The FMC thread

[irontwig]

I was wondering if you guys could help me out with my FMC 'method'.
I am using classic Roux, no tricks or shortcuts and im noticing that my LSE is horrible. (usually the step with most moves)
Is there another way I can FMC using the 2 roux blocks? Or maybe just the FB?

Here's decent attempt:

Most of the time Snyder/Heise produces better solutions though.

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

On inverse
U2 B D' B L D' L2 B2 // 2x2x3 (8)
U' R U2 F' U' // F2L-1 (13)

On normal
U F U2 R' U B2 L2 D L' B' D B' U2 // Premoves (13)
R2 B U F U' F' B' R2 // F2L (8+13)
F // Align edges (9+13)

R2 B @ U F U' F' B' R2 F U F U2 R' + U B2 L2 D L' B' D B' U2
@ = F' D' F U F' D F U' (3 cancelled)
+ = R' D R U2 R' D' R U2 (2 cancelled)
Final: R2 B F' D' F U F' D F2 U' F' B' R2 F U F U2 R2 D R U2 R' D' R U' B2 L2 D L' B' D B' U2 (33)

Could've been much better, but I found the second insertion with 2 minutes left
Although I'm very happy that I found those insertions...I know all optimal L4C cases and I know that case is 13 turns (and insertions with cancellations is 11, so took 2 turns out)

My new FMC PB! Tell me what you guys think!
Scramble from weekly comp 32
F' D2 R' U D' F' R2 L' B' R2 B2 U2 R2 D' R2 U2 F2 U B2 D

U B R F U' //FB
z2y' r' U' R U r2 U R' U' R2 B' R' B //NonMatching SB, with Sexy insert
M' U2 M U' M U' M' U' r R //2.5 Look LSE with several cancellations
alg.garron

Freakin 27 MOVES!!!! I cant believe it.
This is more than 10 moves less than my previous PB.

FMC is measured in HTM, so that's actually 31 moves

Shhhhhhhhh! Im counting it as 27.

Can anyone open insertion finder now?
I just finished my FMC attempt in Per's website and want to check whether my insertion is optimal or not.
But the server seems goes off.

here is my attempt on classic scramble
(Don't open if you want to try)

Spoiler:

square: U B' L
2x2x3: D R U' B2 L
F2L-1: D B2 D' B
F2L: D' L' F' D' F
OLL: B' * L' F L' F' L2 B
Insert at *: F' R' F L2 F' R F L2
29 moves

Is the insertion efficient?

did a FMC-attempt in a facebook-competition and got a ne PB
D' L F2 B2 U F' U R' F2 B2 D B2 U B2 D F2 D2 B2 L2
L2 B2 D2 F2 D' B2 U' B2 D' B2 F2 R U' F U' B2 F2 L' D

inv: Premove: L2
L B2 – 2x2x2 [3/3]
D' F' D U F2 – F2L-2 [5/8]
B' R2 F R2 B' – F2L-1 [5/13]
D R D' – EO [3/16]

L5C:
L . B2 D' F' D U : F2 B' R2 F R2 B D R D' L2
. = D' F' D B2 D' F D B2 [8-8/16]
: = D' F' U2 F D F' U2 F [8-1/23]

Inverse Solution:
L D' F' D B2 U D' F' U2 F D F' U2 F' B' R2 F R2 B D R D' L2

Final Solution:
L2 D R' D' B' R2 F' R2 B F U2 F D' F' U2 F D U' B2 D' F D L' – 23 Moves

can't check for optimal insertions because the IF is down but 8 move cancellation for the first insertion is great!

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

Premove = R'
U' F L B U' D2 L' U D' L U' B2 // (12) F2L -1 slot
R' U R B U' // (17) requires only 2-edge 2-corner swap
B' U2 R' // (20) (almost) solved

I can't find how to swap the 4 pieces. Could you help me?
