New and Shorter OLL Parity (Single Edge Flip) Algorithm! (23q)

[kaira504]

this is AMAZING....brilliant!!!

[speedcuber1995]

I can do it in 17 moves :p

@speedcuber1995

As I have stated in the title of the video, 23 is referring to block quarter turns, not block half turns. This algorithm is 16 block half turns.

Thanks for sharing, but:

1) You should write the algorithm like this to match standard notation

Rw U2 x Rw U2 Rw U2 Rw' U2 Lw U2 Rw' U2 Rw U2 Rw' U2 Rw'

2) I know this algorithm, and I have derived it in another one of my videos (Lucas Parity). It's 17 block half turns and 25 block quarter turns (25q). The algorithm in this video is briefer in both move sets. As another commenter stated, there are 15 block half turn algorithms as well, but none of them are less than 25q.

GAHHH MAKE THIS SLOWER I CANT GO THAT FAST!!!

lol I went WTF when the 4x4 suddenly got solved at the end.

Marvellous, thanks! The best is it doesn't affect ANY of the other blocks, where as the old way affected the top layer and set you back some. Transposed into what I know it's r2 B2 l' B2 r R' B2 r B2 D r R' D' B2 D r' R D r2. Now to go and learn it...

i know of a 15 move on the 4x4: R2 B2 U2 L U2 R' U2 R U2 F2 R F2 L B2 R2.

it works on all of the cubes i believe if you just use multiple layers. for example on a 7x7 you would use the first and second layer of just the second layer or first second and third layers:) oh yeah..........I AM THE SECOND COMMENT!!!!!! OH YEAH!!!!!!!:)

@TheAwsomecubeGuy

Well, it's r2 B2 U2 l U2 r' U2 r U2 F2 r F2 l' B2 r2. That alg is 15 btm (slice half turn moves), but that's not the move metric I am claiming my algorithm is significant in. In q turns (slice quarter turns), the 15 move alg you posted is 25q, whereas mine is 23q.

In addition, my algorithm is optimal in plain half turn moves, being 19, as opposed to 20 if you make just the first and last moves of the 15 btm alg wide. (Some people may consider r2 to be two half turns.)

nice
