I think I'm missing something. Wiki CxLL question?

[brunson]

(Question mark in title for Lucas)

Am I misunderstanding something about CxLL? I thought the following:

http://www.speedsolving.com/wiki/index.php/CxLL_D#CF_.2F_2x2x2

Would be where I would find alternative algorithms for a 2x2x2 LL with orientation correct, but two diagonal corners needing to be switched, i.e. Last step of Ortega or Guimond. This algorithm is what I'm currently using: (R U' R' U') F2 (U' R U R') D R2, you can also do any Y, N or V perm on a 2x2 and get the same effect.

Why don't the algorithms on the wiki do what I think they should? I figure a) the algorithms are wrong, b) I'm an idiot and I'm doing them wrong, or c) I'm an idiot and I don't understand what they're supposed to do.

Well this is what they do to a 2x2:
R U' R D' L2 D' L U L' D L2
L' U L' D R2 D R' U' R D' R2

They appear not to preserve the orientation or permutation of the D-layer, which is a basic requirement of any true 'LL' algorithm. I suspect they've probably just been entered incorrectly and need a bit of fiddling.

Well, thank goodness it isn't me. I was pretty sure I was doing them right, I thought maybe I misunderstood what they were supposed to do. Thanks, Cride5!

Edit: I guess this could have gone under the One Answer Question thread.

They are written incorrectly. They should start with R U' R' and L' U L, respectively. I wouldn't recommend going to the wiki for 2x2/CxLL, the links are all messed up and the algs aren't that great.

@brunnon No probs

I usually post wiki related stuff in this thread, but being in the Announcements section, it probably isn't the best place to do it. What about a stickied Wiki Discussion thread in the Help, support & suggestions forum?

@David
Yeah, I was definitely disappointed with the content for 2x2. I added a couple of OLLs, I'll try to clean it up a bit as I'm working on 2x2 for Boulder comp.

Do you have a site you like?

@Cride5
I think Help, Support and Suggestions would be a good place for it. I don't know how much traffic a section for just the wiki would get. I personally wish we could get more participation adding to the wiki. It's got a good start, but has a long way to go. People just seem to forget about it most of the time.

 

[Cride5]

Agreed, hopefully more discussion on it will make it more visible to forum members. Anyway, here's that wiki discussion thread..

Depends on what you're looking for.

other stuff: Erik's site. too lazy to find a link right now.

I'm using guimond right now. Just trying to pick up a few more efficient algs here and there before my next comp. Thanks for the links to your site, I'll check them out.
