[Help Thread] ZZ and ZB Discussion

[TDM]

I think I am going to learn zz-b at some point. Should I learn full coll first? Or just go for it?

Yes, learn COLL first if you want to learn ZZ-b. You'll need some of those algorithms for ZZ-b, so you may as well learn them first as they'll help in solves when you don't know the ZZLL alg.

 

[ryn ball]

Plus recognition of ZZ-b cases are based on COLL, so I think you can go and analyze COLL patterns. Why not 2GLL? it has the less cases compare to ZZ-b we have zz-porky to set-up the corner permutation, zz-orbit, CP set-up for the last F2l pair blah's proposal. And some of the 2GLL algs are combos of sunes so I think this subset is memo friendly.

I was thinking of suggesting ZZ-porky (either v1 or v2), but he asked for ZZ-b. Although now I think about it, I would never use ZZ-b unless I was eventually going to learn ZZ-a.

Me too I don't like zz-b, and I don't have plans to push my capacity to zz-a. But as far as I know some zz-b algs are also zz-d for example the z-perms, H-perms of zz-b in no corner permutation are also in zz-d so if you finish 2GLL subset you can memo algs that zz-b doesn't share with zz-d to have a full zz-b.

@TDM: I'm curious about your signature in ZZ-f? actually I don't know that can you share some info about it?

 

[mDiPalma]

ZZ-b is good for FMC.

But now that the missing link is found and that a lot of different minds are working toward an intuitive and efficient solution from <R,U> to solved, I feel that ZZ-d will be more fruitful in the long run than any other variant/method. Your choice to not hop on the bandwagon as soon as possible only limits your ability to collaborate in these discoveries and breakthroughs.

I'm not sure I fully understand what you're saying. Is it to learn 2GLL first so you have less ZZLL to learn? But surely that involves learning more than just ZZLL?

@TDM: I'm curious about your signature in ZZ-f? actually I don't know that can you share some info about it?

Idk, I just invented a LL method yesterday and gave it a letter. All it is is me being lazy and finding a way of not having to learn so many algs. But it could be a really good method. I'll share info when I have good algs for all the cases (two left; I posted in the Request An Alg Thread). I'm only using it for OH, so I'm asking for L' and U algs, but it could be done with R and U for 2H.

 

[TheNextFeliks]

Really, 2gll algorithms aren't as nice as they sound. And cp recog stinks. Zz-porky v2 is good. I'm considering it. But still. Other than zbll, I think zz-b has the most potential.

 

[ryn ball]

@TDM: correct getting 2GLL first then zz-b algs that doesn't share with zz-d but this will be more than zz-b/zzll algs cuz U-perms doesn't exist in zz-b if i'm correct (8 U-perms in every COLL in zz-d but less in H case).
If you finished that LL method we like to see it thanks!

You seem to overlook the fact that 2GLL is also a 1LLL.

And let me personally vouch for the opinion that 2GLL algs are MUCH nicer than ZZ-b.

Although ZZ-d may be a few extra moves (like 3), the fact that they are RU, and that you don't need to ever regrip, and that there are less algs to recall from, and that skips are much more likely to occur....more than makes up for the movecount.

ZZ-d recognition seems hard the first 2 or 3 solves (just like eoline used to, when we all began), but I'm sure anybody who invests a decent amount of time will be able to recognize the cp in just ~1 second.

ZZ-b only seems better because it is more familiar to you. But you should stand back and objectively compare the two.

Wait... so EOLines shouldn't be taking up a third of my solves?

Yep. For every COLL case, there's 8 U perms (one for CW and one for CCW for the solved edge being on F, R, L and B), 2 Z perms (swapping F with R or L), one H perm and one with solved edges.

If you finished that LL method we like to see it thanks!

It's already finished and I have the algs, I just don't have good algs for OH (which is what I'm using it for). If I was going to do it for OH and 2H, I'd need 4 sets of algorithms (R and U for right-handed 2H, R and U' for left-handed OH, L' and U' for left-handed 2H and L' and U for right-handed OH). For now, I'll just do the right OH version. I believe (but I'm not sure) that the reason why people use their left hands for OH when they are right-handed is because they can use the algs that are mostly R and U from 2H and they won't have to learn a lot of new algs. Because most people won't know the algs, they can learn OH with their better hand (for most people). The reason why I'm doing this for OH is because I'm only using it for OH. The main benefit of the method is 30 algs for a 1lLL. But if you know full 2GLL for ZZ-d, this method is pointless.

