Random Cubing Discussion

[Cyrus C.]

What's this LL method called. You solve the EO and CP in one step, then the CO and EP in another step (this can be 2 gen)? Does anyone have algorithms for it or use it? If it hasn't been thought of, which I doubt, do you think it would be a good LL method?

I found r'drd'R'F'Uwf2Uw'FUwf2Uw'Rdr'd'r and Dan found U'[b'R2b,r][Fr2F',R']U.

I wonder if less than 18 is possible.

(RF'R'U2) (b'Rb Lw' b'R'b' Lw) (U2RFR') [16]

EDIT: A while ago Per found this:
(RF'R') (Lw'U2Lw u Lw'U2Lw u') (RFR') [14]

And now for something more beginner-stuff...

I am still using 2 look OLL and was wondering what you guys think of the following:
For all the cases with no edges solved, instead of using the typical beginners method alg F (R U R' U') F' f (R U R' U') f' use:
M U (R U R' U') M2 (U R U' r') instead.

The latter alg leaves CO intact so you for these cases you actually go to a "1 look" system; Still using 2 seperate algs but you know the 2nd alg upfront.
You could even AUF before the 1st alg so you can flow straight into the 2nd.
Offcourse for the specific dot case you would still use F (R U R' U') F' f (R U R' U') f' to OLL.

The algs from the CPEOLL wiki page will work (16 of them), but won't always be the best, because those algs care about CO.

Then, 2GLL algs. Check BOCA under ZZ under variation D. 84 of those, totaling 100 algs.

I think it could be decent.

Well, F (R U R' U') F' f (R U R' U') f' is really awful to perform, so I'd definitely suggest using something else. The one you suggest is one of my OLLs, and it's pretty nice. You might also want to try (F R' F' R2) r' U (R U' R') U' M'.


Don't wanna make a new post, so:
Obvious thing that people don't always realize: Your chance of a LL skip on 2x2 is always the same (1/(27*6)) before you see the scramble, but after you see the scramble this probability may substantially increase or decrease.

Often I have ideas or thoughts that I'd like to post or discuss, but there doesn't exist a topic for. This happens a few times a week and usually consists of method ideas that don't yet merit their own threads - I resorted to discussing RouxZZ in the accomplishments thread, for example.

Think of it like the one answer one question thread, but for adults.


To start us off, I wanna post a video of kirjavaparity ^_^

AHMAIGAWD!! I LOVE YOU!!

AHMAIGAWD!! I LOVE YOU!!

Cool story bro.

Wait...what?

anyway...Anyone else share my pain where you're learning a method, but still uncomfortably slow with it, and the temptation to switch back is growing way too much? At least with your first method there is no easy way out, the only way to solve faster is to practise.

Anyone have any tips?

5x5 method idea: Keyhole Style LBL
- 1x4x5 block, place it either on D with the free slot on F, or B with the free slot on U.
- Make the next three layers of the block, one layer at a time from B/D.
- You should now have two consecutive layers left. I suggest pairing centers, pairing edges AvG style (kinda like Yau with Uw moves), and then finishing with Petrus.

EDIT: 2:12.01, 2:08.49+, 2:18.37, (DNF), 2:01.29, 2:07.52, (1:56.42), 2:03.37, 2:18.08, 1:58.19, 2:03.20, 2:21.61 => 2:09.21

Yeah, I can't believe I found it by messing up a solve on the sim.

Improvement of above method:

- Build two opposite centers, place on L/R
- 1x4x5 block on L
- Make the next three layers of the block, one layer at a time from L, one center at a time and inserting the edge when appropriate
- Switch the solved 4x4x5 block to BD; pair edges (I suggest pairing a full one first, placing on DF, then using AvG with Uw moves) and finish with Petrus

EDIT: Got sub2 And a 1:40 single (would have been sub-1:40 if I hadn't had trouble stopping the timer).

Dan Knights Z perm: R B' R' B F R' F B' R' B R F2 U

Now reverse it: U F2 R B R' B' F R' F B R' B' R
WTF? It's a Z perm on D, plus the equivalent of an E move. I can't explain that.

Wooho! Just got my first speedcube! (had a non-lubed original rubiks) It's a FII, and I love it! Its still a little loose so playing around with the tension (read: struggling to get the caps off)..

/me is happy

A new method invented by myself.

Cross->1 pair of F2L->3 F2L edges->last layer EO and 1 corner at the same time->last layer EP together with 1 corner -> L5C

What do you think of it?
