What the Algorithms actually do?

[Arkwell]

Guys, someone on the site once explained what the PLL's/OLL's actually do(ie: insert an edge, swap a corner) and I was wondering is there a place that explains what algs do or is it the product of lots practice till you start to see what they do?

Are you sure you don't mean "how algorithms work" ?

Pll isnt that confusing to work out... For other alga you could just track each piece individually

In OLL and PLL, in a lot of the algorithms, you take out F2L pairs and insert them in different ways to change the orientation and permutation of the pieces.

I was recently thinking about making videos about what the algorithms actually do, but I realized that it'd be pretty boring since it's basically just tracking multiple pieces slowly during an alg.

They are a set of moves that solve a certain situation/case/problem.

In OLL and PLL, in a lot of the algorithms, you take out F2L pairs and insert them in different ways to change the orientation and permutation of the pieces.

I think this applies more to OLLs than PLLs, although there's some PLLs (Y-perm, T-perm, I guess the G-perms are sort of like that too if you think about it) that take out the F2L pairs.

J
L
G
T
Y
Z (RU one)
R

Common algs for those cases are predominately take out pair(s), do stuff, reinsert pair(s) (differently.)

Well I guess more generally, you could say that you take out "peices" and put them back in different ways, to correctly orient/permute pieces. When you apply this to "F2L pairs" this will only be the case sometimes; but "pieces," even though it is more general, is more correct.

 

[asportking]

Different algs work in different ways. Of course, there's a few "methods" (like taking out F2L pairs, doing stuff, putting them back in) that some algs follow (a lot of OLLs and PLLs follow the F2L "method"), but really the only way to figure out what each algorithm does is to just go through it slowly, paying attention to what each turn does, and you'll eventually understand how the algorithm works.

All that's happening is the cube is rearranging everything and ends up fixing itself. There is not much you can learn about PLL unless you create some vast intuitive subset of it which wouldn't be very optimized.

Thi is how I prefer to think of it. However, if you want to see what the algorithms actually do. I believe LancetheBlueKnight's Website is still up and he has some images on their you could take a look at. Should be able to google it.
