Non-LL Affecting Orientation Algs

[watermelon]

ELL is orienting and permuting edges at once.

Most people who use ELL with LL would orient/permute corners in 1 alg, then use an ELL alg to finish off the cube.

I checked one (BR'D?RB'U?BR'D?RB') and that's correct. But I don't understand all the {B? as BLB'-BL'B} "comments"

Why don't you explain and check for yourself?

Neither did I (at first). But if you do BLB' BL'B, the 4 middle moves cancel out giving you B2. It should be more like B [L [B' B] L'] B. However, I'm guessing that site used an optimal solver to find its algs, so I don't know why there would be those huge cancellations...

Edit: The site says "This page is the presentation of a computer work that I did in summer 2000 and in the beginning of 2001." So why are there cancellations then?

Because it shows that those algs are actually combinations of 2 (or sometimes more) LL algs, and if you think about it this way learning is easier. If you check what the cancellations, they always solve F2L and then break it again.
