[Help Thread] FMC Discussion

[Cubenovice]

LOL, I am sorry about that. I guess my 40 - 50 move solutions is not going to help you FMC-gods anything.. LOL Thanks for the explanation.. I am going to do just that now..

no worries

BTW in your skeleton you can swap the edges AND solve two corners with the u2 alg I posted
But it needs one set up move so it takes you 12 moves...

Ah.. and all the way at the end you can use it to swap the two twisted corners in 10 moves thx to a cancellation on D

Yeah thanks, but I found that one out myself with a different alg. R2 U' R2 D B2 L2 U L2 D' B2

why uise a T-perm if you can use a cooler alg

 

[CubeRoots]

and second scramble:
D2 L' D2 R' D2 U2 R D2 F' U' F' D B2 D' F' L2 R' B' U2

ooooh just looked, lots of nice starts there will try tomorow

 

[Sebastien]

congrats on the 23 you got (and the 25) http://cubecomps.com/live.php?cid=201&cat=15&rnd=1

could you share the scramble?

Wow Sebastien, 23 moves is great!
Do you have the scramble for us?
Gus

Thanks! I'm very happy to have eventually beaten my official PB of 24 that I set 2.5 years ago when I was by far worse in FMC than nowadays. Also now I'm 2nd in Germany again!

Scrambles and my solutions from this weekend:

1st attempt: B L2 R2 D2 U2 F' U2 F' R F2 D R' U' L U' L2 F2 U2 L2

Lösung: 25 moves

Spoiler

Premove: B'
2x2x2: R' D2 R U2
More blocks: U' R U
switch and L4C: B R' F' D F R2 F' R' F R D' F D'

Skeleton: R' D2 R U R U D F' * D R' F' R F R2 F' D' F # R B'

No great start, but great cancelations (optimal):

* = F D' B' D F' D' B D (5 Move)
# = F' R B R' F R B' R' (5 Move)

Solution: R' D2 R U R U B' D F' D' B D2 R' F' R F R2 F' D' R B R' F R B2

25 moves.

2nd attempt: D2 L' D2 R' D2 U2 R D2 F' U' F' D B2 D' F' L2 R' B' U2

Lösung: 23 moves

Spoiler

2x2x3 on Inverse: B2 R' F' D B
F2L-1: F2 D' F
More Blocks: F D2 F'
switch and L3C: D F D' F' D R' D' R D'

Skeleton: D F D' F' D R' D' R D' F D2 F2 D F2 B' * D' F R B2

* = F2 D' B' D F2 D' B D gives 4 move Cancelation (optimal)

Solution: D F D' F' D R' D' R D' F D2 F2 D B' D' B' D F2 D' B F R B2

23 moves.

I had the solution afters 10-15 minutes. So many possibilities and great beginnings! I couldn't do better though within one hour. I'm curious if someone finds a better solution for this scramble!

3rd attempt: F2 R2 B2 F D2 L2 D2 F' R2 D' R' F' D F U' R2 B U' L2 U

Lösung: 30 moves

Spoiler

Premoves: U'
Pseudo-2x2x3: D L D' L2 B2 L'
More blocks: D2 R D' R2
switch und F2L-1: U B R' D' R'
L3C: D F D' F D2 F2 D' F2 D' F2

Skeleton: D L D' L2 B2 L' D2 * R D' R2 F2 D F2 D F2 D2 F' D F' D' R D R B' U'

* = D2 L' U L D2 L' U' L

Solution: D L D' L2 B2 L2 U L D2 L' U' L R D' R2 F2 D F2 D F2 D2 F' D F' D' R D R B' U'

30 moves.

Bad attempt, especially seen the decent start. I was probably too exhausted that Sunday morning to be fully concentrated. The fact that I just found a 28 move solution with block-commutator finish only while writing this solution down is confirm this. But...whatever!

Mean of 3: 25, 23, 30 = 26.0

After getting the 23 I had the following average of 12 out of official attempts:

26, 26, 27, 27, 27, 26, 26, 30, (DNF), 28, 25, (23) = 26.8

Sub 27! :confused: I really doubt that I will be able to do that again.

