Hi Rocknlol, I don't have a specific algorithm in mind, so much as I want to ask what the best algorithmic approach is to converting the puffer to a rake, which now that I say that out loud I think may be pretty specific to the rule.

It's nothing too technically impressive; I wrote a quick python script that iterates through all rules starting in B3 and runs gfind at a given speed/width for each one.
