4x4x4 OP/DP algorithms (more finger-friendly)

OLL Parity (RUL):
Lw' U2 x Lw' U2 Lw' U2 Lw U2 Rw' U2 Lw U2 Lw' U2 Lw U2 Lw (25q, 17f)
Lw' U2 Lw' U2 Lw U2 Lw' U2 Rw U2 Lw' U2 Lw U2 x' Lw U2 Lw (25q, 17f)
Rw U2 x Rw U2 Rw U2 Rw' U2 Lw U2 Rw' U2 Rw U2 Rw' U2 Rw' (25q, 17f) (Yu Nakajima uses this, Lucas Garron found it)
Rw U2 Rw U2 Rw' U2 Rw U2 Lw' U2 Rw U2 Rw' U2 x' Rw' U2 Rw' (25q, 17f)

Double Parity (RUL):
Lw U2 Lw U2 Rw' U2 Lw U2 Lw' U2 x U2 Lw2 U2 Lw U2 Lw' (25q, 16f)
Lw2 U2 x' U2 Lw U2 Lw' U2 Rw U2 Lw' U2 Lw' U2 Lw U2 Lw' (25q, 16f)
Lw' U2 Lw U2 Lw2 U2 x U2 Lw' U2 Lw U2 Rw' U2 Lw U2 Lw (25q, 16f)
Lw' U2 Lw U2 Lw' U2 Lw' U2 Rw U2 Lw' U2 Lw U2 x' U2 Lw2 (25q, 16f) (mine, I switched )
Rw U2 Rw' U2 Rw U2 Rw U2 Lw' U2 Rw U2 Rw' U2 x' U2 Rw2 (25q, 16f)
Rw U2 Rw' U2 Rw2 U2 x U2 Rw U2 Rw' U2 Lw U2 Rw' U2 Rw' (25q, 16f)
Rw2 U2 x' U2 Rw' U2 Rw U2 Lw' U2 Rw U2 Rw U2 Rw' U2 Rw (25q, 16f)
Rw' U2 Rw' U2 Lw U2 Rw' U2 Rw U2 x U2 Rw2 U2 Rw' U2 Rw (25q, 16f)

Just for comparison, here's the "standard" OP alg:
Rw2 B2 U2 Lw U2 Rw' U2 Rw U2 F2 Rw F2 Lw' B2 Rw2 (25q, 15f)
See how much it sucks?

I can also post FRUL and FRU algs in case anyone's interested, but they're not as nice as the RUL ones imo. I think Yu Nakajima's alg is the best, here's why: no double turns (all Rw and Lw moves are quarter turns), and it alternates between Rw/Lw and U2 moves (i.e. quarter turn, U2, quarter turn, U2, etc.), which makes execution non-stop and super smooth. But I just like my alg better for some unknown reason

In case you didn't know, you can always use DP algs to fix OP. It doesn't really matter because it doesn't increase or decrease your chances of getting PP (still 0.5).

Edit: There, changed.

Thanks for those. I really like Yu's OP alg.

wow..I thought everyone uses the same algo..how naive of me..Yu's looks good I'm definitely trying it..

If the current one is not as finger-trick friendly I wonder why most people use it?

Btw blah, all the algs posted are basically for OP right since you can't predict a PLL parity anyway

Which one does erik use?

and also:

Man... that alg is NOT Yu's.

Lucas came up with that alg a while ago, and I've been using it for at least 10 months. Nakaji probably just found it from a few sources, one maybe being http://www.youtube.com/watch?v=84eud2DR2-s

Erik uses the standard one. I tried to get him to convert, but he didn't.

What times can you people get with your algs that you're using? I can get 4-4.5 secs (probably slow) with Frederick Badie's algs for OP and DP.

I never use the double parity alg, but I get sub4 pretty frequently with lucas's OLL parity.

I use the double parity alg, but I rarely need to. I only use it when I can easily spot that I have a double parity.

Um... what you do is you solve it and keep one edge flipped. If you find out at the end of OLL (with one edge flipped) that you have PLL parity, do a double parity alg. If you don't, then just use a normal OLL parity alg. Then you have to do a maximum of one algorithm.

i can get sub 4 sometimes with the Lucas OP...not so much during solves, but when im just practicing it. It is really good if u have good U2 double triggers...

yeah, its not nakajis algorithm but dont get so worked up dan....a lot of people just decided to use it after they saw how fast nakaji could perform it. (like me)

wowow I really like the last OP alg [Rw U2 Rw U2 Rw' U2 Rw U2 Lw' U2 Rw U2 Rw' U2 x' Rw' U2 Rw']. It took me less than a minute to learn it, I'm switching to it

Dude I didn't say he found it, all I said was "Yu Nakajima's", which could also (ambiguously) mean he uses it, which was in fact, what I meant. I doubt he even knows how to use Cubex or ACube.

I didn't know Lucas found that long ago. I just know I found it independently, and later accidentally discovered that Nakaji uses it too, and I don't know of anyone else who uses it, that's all.

I can get 4-4.5 on the "standard" OP alg, but I just don't like the feel of it, so I switched a couple of days ago.

And for those of you who still don't get it, I don't use any OP algs, I just use the DP alg when I get OP. Get it now?

Also, a suggestion for right-handers, you might want to try out those algs with lots of Lw turns, because then your left hand would just be doing quarter turns while your right hand does all the double triggers, the left-right alternating thingy is pretty much like an Air Jeff. I see lots of potential executing it this way

He's also better than you at 4x4

I can't find my OLL parity thread, but http://www.speedsolving.com/forum/showthread.php?p=80017#post80017.

Also, the first evidence of my parity: http://www.speedsolving.com/forum/showpost.php?p=52481&postcount=5
(I actually found it in CE first, but a huge search with ACbue never found anything better.)

More people need to understand that.

EDIT: I also don't know where I put my file with lots of parity algs, but if I find it I'll post it.
EDIT 2: Found a raw file with a few specific results: http://archive.garron.us/paste/text/dp_lrU2F2B2D2.txt

Now that I think about it, it seems so obvious. I've tried out a couple DP algs and have always been faster with them then OP. I never really got into waiting till PLL and checking Parity to decide if I should use a OP or DP alg, so I always just stuck to using OP when I got to OLL. Now I realize I should use DP because I'm faster with it. Thanks.

Saying that it's "Yu Nakajima's" implies possession, i.e. he found it. And Lucas definitely deserves mad props for finding such a fantastic alg.

Also I know most of the top American cubers on the East Coast use it, and I'm sure plenty of west coast cubers use it as well, since that's where Lucas is.

I'm pretty consistently 3.5-4.5 with Lucas's alg.

Only fast guy I know of who does that is Syuhei. Recognition is time consuming unless you've been doing that for ages like Syuhei.

I find it hard to do slice turns instead of wide turns, and I find it hard recognizing PLL with one edge incorrectly oriented, so I just orient 3 edges, do the standard alg, and continue with OLL. Anyone willing to find how to get and 2-look OLL case to be the headlights case with misoriented edge between the two misoriented corners (so alg completes OLL)?
