Roux 4b to 4c Transition

So I was learning Roux and I actually liked 3-cycles cause my recognition and look ahead were horrible and they had a low movecount.
That was, until I started getting used to them and actually looking ahead. I couldn't look ahead to these cases, so I looked for a good way to do it and here I found it.
I have been using it and I average about 23 seconds with Roux now, thanks to this recognition method making my LSE feel WAY smoother because I'm actually able to look ahead to 3-cycles easily. I'm not even taking an extra look or really tracking pieces to identify the cycle. My very first Roux PB solve was 3:24, and now it's 12.82 (NL) in less than a month.

Now I really like Roux. THANKS. :D

Okay let me try again to explain more consisely. M' U2 M' U2 M2 U' M2 to set up case.

Okay so I identify any two colours on top that match each other in this case i'll choose RU and BU as they as both the same colours. When i do a m2 to finish 4b the BU edge will go to FD and the RU sticker will stay where it is.

So 4b done, I now do a U' to put the RU edge opposite to the FD edge. Okay now here's where it stuffs up. It doesn't work because after you bring the sticker that doesn't match the centre towards it with a M you can't find the last two moves to solve it instead it goes into another 4c alg. the U2 M2 U2 one. Please help or tell me what you don't understand from my explanation.

Btw thanks heaps for replying so quickly you're super helpful.

Hi, I also am trying roux and kinda have some sort of solution.
You see, the UL sticker is 'matched' with the ULB and UFL stickers into some sort of bar. When you see that, do the M2, then see if the top and bottom layer stickers are diagonal, but don't try to put the top/bottom layer stickers diagonally if they aren't. If they are not diagonal, leave them not diagonal (in this case it's an M2 and then U) do an M2 and then you can line the top/bottom layer stickers diagonally (using U2). Sorry I am not that good at explaining... Hope it helps. and the solution is just the mirror of your set up

If I add a Z-Perm to the Setup M' U2 M' U2 M2 U' M2 M2 U M2 F2 M2 F2 U' M2 - I still have some sort of bar to the left, but M2 U M2... if no good anymore.

Next I tried M' U2 M' U2 M2 U' M2 E2 M' E2 M - A real bar to the left again, but M2 U M2... is still no good.

I feel like you didn't mention the decision tree to use after: If 4b is finished , U-corners are aligned, non-diagonal edge case then ... ???

...
a) see a double-isolated edge at UF than U2 M ...

... to be continued
 
hello all,
ive been hard at work learning roux, and ive watched Donavons roux tut, 5dld, and others, I get lost when I have 2 edges not orientated the right way I tend to do the 2 edge flipper to fix them because I get lost on the right way to do it. does this seem ok or should I work on forcing my self to doing it the way its being taught on here.
my 2 edge flipper alg. 2 wrong orientated edges on top of the cube opposite of each other on the M slice I do this alg
m'um'um'um' u2 m'um'um'um' or if I have 4 edges on top that are wrong I do this one m'um'um'um'u u2 m'um'um'um'u' thoughts on these thanks guys
 
I'm playing around with those and I'm getting lost on which ones are being fixed can you please explaine these

When you do an M or an M', the orientation of the four edge pieces in the M slice change. So edges that are not oriented become oriented, and edges that are oriented become not oriented. Start with the initial orientation of the edges before the algorithm, and track the edges that aren't oriented as you do the algorithm, if you want to understand how it works.
In my opinion, understanding the algorithm isn't very important. :p Just memorize it and practice it a lot.
 
I have a nice strategy too; I identify BU sticker as I insert LR edges.

Could somebody explain that a bit more detailed? I've spent a lot of time to try to understand what you are doing, but i can't imagine, what the BU sticker helps you to do?
 
Hey guys I've been rouxing mainly working with the les for fixing them and after a few times or about an hour I can get them flipped now with little or no thought its easy now thanks
 
the BU sticker allows you to know what case LL is with only looking at U and F faces

And how do I know what case it is? Is there a collection with pictures+algrhitm? I know, that there are 4 FUU cases, but I don't know how I should recognize them... I'm sub 12,5 but I always just solve the centers and then the D edges, I hate this step...
 
the last step of roux isn't a collection of cases, if you've MU'd enough you would know all this stuff and be able to do it intuitively. actually you don't even need to know roux to figure it out.

See if the edge is connected to the center or not. You can determine the direction of the cycle.
 
I'm unable to make a video. All I can do is say that I know what I'm talking about. I used many different techniques, including user suggestions and others of my own, for 5 years and wasn't satisfied. I've been using this for close to a year and it feels perfect.

To everyone: Try it. Use this for a while. Maybe even just give it 30 solves to get used to it.

Hi Athefre. Indeed this is nice and simple, but what about the method we came up in like 2010? Which was to track the edges that land on the sides before the last U/U' of 4b step, and then according to them make either U or U'. Using that method we are able to start the U2M2U2 and E2 case with the U2 already done (I know that the E2 is not necessarily a bad thing, it is the U2M2U2 that I am more concerned about)
 
Really nice transition, it really removes recognition pauses and smooths out lookahead.. Thanks :)
 
i would rather look ahead and add an extra move than pause
in fact in normal recognition i sometimes have to do an M2 to be able recognize the cycle.
but it sometimes adds an extra move.

true, i agree. BU recognition method is a much harder recognition that Alexander Lau ccreated that works and without adding an extra move. give that a look if you want.

i see you have made tutorial on it.. Thank you for the suggestion and by the way its a great honour to get a reply from the great GuRoux.
