Which 4x4x4 OLL parity alg do you use?

r' U2 r U2 r' F2 r2 U2 r U2 r' U2 x U2 r2 U2

I use this. I used to use the first one you posted.

The OLL parity algorithms up there fix DP right?

No. This is an example of a double-parity algorithm (I pulled this from Blah's thread).

This is another form of double-parity which you probably haven't seen before. (It's one of my PLL parity 2-corner swap algorithms with all slice turns converted to wide).

Ah I see. How do you recognize whether you have double parity though? Instead of completing OLL parity and then realizing that you have PLL parity as well, is there a way to look and see that you have both?

I don't look ahead that much (I just do a double-parity algorithm if it is obvious that the cube contains it). I bet someone will be able to help you, though.

I'm not saying look ahead too far lol. Assume that I've completed reduction....started 3x3...gotten to OLL and realized that I have OLL parity. Is there something I can look for at this point that will tell me that I have double parity?

EDIT: Back to my original question as well. I still fail to see how Lucas's algorithm isnt a DP alg. When I perfrom the alg, two edges are switched across in addition to an edge being flipped. It performs the PLL parity alg as well as an OLL parity alg. Isn't the algorithm that you linked me to as a DP alg simply an OLL parity alg? That wouldn't solve double parity. That would still leave you with PLL parity as you're only flipping the edge.

@Puzzlemaster: 'Lucasparity' only solves OLL Parity. It switches 2 corners in addition to 2 edges.

DP algorithms generally only switch 2 corners and flip an edge.

Regarding parity recognition during OLL, the only practical way I know of is to recognise permutation while ignoring orientation, and seeing if it's a 'legal' PLL or not.

2nd one ftw

r' U2 r U2 r' F2 r2 U2 r U2 r' U2 x U2 r2 U2

Apparently this is the 'Hungarian alg'

I think my best with it is around 2.6-2.7, it's definitely a nice alg (Breandan said that he uses this, or your alg, depending on hand position).

Yeah I use this too, I found it on Stefan Pochmann's website.

I'm a bit surprised that algorithm isn't one of the main choices, I thought it's quite popular...

How do you guys do the U2 with that? Right double flip or left double flip or...?

I execute it like:

r' U2 r U2' r' F2 r2 U2' r U2' r' U2 x U2 r2 U2'

U2' = lefty double flicks...

I like waffles alg too

I use this alg too, I think it's pretty nice.

I use this one as well. I thought this was the one that everyone used lol

EDIT: (2.88), (3.90), 3.09, 2.89, 3.00,
I never do it that fast in solves though. My 4x4 sucks.

Lucas, I didn't see the poll (I never really scroll up when I click a link from the index, and it automatically puts the blue bar at the top, thus I don't see the poll. I'm pretty sure when I posted my response your alg wasn't a link, but I may be wrong (I just don't remember seeing a link). Even if the link was there when I posted, I doubt I would have clicked on it anyway due to the fact I didn't expect your alg tool to do anything different then standard notation would.

I use Lucas' alg CMOWLAPARITY!!!!111

 

[S1neWav_]

I used to use this easy to memorize pure flip but now i use Lucas' alg. (It's my alg too my name is also Lucas. Kappa)
