The "Request an Alg" Thread

[Brest]

Does anyone have a better algorithm than y' (L U2 L') (U L U' L')? This case is annoying for me, and I feel like there is a way to do this without a rotation.

Suggestions? Or should I stick with y' (L U2 L') (U L U' L')?

R' U R U' R' U R' F R F' R

or
F R U R2' U' R F' R' U' R
U2 F R U R U' R' U R2 U' F'

or just rotate

Can someone provide me with a list of useful 4x4 and 6x6 parity OLL cancellation commutators?

If you're looking for using setup moves to solve OLL and OLL parity together, see:

http://hem.bredband.net/_zlv_/rubiks/4x4/444ollpar.html

(I also have a partial list of RrU 3-gen OLL parity algs but I gave up on completing it because most of the algs are horrible. This one is (relatively) nice though: R U 2R U R' U' r2 R U2' r2' U r U2' r' U2 r U' r2' U2' r'.)

is there an alternative to this L2E alg that does not require annoying back slices?
B2 Rw' U2 Rw' U2' Rw B2 Rw U2 Rw U2' Rw' U2 Rw U2' Rw2

(Rw' U2 Rw2 U2 Rw U2) Rw' (U2 Rw U2 Rw2 U2 Rw') ?
Would help if you tell what method you use.

I think he meant the question for 5×5×5 L2E.

There's (R Bw R' D2)5, which is a regripless alg, but it's kind of long and the D2 moves suck. You could also just do a flip to convert it to a nicer L2E case: F U' R U r U2 r U2 x U2 r U2 3r' U2 l U2 r2.

I couldn't resist but to post this even longer algorithm of the same nature!

(L U Rw U' L' U2 )5

(The Rw move can be inverted to have the same effect, but I think this is the "regripless" version.)

@cuber314159, you can also check here in the wiki.

I don't understand why everyone uses conjugated Y perm for this COLL case... what do you guys use and why?

All the algs in this set suck. At least if you use a conjugated Y perm, it's (i) not too much slower and (ii) you already have muscle memory for the alg.

This one is decent as a ZBLL alg: (y2) R' U R U' x' U L' U L U2 R U' R' U (x). As a COLL alg though, it has an x rotation at the end which makes transitioning into EPLL annoying.

(What I use, personally? I know ZBLL for half of this set and I've been putting off learning the other half since forever. soon(tm))

Honestly the set up alg that you used isn't too bad. Brest's alg is nice, I should probably switch but I don't mind conjugated y-perm.
Wide T-perm also works (Rw U R U' Rw' F R2 U' R' U' R U2 R' U' F').

I do know all the ZBLLs for this set and can confirm that, as xyyxz said, the algs for this set aren't very nice.

Brests alg IS conjugated y-perm

Oh, woops.

I did mean the 'traditional' conjugated y-perm, but I also didn't realize that brest's alg was one too.

My mistake; thank you for informing me.

 

[PapaSmurf]

That is definitely one of the worst sets. Conjugated Y perm isn't too bad imo. Here are all my ZBLL algs, in the order that alg.db lists them:
R' F R U' R' U' R U R' F' R U R' U' R' F R F' R
L' R' U2 L U2 R U' L' U R' U R U' L
(U') F2 R U' R' U' R U R' F' R U R' U' R' F R F2
(U) R U' L U L' U R' U' l U2 R U2 R2 x
(U') r U R' U' r' F R U R' U' R F' R' U R
(U') R' U' R U L U' R2 D' R U R' D R2 L'
L U R' U L' U2 R U' R' L U L' U2 R
(U') R2 F' R U R' U' R' F R2 U' R' U2 R2 U R' U R
(U) F U R U2 R' U R U R2 F' r U R U' r'
(U2) F R2 U R' D R2 D' R U' R2 F' R U' R'
(U') r U R' U' r' F R2 U' R' U' R U2 R' U' F'
(U2) R U R' F R2 U R' D R2 D' R U' R2 F'

Hope this helps! And to be honest, just learn the whole set. And diag pi. They're the two where the ZBLL is worth it but not the COLL.

2X2 question: Is there an easy alg for when you're making the first face in Ortega and three of them are on the bottom, but the last one is on the U layer?

 

[AbsoRuud]

I usually do an R2 or L2 or whatever, so that one sticker from the bottom matches the one on top, then do a U or U' and then do R2 or L2 again. Hope that helps.

How did I not ever figure that out??? Thanks!

This case from the back (credit to ruwix.com)

I currently use U (R' U R) U2 (l U L' U' M') but I feel it isn't very effective

Also, I don't want any rotations