Yeah true. Now on the topic of zz-d. Porky v1 or v2?

 

[TDM]

Yeah true. Now on the topic of zz-d. Porky v1 or v2?

v1 is simpler and very easy to learn, but v2 is better. Your choice.

 

[ryn ball]

zz-porky v1 (2 algs only) well it is up to you atm I can't memo cases in v2 since I'm inconsistent sub 20 in standard zz I devoted my time lessen my f2l times and lessen my old habbit of extra aufs in LL.

 

[TheNextFeliks]

I should get sub-20 with zz before I learn any extensions. Time for 25-50 zz session.

 

[BaMiao]

The nice thing about zz-d is you can at least try it out without learning 2GLL. Just learn all the 2-gen COLL cases, and you'll at least improve the last layer while you learn CP recognition. No sense in learning dozens of algs if there's a chance you might scrap the method. You can't really say that about zz-b.

This. Also, you don't need to be sub-20 to start with different LL methods. I started with ZZ-porky v1 when I was averaging 40s with 2H ZZ.
Question: how many people know full 2GLL? I'm hoping this number is small because then my method will be more useful.

Very few. I think Mdipalma does. Idk who else. What is your method?

 

[TDM]

Very few. I think Mdipalma does. Idk who else. What is your method?

I call it ZZ-f (letters a-e have been taken). I made it for OH, but it could be used in 2H as well. I'm going to say now that this isn't entirely my idea; I have used different methods and put them together into one method.
ZZ-f
ZZ-f is basically a way to reduce the number of algorithms needed for 1lLL when using ZZ-d or ZZ-e. There are 84 2GLL cases, but only 30 of these are needed with ZZ-f. These cases can be learned as a start to learning full 2GLL, which is a better method.
The method:

1. EOLine.
2. Complete half of the F2L.
3. Permute corners with ZZ-porky v1. You can use v2 if you already know it, but this method is designed to use as few algorithms as possible.
4. Finish the F2L except for slot, which can be in FL or FR, depending on whether you are using 2H or OH, and which hand you are using.
5. As you complete the F2L, phase the LL edges. Combining ZZ-b and ZZ-d/-e is the important step in this method. I phase intuitively, but you can also use the algorithms in the first link.
6. 2GLL using just 30 algorithms, listed below.

I've linked to most of the difficult bits (except EOLine for non-ZZ solvers). Here are the algorithms for the last step (ZZfLL? ZfLL? I'm bad at thinking of names).
Algorithms:
S=Edges are solved.
H=H perm for edges.
Zl=Z perm; swap F edge with L edge.
Zr=Z perm; swap F edge with R edge.
The image shows what position to have the U face in during recognition.
When referring to stickers, the three letters is corner position and two letters is the position of an edge. The first letter is the face the sticker is on.
You should only need two look at 2 stickers max (FU and FUL), but other info is provided. In some cases (where there's an oriented 2x2 block on U), it's easier to look at more than just 2.
Italicised algorithms are ones where I don't like the algorithm and am looking for another one.

Advantages and disadvantages:

Advantages:
-As with most ZZ variants with CP (-d, -e and -orbit), the solve is mostly 2-gen, including the LL.
-Just over 1/3 of normal 2GLL is needed (30 algs for 1lLL).
-Easier LL recognition.
-Very high chance of a LL skip. 1/27 for corners oriented and 1/4 for edges permuted gives a 1/108 ZZfLL skip chance. That's twice as likely as an OLL skip in CFOP!

Disadvantages:
-High movecount compared to ZZ-d (although not that much higher, probably 3-5 moves).
-Having to recognise both CP and Phasing can slow down solves, although not by as much when doing OH.
-There's no easy way to 2-look the last layer and keep edges phased in most cases, so before you know all the algorithms the phasing step is a waste of time.
-If you already know 2GLL, there is no point in learning this method (although I don't know of anyone who knows it).

I hope I explained it clearly enough. Ask if you want pictures for each individual case as that won't be too difficult to do, or if anything in my explanation is unclear. Also, please give suggestions for good algs to replace the ones I don't like.

I mirrored the algs. Seems like a cool method.

"TheNextFeliks", l'd advice you to go straight into ZZ-b, l also think that it has a lot of potential and all the algorithms can be Sub 2s (at least the ones l use).
