[Help Thread] Yau4 Discussion

[Piotr Grochowski]

So reduction method (4x4) is this:
1. construct first center
2. construct second center
3. construct third center
4. construct fourth center
5. construct last 2 centers
6. construct first edge
7. construct second edge
8. construct third edge
9. construct fourth edge
10. construct fifth edge
11. construct sixth edge
12. construct seventh edge
13. construct eighth edge
14. construct ninth edge
15. construct last 3 edges
16. solve like 3x3x3

What is Yau method, then?

There are not 24 edges on a 5x5. Still only 12. Otherwise, the differences between Yau4 and Yau5 are, as I understand it: 3-2-3 edge pairing doesn't work on 5x5, so you need to do freeslicing or AvG, or some other method, and some people solve the fourth cross edge before solving the last 4 centers. I never had much luck preserving the last cross edge while solving centers, so I did the same order as on 4x4.

 

[Piotr Grochowski]

There are 12 paired edges on a 5x5, but 24 need to be placed (3-1=2 for each edge). So you need to count to 24 to give the steps in Reduction5.

 

[Ronxu]

you need to count to 24 to give the steps in Reduction5.

No you don't. Stop making it unnecessarily complicated. Why aren't you breaking down 3x3 stage to pairing 1st F2L pair, inserting 1st F2L pair, etc?

 

[Piotr Grochowski]

No you don't. Stop making it unnecessarily complicated. Why aren't you breaking down 3x3 stage to pairing 1st F2L pair, inserting 1st F2L pair, etc?

Because 3x3 solutions may differ. Some solutions, like Petrus, don't do F2L pairs. Also this isn't unnecessarily complicated, because everyone really does it like that.

It's dumb to break it down that far because you get completed edge pairs all the time.
1. centers
2. edges
3. 3x3
Is that really so hard to understand?

It isn't dumb, because Reduction5 is exactly to do each of 21 edges one at a time plus the last three.

 

[xyzzy]

There is exactly as much information in "construct first edge; construct second edge; […]; construct twenty-first edge" as "construct 21 edges one at a time". There was no need to spell it all out. Also, not everyone does this—in fact, most speedsolvers don't do this, because it's very inefficient; freeslice is by far the predominant edge pairing strategy for 5×5×5 first eight edges (along with slice-flip-slice for the last four edges), with a significant minority using AvG.

Also also, this thread is for Yau on 4×4×4; please take the off-topic discussion about 5×5×5 to the appropriate thread(s).

I can't move my posts. I'm not an administrator. Also, one at a time is the standard Reduction and Reduction5 way to do it, using the algorithm l' U L' U' l, Uw' R U R' Uw or whatever was learned. It is simply not reduction with a different method.

No. As long as you solve centres and edges with the intention of reducing the cube to a 3x3, it is considered reduction, regardless of how you solve the centres or pair the edges. Yau and Hoya can be considered variations of reduction in this respect.

However, traditional reduction simply consists of centres, edges and 3x3 stage, and the predominant edge pairing method when doing this is freeslice. Yes, other methods (like one by one) exist for edge pairing, but it's still reduction.

 

[Piotr Grochowski]

Freelyslicing in Reduction and Reduction5 is like using VLS in CFOP. It's just not the standard Reduction and Reduction5.

 

[shadowslice e]

Freelyslicing in Reduction and Reduction5 is like using VLS in CFOP. It's just not the standard Reduction and Reduction5.

It is still a reduction method. Just like how CFOP is still LBL.

 

[Piotr Grochowski]

It is still a reduction method. Just like how CFOP is still LBL.

Just like CFOP is not standard LBL, a reduction variant is not standard Reduction.

Hey everyone, I am needing some help with learning the Yau method for 4x4. Any help or tips that you guys can give me, would be greatly appreciated.

Thanks!

I assume you have looked at tutorials, so my suggestion would be do not just watch one persons tutorials. Look at a few different ones, and maybe read some tutorials that will help you learn

I have watched Jperm's tutorial, but just the beginner's tutorial. none of the advanced, or 3-2-3 edge pairing, so thank you!

i watched jperms too, his is good, but like cubable said, watch multiple tuturials, and when you get that down definantly learn 3-2-3
