4x4 OLL Parity Algorithm [video]

[Derrick Eide17]

Any good you guys think?
Thats using innerslices though so im pretty sure you could still do the parity algorithm and faster using that with just double layer turns where there is inner slices.

Person in the video Is Hiroyuki Take btw.

Unfortunately it doesn't seem to work using double turns. At least not the way I'm doing it.

I'm still a big fan of Lucas's parity alg:
r U2 x r U2 r U2 r' U2 l U2 r' U2 r U2 r' U2 r'
(To do it on an odd cube, include the middle layer in the second r' turn.)

What about double parity, what do you guys generally use for that?

I use r U2' r' U2 r U2' r U2' l' U2 r U2' r' U2 x' U2' r2. Well, that's my alg, even if I never use it for speedsolves.
It's also related to the "regular" parity alg
r U2' r U2 r' U2' r U2' l' U2 r U2' r' U2 x' r' U2' r'.

Derrick: Hiroyuki probably optimized that parity for less regrips to his liking.

EDIT: His alg: r2 B2 (r'R) U2 (rR') U2 (Lx) U2 (rR') U2 r' U2 (Lx' lx) U2 B2 r2. He claims he averages 4.57 on it, by the way.

I found this myself, (not sure if anyone found it before)
The parity OLL Parity alg I use is : Rw2 B2 U2 Lw U2 Rw' U2 Rw U2 F2 Rw F2 Lw' B2 Rw2

If you execute this algorithm with r instead of Rw, and l instead of Lw, it becomes a pure orientation parity fix.

not trying to be mean but that alg is OOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOLD news

That's the one I use. That's the one Dan Harris uses. You just changed the notation to denote double layer turns.

 

[nitrocan]

no the thing i found is the r instead of Rw (or is that what you were talking about? )

 

[Cerberus]

I use that one too and get times at about 5 seconds (4.75 and 4.61 my 2 tries to be sure ^^) I am thinking about changing to lucas, but I don't think I will earn that much speed 5.30 and 5.04 my 2 tries there..

 

[Dene]

Can someone make a video of Lucas' algorithm done sub4 perhaps?

From Mr Cohen, is somewhere in the video section too

 

[Dene]

Oh thanks for that, that is good!

 

[DanHarris]

I use this one:

l2 B2 l U2 l U2 x' U2 l U2 l' U2 l U2 l2 U2 x U2 - to flip edges and twist front corners.

If I want to flip the edges alone, I add L and L' to the front and end of the alg respectively.

Other one:

Rr' U2 Rr U2 Rr' F2 Rr2 U2 Rr U2 Rr' U2 x U2 Rr2 U2 x'

It's very fast!

 

[rachmaninovian]

what is the fastest pure alg?

 

[Robert-Y]

Sorry for the revival but I was just also wondering the same thing. So far I know Syuhei's alg is quite fast. Also Hiroyuki Take's alg is good:

Well, yes, that's the vid in the first post.

His alg: r2 B2 (r'R) U2 (rR') U2 (Lx) U2 (rR') U2 r' U2 (Lx' lx) U2 B2 r2

 

[Robert-Y]

Oh sorry, I should really read the first few posts before posting anything ...

 

[rachmaninovian]

I use r' U2 l F2 l' F2 r2 U2 r U2 r' U2 F2 r2 F2
which I do as
r' U2 l (x) U2 l' U2 r2 (x') U2 r U2 r' U2 (x) U2 r2 U2

I can sub 4.5 easily with it.
I probably have to change to something better...like less rotations? xD
my pb is sub 4 i think. 3.98 if i'm not wrong.
