[Help Thread] Roux Discussion and Help

[IRNjuggle28]

I don't believe you. It takes months to learn Roux.;P

Haha. This is my first day of actively trying Roux. I'd read about the Roux method before, so I had a previous idea of how it worked. And of course, my previous experience with CFOP helped me understand general speedcubing stuff.

Don't memorize them. Understand them. It is possible to solve L6E completely intuitive.

I can understand it. But that's more for solving at a slower speed. If I have to stop and think about intuitively doing it, it takes a bit of time. It's good advice; I will try to understand them better, but my main problem isn't understanding how the cycles work. The problem is differentiating the case that needs a clockwise 3 cycle and the one that needs a counterclockwise 3 cycle without pausing.

Cross pieces???

The cross? The first step of CFOP? Cross, F2L, OLL, PLL? Solving 2 blocks instead of the first two layers is the same, except I don't solve the BD and FD edge pieces, which are cross pieces in the CFOP method.

There is nothing in common?

Yes there is. The "dot" case is the equivalent of an H permutation: a diagonal swap of two sets of two pieces. The "half dot" is the equivalent of the E permutation: an adjacent swap of two sets of two pieces. The two FUUU cases are the equivalents of the A permutations: a counterclockwise and a clockwise cycle, respectively, of 3 pieces. And the odds of getting a L4E skip are the same as the odds of getting a CPLL skip.

Edit:
Someone may have already made such a thread, although I looked for one and couldn't find one. But I was wondering if anybody else thinks a "switching methods thread" would be a good idea? It could be both a help thread and an accomplishments thread, and switching methods is difficult and time consuming enough to merit its own thread. If others want something like this as well, I might start one.

It takes a day to learn but months/years to master.

It's not a great comparison but it's kinda similar to EPLL.

I don't know CFOP

what. surely you can ******** a 3LLL solve if you wanted to.

5bld mastered it in no time.

 

[IRNjuggle28]

I deleted a couple of my posts on this thread and moved them, along with a bunch of new stuff, to this thread, which is a support thread as well as an accomplishment thread, specifically for switching methods, that I just started. http://www.speedsolving.com/forum/s...g-Methods-Progress-Thread&p=947065#post947065

how do you predict the BU sticker

 

[IRNjuggle28]

how do you predict the BU sticker

For orientation of last 6 edges, you don't need to see the BU sticker. What step are you asking about?

 

[Renslay]

For orientation of last 6 edges, you don't need to see the BU sticker. What step are you asking about?

I think he refers to Step 4c) where you can solve the last 4 edge permutation looking only 2 sides of the cube IF you know (predicted) the BU sticker before.

 

[Bestsimple]

if you look at the centres and the BU edge you can recognise 4c.

 

[TheOneOnTheLeft]

how do you predict the BU sticker

When placing UL/UR, look at what other edges are in the U-layer before moving them from UF/UB to UL/UR (as this will usually be your last move of 4b). The sticker at RU or LU will become BU. With practice, you can predict earlier in step 4b by knowing what solution you're going to use.

 

[Bestsimple]

So i should start predicting BU after the orientation phase of lse?

 

[GuRoux]

So i should start predicting BU after the orientation phase of lse?

i think i'm in the same boat as you. i think what the best way to go about this is being able to predict whether you are going to do a U or U' for the end of 4b and use that time to look at what will be the BU sticker. then progress to looking at that piece while doing 4b.

 

[Bestsimple]

Yeah i think so, although the problem is predicting the BU sticker so late means you have to pause to look.

Wasn't sure if I should put this here on in this thread. Thought this thread was more fitting.

Would anyone mind explaining to me this page? http://grrroux.free.fr/method/Step_3.html I've learned the first 2 steps of Roux (not fast by any stretch of the imagination yet, but am trying to learn CMLL and this page is confusing to me. I'm not sure what the (A1) (c3) etc means. I assume they're annotations for the cell blocks, but what does it have to do with the algorithms? Some blocks have algorithms, others merely have annotations and the phrase "Sym". I'm rather confused, but this website seems like a good place to learn the method's basics.

I guess that the ones without algorithms are referencing other blocks in the table. The sym means that it's the mirror of the alg in that block and the ' means that it's the inverse. I wouldn't recommend this page though, because I don't think it's the best way for recognition. You should recognise based on colours in each orientation group rather than where the pieces are moving.

Do you already know 2look CMLL?

Thank you, that thread was helpful. What do the A2, etc stand for? I only know 2 look CMLL. I'm an avid Fridrich user, so learning 2 look took like half an hour haha. Should I just stick with 2-look and figure out EO phases? I have no idea how to do those or where to begin learning. Waffle's site is pretty helpful though.

Was that an unintentional CMLL skip, our you forced it?

A2, A3, ..., H6 are the names of the CMLL (CLL, COLL) cases. The letter stands for the orientation, for example, A is where all the corners oriented. Then numbers indicate which pieces are needed to swap. 1 is for nothing, 2,3,4,5 indicate different adjacent piece swaps, 6 is diagonal swap. Gilles Roux uses this kind of notation, see his CMLL table: http://grrroux.free.fr/method/Step_3.html
I don't know if he invented the notation, but it seems the general case notation in Roux CMLL.

For a two look CMLL, you need to know:
- Bx, Cx, Dx, Ex, Fx, Gx, Hx (where x can be any number) for the orientation, and
- A2 (adjacent swap) and A6 (diagonal swap) for permutation.

Note that A2 = A3 = A4 = A5 because of AUF, and also H2 = H4 and H3 = H5

There is a different type of case notation, see this table: http://www.speedsolving.com/wiki/index.php/CxLL

I personally recommend that you should start to learn full CMLL once you are about 30-40 seconds on average. Otherwise you can improve your times much easier by focusing on F2B (and CMLL) and lookahead.

For determining what you need to focus on, see the guides of http://rouxtorial.webs.com/miscellaneous.htm and http://wafflelikescubes.webs.com/sub15guidetoroux.htm

unintentional. do people actually force cmll skips?

 

[Renslay]

Never heard of that; but I can imagine that someone finishes his second block in a different way in order to skip the corners' orientation for example. Although I think it is much, much easier to force better EO after CMLL rather than better CMLL after SB.