 

[irontwig]

My 28 was imo pretty boring, so I think I'll post my weird 3-edge skeleton for the third scramble:

D' R' U' L2 [2x2x2]

Switch to inverse:

U B2 R U2 R2 L' B2 L [Pseudo F2L-edge]
L' D L D' B' D' B D [Putting corners in the 6 move case]
D' B' D' R D R' B D B' R' [Leaving three edges]

This gives a 23 move skeleton: D' R' U' L2 R B D' B' R*D' R' D2 B D L' D' B2 L R2 U2 R'.B2 U'

Due to a shortage of time, nerves and experience with edges insertions the best I could find was .= R U' R U D' F' U F U' D, while IF suggests *=R D R' L B' R' B R L' D', which is just one move better for 31.

 

[irontwig]

Still problems with Frelund's site, here's my solution to #451:

F' U' L B' U2 B2 D B U2 B' D' B R U L D' L U2 R D R D2 R2 D' R' D R D' (28)

F' U' L B' U2 B' [EO+square]
U2.R U L D' L U2 [2x2x3]
R D R D2 R2 D' R' D R D' [Leaving three corners]

Insert at dot: U2 B' D B U2 B' D' B (Three moves cancel)

I had the same problem with Pers site this week (#451).

For 1 hour I had almost the same solve as Tomoaki had, without using Niss and using that same J-perm insertion.

But for his 18th till 24th move I did:

R2 B' D B D' R'


Which results in 25 moves (-;

 

[TheNextFeliks]

I have tried fmc and niss. I got one skeleton with 26 moves. Then I got a pi oll which resulted in a u perm. So 20 move last layer. So 46. Not bad. Do you have any tips for improving ll?

 

[mycube]

how about the solution? ^^

 

[TheNextFeliks]

how about the solution? ^^

Um. No. It was on my computer. Then I had to turn it off so lost it and scramble.

 

[mycube]

so it's nearly impossible to help you with beginner stuff.

 

[TheNextFeliks]

Yeah. I'll do another in a bit and post it.

Hi, I'm now at Helsinki Airport, waiting the next flight to Estonia.
There's a free Wi-fi, nice.

About submission problem at fmc.mustcube.net: now I firmly believe that my expectation is true;
the problem is caused by the missing backslash (\) before prime (') in comments (not solution).
At FMC450 and FMC451, I inserted backslashes manually in the comments (not in solution).
I recommend you to do the same thing until Per addresses this problem and makes some announcement.

Agh, I feel bad about not bringing my cube with me (packing into my suitcase).
I will see your continuation after arrival.

Why are you in Helsinki, if I may ask?

 

[okayama]

Why are you in Helsinki, if I may ask?

I will attend an academic conference held in Tartu, Estonia.
I just transfer at Helsinki, but waiting time is 4 hours, so I just relax and surf the web.

Ok, I'll try that, found a quite lucky 30 mover for the linear scramble.

 

[TheNextFeliks]

My attempt at the new round on fmc.mustcube.net. It is very bad. Tried to do niss in beginning but I am bad at it.

Spoiler: Warning! Round Still Going On

Scramble: D2 U B R D2 F' U L D' B L2 U' L' D2 B2 U2 F D2 U2 F' U' R' D2 F' D2 F' U R2 B2 D'
Solution: B L R D2 U B2 U2 B2 U2 L' U L B' U B U' B' U B R U2 R' U R' F R U2 F' U' F U' R U' R' F D R' B' R' B R2 D' F2 U2
B L R D2 U B2 U2 B2 //XCROSS [8/8]
U2 L' U L //PAIR 2 [4/12]
B' U B U' B' U B //PAIR 3 [7/19]
R U2 R' U R' F R (F' //PAIR 4 [7/26]
F) U2 F' U' F U' (F' //OLL [5/31]
F) R U' R' F D R' B' R' B R2 D' F2 U2 //PLL [13/44]

Tried zz after niss but this was about 5 moves less. Any tips? Not very good. One of first fmc attempts.

 

[irontwig]

Starting with a xcross is a bad idea most of the time. Also you shouldn't use OLL and PLL for LL, but rather trying to leave three corners with a short alg and doing a corner commutator. In fact your LL was just 4 corners and could be could solved with

Spoiler

these two corner comms:
F R' F' L F R F' L'
L' B L F' L' B' L F
U'

Which cancels nicely with your last slot for a 37 move total

I should have done comms. Idk how I forgot. Will do another later. I'll try blockbuilding more.
