Random Blindfold Cubing Discussion

[DrKorbin]

In 4bld I hate the cases for wings where I have two l-slice wings (like DFr-FDl-UFl). Can someone tell me a comm that would solve a case where the wings are Diagnol so either BUl-FDl or UFl-DBl. For adjacent I use x': [D2, U' l' U l]

DFr-FDl-UFl: r' [r' U2 r, D2] r
DFr-BUl-FDl: U2 l [l U2 l', D2] l' U2
DFr-UFl-DBl: x' U' R' U [U R U', l2] U' R U x or U' R x y' [R2, U' l U] y x' R' U

Anyone know/use this for UBR UBL DF BU? As an M2 solver with UBL corner buffer, I would get this parity case 1 in every 48 solves (i.e. whenever UB is flipped in place and I have parity).
U Lw U' R' U Lw' U2 Rw U' Rw' U2 R U'

I found it by hand today. Actually I was bored at work and figured it without a cube

Interesting. I always did F' M F' to set up, then T perm, then undo setup. (Easy to remember.) This is obviously better if I could learn to do it.

Actually pretty easy to remember too. Just a J Perm with wide moves

 

[DrKorbin]

I would suggest something like
y x U' R' U Lw' F' U' F R U R' U' R2
(derived from Aron PM's 22ll page).

I saw this post

Hmm... especially with these being so L-turn-heavy and even the nice cases having more L turns than R turns... maybe the L2 method would be better...

and couldn't find any algs generated for it (mainly the last few cases on this page where there are already algs, but they aren't great when mirrored). Here they are if anyone is interested. Most of the "alternative algorithms" are actually just the same algorithm written in a different way, but the first two are 2-gen algs that do the same thing as the 3-gen ones.

Have a comp this weekend. Will be happy if someone can answer asap.
What do I do if my last corner target is BRU or RUB and i need to fix parity after that? Is there a way to fix parity and also finish my last target simultaneously? OP btw.
Thanks.

How do you usualy fix a parity? What alg do you need?

 

[Cubo largo]

Can't get sub 2 with OP/M2. Suggestions or just training?

What are you splits?

 

[Cubo largo]

Dunno. I think around 50/60 for memo. Around a minute for corner memo+corner execution

 

[TheNextFeliks]

Improve memo. I was 60-60. Now I avg 1:30 with 30-60 lol.

 

[antoineccantin]

Improve memo. I was 60-60. Now I avg 1:30 with 30-60 lol.

Improve execution. I was 1:20-40. Now I avg 1:05 with 35-30 lol.

 

[DrKorbin]

Improve both.

Both. Start by working on one, and then magically the other will become faster. Faster memo means more fluent memory of the targets (hopefully). Faster execution means you don't need to remember for as long, and therefore you can memo faster.

If you execute without pauses, turn faster.
If you execute with pauses, think ahead more.

PUSH YOUR MEMO.

I'd also add that consciously trying to improve memo first can help your execution a bunch (if you can already turn fast) since you'll remember stuff a bit less, so it will force you to execute faster before you forget your memo. Personally, when I switched to audio edges, my edge execution also got faster for the reason I just described.

I'm Ok with fixing parity
Buffer to BRU and then fixing parity
Buffer to RUB and then fixing parity
Both of these seem to be painful. Any way i can fix parity and also finish the swap at the same time?

There are several ways to solve a parity. Since I don't know yours, it will be hard to help. How do you fix a parity usually?

Thanks. I'll practice

R D' y perm with F and F' removed D R'
M2/ OP
Average - 1:10 - 1:20
Incase my last target is BRU, I need to do R' F (y perm) F' R and then again R D' (y perm) D R' to fix parity. Anyway to finish both together?
Also when I have the corner UBR to be twisted clockwise or anti clockwise, it seems to be time consuming to twist the corner and then fix parity. Can both be done at the same time?
