I was wondering how the autocrafting system figures out what it needs to craft as i am trying to remake AE in cc: tweaked, and currently use a recursive crafting system, but that only supports 1 "core" per recipe, so I can't have 2 cores craft 8 planks and then have one of them make a chest; Is there some sort of paper or pseudocode of the algorithm?

Anything crafting related can be found here. Feel free to use it as inspiration.
Searching for something like constraint satisfaction problem and/or scheduling might also be a good place to begin.

Otherwise there isn't really any pseudo code for it. Probably even to complicated to really write it as such. Also I have no idea which limitation cc does bring with it and how it would affect it.
