[Help Thread] FMC Discussion

[irontwig]

Isn't that "domino method" very similar to HTA?

Yes, but less rigid. You can also reduce it by block building (e.g. oriented 2x2x3) and finish EO later. One other option is to ignore some corners' orientations and make a more conventional skeleton, although then you're pretty close the more normal EO-first approach.

First solve in over 2 years

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

Solution: B' R D2 L U L' D' L U' L2 D L D2 R2 B' R B2 U R2 U' B2 F' U F U2 R F' R D2 B2 (30)

Process:

Start with inverse scramble: F' U2 R' B' U' F2 D L D' R2 F' R2 B2 L2 U2 R2 D2 F' D2 B'

2x2x2: B2 D2 R' F (4|4)

2x2x3: R' U2 F' U' F (5|9)

F2L-1: B2 U R2 U' (4|13)

F2L: B2 R' B R2 (4|17)

3 Corners: D2 L' D' L* D' R' B (7|24)

Insert (L U L', D) at the * to solve and cancel 2 moves, resulting in 30 moves total.

Notes: It was kind of an easy scramble with an okay result. I'm certain there are better finishes to my start but I am a lot slower than I used to be. I will try to do at least one a week to shake the dust off.

Anyone ever tried SQ1 FMC? I say each / move is one move, and U and D face moves don't count towards the result.
God's number for SQ1 is 13 by that rule, so can anyone achieve this?
(my best solve was 27 moves)

I also found 27-move solution, but different skeleton and insertion. Plain one.
But inserting 3C and 4E in 10 moves is just crazy!

Nice!

Yeah, when I found I had the 3 twisted corners and 3 edge cycle, I knew there would be a few ways to solve them using sunes and fat sunes. Thankfully I was lucky enough to find a one move setup to fat antisune at the start of the skeleton

Okay, so I'm new to fmc and this was my first ever attempt. I don't know any fmc methods so I just used cfop.

Try to block-build more. Learn how to NISS

 

[gyroninja]

I've had a pb for a few months it had a short move count. About a month ago I realized the zbll for the case was just a back antisune. I've pieced together the solve and removed moves that would cancel and got a solution of 19HTM. Since I'm new to the forums I figured I should share it here.

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

Scramble had eo completed.

Original Solve
U2 D' L' D' L2 U2 L2 R' // XXXEOLine
R' U' R U' R' U' R // Right Block
U R U R' U R U2 R' // COLL - Sune
U M2 U' M U2 M' U' M2 U // EPLL - U

With Easy LL
U2 D' L' D' L2 U2 L2 R' // XXXEOLine
R' U' R U' R' U' R // Right Block
R' U2 R U R' U R U' // ZBLL - Sune

Then you just cancel moves out.

37 moves with CFOP is very good! To improve, I definitely recommend reading porkynator's guide. It's very good.

I was analyzing Keaton's 5.09 scramble for fmc and found this-

Scramble: D2 B2 F R2 U2 B R D' L' U2 L' D' B' L' D2 B2 L
Skeleton: R F L B' D' F'

Explanation:
Premove: F2
2x2x2 with EO: R F L B' D' F //6 corners with 1 twisted and 3 edges

Couldn't do good insertions. Can anyone do the insertions? Its 4 insertions but IF doesn't do it

Also found 16 to 5 edges
Skeleton:R F L B' D2 F D' F' D' L' D L' F' B D2 B'

Not bad! Just remember there's always NISS to play with and you probably should have used insertions instead of cancelled LL algs.

I am by no means an FMC solver, but I was interested if anyone has tried the following. FMCing a 2x2, i.e. getting optimal solutions. If anyone has done this (especially top FMC solvers) or wants to give it a go, let me know how hard it is finding an optimal solution. I myself have written a 2x2 optimal solver on the computer, and for the longest scrambles it takes a reasonable amount of computer work.

 

[G2013]

I have done something like that (I'm not a top FMCer and my PB is only 27 moves, but I have done it)

I posted my solutions last year in this thread:

[tx789]

I got another sub 40 FMC today. I'm practicing for NZ Nationals in just under two weeks. My very, very happy with the finish on this solve.
