The Roux "Example Solve" Game!

[h2f]

I haven't done one of these for a while so:
y'
R2 F2 U R' u2 U' R E'//FB (8/8)
R2 U2 R U' r' (U' R')//SB (5/13)
(R U) U R' U' R U R' U' R U' r'// CMLL (10/23)
M2 U' M' U' M' U2 M2 U M2 U2 M U2 M// LSE (13/36).

LSE sucks for FMC even in STM because you execute so fast but it's actually a lot of moves...

It doesnt work. Change rotation to y and E' to E in the end of FB:
y
R2 F2 U R' u2 U' R E //FB (8/8)
R2 U2 R U' r' (U' R') //SB (5/13)
(R U) U R' U' R U R' U' R U' r' // CMLL (10/23)
M2 U' M' U' M' U2 M2 U M2 U2 M U2 M // LSE (13/36).

Very nice blocks.

Very nice blocks.

Oops I really need to make sure that I get rotations and stuff right cause I really suck at that sort of stuff.

And thanks!

Try to make FB and SB shorter. 11 moves on FB is too long. My solution on the same blocks

Not only your first block is shorter but it also is very fingertricky.
I don´t use u's and r's move for the FB but I think I am going to start using them.
Also, how many moves do you recommend for FB? At the moment I am x2 y2 CN and trying to be x2 y CN so I can have more blocks to choose.

Thanks!

 

[h2f]

Thank you. I'm not even sub20 so I'm not an expert. If I remember it good for x2 y2 CN 9 is the limit for x2 y CN 7 but I'm not sure and 5,5 on average. I think you should try to limit it to 9 though. With x2 y CN it's easy to build blocks. Very ofthe there's a pair: slot or bottom and it's easy to expand. You will see. Try different ways of block building and you will find your way.

I try to get 10- for FB if there are no premade pairs or blocks (unless they are in very nice places). In general, if there is a pair or two I may try for 7.

Since there is no new scramble I propose this:

D' L2 R2 U F2 U' B2 R2 D F2 U' R F' R U F L2 B' U2 R' U'

/* Scramble */
D' L2 R2 U F2 U' B2 R2 D F2 U' R F' R U F L2 B' U2 R' U'

U2 F R U R' U' F'// CMLL
U2 M U M // EO
U' M' U2 M' U' M2 U' // UL/UR
M2 U2 M U2 M' // M perm

I have improved my Roux solves a lot since my last reconstruction (I was averaging 40-45s, I am sub-30 now) but yet I have a lot to improve, what do you think?

Here's what I found.

Efficiency on that solve was really quite good. SB could probably be improved, but overall you look to be doing quite well.

 

[Pandaroc]

So since i started cubing recently and still at the beginners stage (average between 1-2 minutes ) i thought i'll try this. Perhaps some other starters will try the examples too. I do them mainly for the Block practice. Well here is my solution (I do my cube with yellow/white L/R - was it called x2y colorneutral?)

Any tips to improve will be heard

My Roux is wierd, but here it is, my way through the scramble: D' L2 R2 U F2 U' B2 R2 D F2 U' R F' R U F L2 B' U2 R' U'
(for warning, I will accept tips, but if my solve ends up similar to others, just know it is the same scramble)
at first glance, I wanted no back moves, but I realized I can use them here well.
(no rotations to start.)
B D' L' // build a line on bottom
F U2 R' U' R U L U' L' // back left pair
R' U R U2 F' // front left pair
U' R' U' F' U2 F R2 U2 R'// front right pair
U R U2 R' U' R U' R' B U2 B'// back right pair
now to fix the F2L
U M' U' M2 U2 M' U M U' M'// finish F2L
to set up my partial OLL: y2
F R U R' U' F' U2 l' U' M U' L U l' U l// OLL
U' (x? I forgot which direction was which in terms of x, so do it like an l' R) R2 D2 R U R' D2 R U' R// pll
I know my solve is very move inefficient and that may because I do Roux- style F2L, but revised to be CFOP minus 2 edges at start. but total move is: 80 if you are counting like a fewest move competition I think. more if you do count full cube rotations.
(lol 80 moves is the top limit

Well, I wouldn't say that's really roux: more like a restricted less efficient form of FreeFOP

Anyway if you are going to leave the M-slice open, why don't you use it for pairing as this can be much more efficient than the almost standard F2L inserts you are currently doing? Also, why not orient edges while finishing F2L as then you could use an OCLL or COLL to finish it? This way is usually more efficient than having to do an OLL and has less algs.

Though i wouldn't recommend you do it the way you are currently doing it because Roux benefits from more efficient F2B via blockbuilding, here is my attempt (doing it your way and using the same start):
B D' L' (3/3)
D F U F' R' U' R D' R' U R (11/14)
M2 L U2 L' U L U' x U R' U' r U R' (14/28)
M' U M' U' M U M (7/35)
AUF to sune, J-perm (22/57)

But again I stress that if you want any real form of efficiency, use proper blockbuilding and proper roux or proper CFOP

 

[Zachary Palan]

yeah, I am moving to proper roux, just need to work on my middle usage for pairing for block-building. I just find the method I am using is helping me improve my lookahead, and that is always good but thanks! ill take the advice

Guys, sorry for the weeklong bump, but I'm curious if anyone has any critiques/improvement suggestions on this solve:

U' M' U2 M U'//ULUR & setup for BU prediction
M2 U M U2 M U2//ULUR insert and 4c

Because I am wondering which step I should focus on for 3x3. Thanks guys

U B2 L' F' L B' R' D R U2 F L R2 U2 L2 D2 U F D2 F' D2 R2 D2 F' B2

I would have a look at trying to influence the pieces of SB while doing FB when you get an easy inspection case ad make sure that you can solve any piece in any position (at the moment you seem to want to build blocks, set up pieces in the U layer). For example, I would have done U R U' R r U r U r U' R U M' U R

Also, don't put extra moves into your LSE (you have a U2 at the start and I can't work out why)

After researching for 6.84932*10^(-4) years and carefully studying a large number of other reconstructions, I finally present to you my 21st attempt:

Scramble: R2 U2 B2 L' D2 U' R2 F' B2 F2 D2 R U R' U2 R2 L2 D'

Solution:

R2 L2 F2 D R' U' B2 //First block

U R U2' R2' F R F' U2 R' F R F' //CMLL

Total: 39 moves (HTM)

Now, that is called an optimal Roux solution!

Wow! That's impressive. How long have you been using Roux? You have really efficient solutions and your LSE is amazing!

 

[AwesomeARC]

To be honest, I'm actually a beginner Roux solver. I decided to switch to Roux from CFOP quite recently, so I have very little experience with Roux. What guided me while I was developing the solution was not experience, but my interest in puzzle theory. Read on to see how.

My first attempt at that scramble was really, really inefficient. Now, the solution which I posted above is my 21st attempt. With each attempt, I enhanced my solution with bits and pieces from various other reconstructions. It took me around 6.84932*10^(-4) years (6 hours) to make it perfect.

I experimented with a lot of things while developing the solution (and I gave special attention to the second block). I developed several commutators and conjugates. I experimented with them and took note of what exactly they did to the cube and which parts of the cube they modified.

I combined/nested my commutators and conjugates for greater efficiency. I used them to do two or more things together (like creating a block while simultaneously creating a corner-edge pair).

Finally, when everything was over, I decided to work on move cancellation. That was my 21st attempt. It brought the total number of moves down to 39 from 42.

The CMLL I used is actually an OLL-CP (I don't know 1-look-CMLL) and the LSE was just lucky.

So, that's how I developed the solution. Honestly, it is one of my best successes ever.
