Waffle's Roux Tutorial

...a U-perm^^

Scramble: M U' M2 U' M U2 M U2 M'. Solve EO: M'.
--> Nice! And in your EO of scramble 5, you set up with M' U2 M' and then you orient all with M, right?

 

[jms_gears1]

Has step 4c skipped radomly in your solution of the 4th scramble?

No, I used U-permutation.

What have you done in the solution of the 5th scramble at the beginning?
I don't understand your EO.

Sometimes I think it's better to leave F/B centers on U/D. The EO definition stays the same.

Here's an example where it helps a lot. Scramble: M U' M2 U' M U2 M U2 M'. Solve EO: M'.

ok so how do you do EO and L/R pieces at the same time like that? it doesnt make much sense to me.

i guess what i mean is how do you do it with F/B on U/D

I don't do them at the same time...? First EO, then permute UR and UL (preserving EO), then permute M. I don't understand what you're asking, please clarify.

 

[jms_gears1]

ohhh ermm never mind i saw what you did now....

the fifth scramble confused me a bit...

but my question is more along the lines of this:
How can you do EO with F/B centers on U/D?

 

[Johannes91]

How can you do EO with F/B centers on U/D?

The definition for UL and UR doesn't change: their orientation is correct iff the L/R sticker is on F/B/R/L face.

The definition for M-edges stays almost identical, too. You just look at their orientation relative to the M-centers instead of the faces of the cube. Put another way, if F/B are on U/D, every good M-edge becomes bad and vice versa.

That's it. Finding good solutions is (for me, anyway) a lot harder than if you always had U/D on U/D, but also more interesting and in some cases it saves many moves.

I guess I get the hang of step 4 (--> It's party time! )
When I have 3 bad edges on top I can choose between UM, UM' , U'M and U'M'. This is all you need for a good step 4!!!!!
I have done an average of 100...a lot of work...and my average is 14.48 moves Stm! I'm so happy!

Yup. 'Tis what I do too.

I've forgotten to mention that if you have bad edges at LU, FU, RU, FD and the UL and UR edges on UF and DF you can do an M to fix the EO and it solves the L and R edges!

Roux is all about learning from patterns that you find. Good job.

So true.

 

[darthyody]

I just got my first sub-30 avg of 12 with Roux and a PB of 20.54 seconds. I haven't really been using Roux a whole lot since I learned it in the last few months until the last few days. I figured if I want to do 2x2 fast I need CLL, and all that alg learning for 2x2 alone seems wasteful so it kicked me back into using Roux even though I have yet to learn a single CLL alg (still using 2LLL).

can someone please explain step 4's optimization at the bottom of this link?

The purple are misorented. The Alg on the side shows where UL/UR are. when you do the alg, UR/UL should be together (like you do in 4b) and can be placed into the position easily (completing 4b).

i dont see how though..

like with 5a.

i do an M, now they are next to each other but what do i do from there?

The "*" tells you that three misoriented edges have appeared on top. It says it right on top of these charts.

i saw that but i dont get what to do..

ok so this scramble
LR'FU2L2R2B'LR'UB2

DF+DB are misoreinted
UR is at DF and
UL is at UF

so from what rouxs site said is you do an M and three bad edges have appeared on top.

so i do M and UL+UR are next to each other but oriented differently.

what would the 'alg' for EO and UL+UR in this situation

 

[waffle=ijm]

First you would do an M like on Roux's site, this makes the top and bottom colors the B and F respectively. EO accordingly. Finish.

So it should be like this

M U2
M' U M
U' M' U2 M' U' M

it makes it so less moves are done.

ohh ok i get it now hmm

anyone want to try and generate scrambles for each of the cases so i can see if i understand it? itd be much appreciated. ive been trying to with cube explorer but im not sure what im doing most of the time...

cube explorer cannot do M slices.
