production rules (left-hand side → right-hand side), where each side consists of a finite sequence of the following symbols...

DLosc

Aha, yes. I was trying to think if I've ever had that experience (definitely have if you change "yesterday" to "several months ago"), but then if you're writing BitCycle, that makes a ton of sense.

des54321

complicated bitcycle code is easier to write if you separate it into sections, but then you have to make sure each section cleans up after itself

DLosc

Yep. And then when you golf it, you smush the sections together and get rid of as much of the cleanup code as you can. :P

i think im gonna try to write a proper explanation for how this works before i post it, but i think my brain needs to not think about bitcycle for a bit before i do that

I'm pretty sure this is the first time anyone has used the H collector X^D

it is quite possible that this doesnt need quite as many tiers of collectors as it has, but i use every collector from A to H at least twice

@emanresuA thats why you always gotta send your bits to another collector first, and then send that one into the first collector
