Yet another OLS subset: OLS-FE

[samchoochiu]

(U R U' R')x3 and insert, don't have to do the first U
that works quite well for me (I can sub 1.5 it)

 

[advincubing]

(U R U' R')x3

That certainly works for this case -- where the edge is flipped, but corner is in the U layer facing up:

But to clarify, I was asking about case 38, where the edge and corner are placed in their correct slot, but the edge is flipped:

Thanks.

(R U' R') Dw (R' U2) (R U'2) (R' U R)

With this one I like to bring it up to the U layer with a R/F move and apply an edge flipping alg to flip unorientated U face edges (i.e. (M'U')*4(MU')*4 or (M'U'M'U'M' U2 MU'MU'M U2) and leave a nicer OLL (sometimes even force an OLL skip.) It may come in useful when all the corners are orientated, but it's not always fastest.

Maybe I wasn't clear enough.
Basically you do the trigger three times to form a pair, and then all you have to do is reinsert the pair because the pair is in the wrong spot.

(U R U' R')3 R U' R' U y' R' U R

That's a lot of moves

I do R U' R2' U2' R r U R' U' r' U2 R (U).

 

[uberCuber]

R2 U R' U' R' U2' r U R U' r' R'

 

[StachuK1992]

r (R U R' U') r' U2 (R U R U' R2) pretty nice pure

 

[advincubing]

r (R U R' U') r' U2 (R U R U' R2)

pretty nice pure

Indeed! Great algorithm.

Just out of curiosity:

Has anyone bothered to learn all of the algorithms yet or have I simply wasted my time?

I have to admit even I haven't learnt the algorithms yet haha

I only know the really cool alg for 3FE and solved CO, and I built the idea

I know Forte knows quite a few, but he knows everything so that's not particularly noteworthy

So, I asked this on the one-answer-thread (here), and got great answers already. But that's not a great place for follow-up. So, here's a thread dedicated to it.

I was looking for a better F2L edge flip algorithm than this: (R U' R') d (R' U2 R) U2' (R' U R). Based on the responses, it seems that this is the most efficient/common, and is the first listed on the wiki (#38):

(R' F R F') R' U2 R2 U R2' U R

Spoiler: OTHER OPTIONS ARE

Optimal Algorithms (9 HTM):
F2 U2 R' F2 R U2 F U' F
F' U F' U2 R' F2 R U2 F2
R U' R U2 F R2 F' U2 R2
R2 U2 F R2 F' U2 R' U R'

RrU Algorithms (10 HTM):

R U' r' R' U2 R2 U R2 U r
r' U' R2 U' R2 U2 r R U R'

RFU Algorithms (9 HTM):

F2 U2 R' F2 R U2 F U' F
F' U F' U2 R' F2 R U2 F2
R U' R U2 F R2 F' U2 R2
R2 U2 F R2 F' U2 R' U R'

I'm having a really tough time figuring out a rhythm/finger placement, etc. for (R' F R F') R' U2 R2 U R2' U R. I looked on Youtube for videos on this algorithm, but haven't found any. Anyone have good suggestions on technique/finger-tricks? Or a video?

Thanks.
