OK. So I have a new method. At least... I think. It is for solving the centers for reduction in a heavily algorithmic manner, which is the most effective way to solve for me. I have one problem. I want a more efficient way of checking that your centers are correct. Preferably, no need to check at all. Just an algorithm that swaps centers and inserts F2L pairs. I also don't know if this is a method already. This is also not a method for speed solving, just for being more efficient at reduction method. If you'd like to help or know how it is done, please request it by replying or PMing me. Thank you!
