[Help Thread] FMC Discussion

What I can tell already: For that 20 move solution I worked with the shortest skeleton I have ever worked with so far.

 

[Memphis3000]

I just submitted my 44 move solution to weekly FMC. Someday I'll catch up to you guys.

Okay maybe not

It's funny how fast things change. Almost a year ago, when Ryan got a 33 PB single at Holy Toledo, I told him that I could never be his nemesis again because of that. Almost six months later, I had a 31 PB single. Now that nemesis thing won't happen because of many other events

You do have a point...

Anyone else having trouble submitting to weekly FMC? I got a page that says "An unhandled exception was thrown by the application."

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

Skeleton:
B F D U' * F2 L ^ F' R D' (U F' U') R' (13) //F2L-1, EO control in brackets
D F2 D' F2 (4) //To L5C

Insertions:
*: F2 R' F L2 F' R F L2 F (9 with 1 cancellation)
^: R2 U' L2 U R2 U' L2 U (8 with no cancellations)

Final:
B F D U' F2 R' F L2 F' R F L2 F' L R2 U' L2 U R2 U' L2 U F' R D' U F' U' R' D F2 D' F2 (33)

I suck at insertions. Insertion finder gave 27 moves. First FMC solve of the year, I think.
I have to say I like my skeleton, at least. I managed to solve F2L-1 at one go by adding a few moves here and there, even managing to EO on the way.
Guess I got lucky.

I just did my first FMC solve, can somebody critique it please? I'll give a walkthrough of my solve.

Inverse: R' U2 B2 R' F2 D L' U2 L2 B2 R2 D F2 U2 R2 L2 B2 L2

2 pairs already made, but I don't like the continuation with either of them.
U L U' // makes 2 pairs
I don't see a nice 2x2x3.

Switch to inverse scramble:
U L' U' + inverse scramble

D2 R2 L2 U' F2 // 2x2x3
x2 // all the edges are oriented but for some reason i ignore that...
U F U2 F U2 F // F2L-1
U F U' F' // EO from this angle because I get 2 CE pairs.

Spoiler

Possible continuation in Heise:
L' R U2 R' U' R U' R' L + double corner twist 27 moves or so.
(for double corner twists I only know the 14 move case and I don't want to do an insertion for this one).

Switch to normal scramble:

Spoiler

Possible continuations in Heise:

y L' U2 L U L' U L y U' L' U2 L + double corner twist = 25 moves without insertion.
Possible continuation as LS+LL:
U L2 U2 L U L' U L2 + triple corner twist = 21 moves without insertion.

It was frustrating that I couldn't get a 3-cycle out of this. Probably because sune doesn't change CP...

Actual continuation (idk how):
U L' U' L F U F' U' = OLL skip. 8 moves + J perm - 1 cancel = 17 moves, the best I can find (and very odd, but I'll take it).

I just did my first FMC solve, can somebody critique it please? I'll give a walkthrough of my solve.

You used NISS for your first FMC solve!? Blimey. That's impressive (to me, anyway). 35 is a very good result for a first solve. One thing: I'd strongly recommend not using rotations in FMC: learn to think "the yellow face is turning clockwise -- that's D" or "blue anti-clockwise ==> B'...". It makes it so much easier to spot when you can cancel moves. Also, it removes the need to hold the cube in a particular orientation.

35 HTM

A start that I would have tried:

D2 F2 U F' R2 F //2x2x3 with wrong pair
D2 L2 //F2L-1 with wrong pair

Wrong pair cases are nice, as when you switch, they become a correct pair in the location of where the wrong pair would have been solved on normal. Unfortunately, this is a bad wrong pair, as you'll see when you switch to inverse. Could have interesting stuff though, the edge orientation is nice.

What i like about the U L U' before the switch is that two pairs appear within a 1x2x3 block, so that means the switch will create pieces for a 1x2x3 block, which you did.

Here's how I would continue (not the best continuations here, I was running into parity everywhere):

N: U L U' //blocks (3/3)
I: D2 R2 L2 U' F2 //2x2x3 (5/8)
D2 R D2 R' D2 //PS F2L-1 (5/13)
N: D B' D B2 D' B' D B D' B D B' //L3C (12/25)

Not in the mood to do insertions myself, so here's IF with a 31 final: http://mf.qiyuuu.com/cube/if/724a611b55f5ef8828e44e877e884de8.cube

Also, I agree -- rotations in FMC solves are hard to follow, both for you and me.

EDIT: Realized I never checked inverse, found this in about 20 minutes once I started doing that:

I: B2 L D2 R2 U' //2x2x2

Looking forward to seeing your solution to the Berkeley competition -- that one was a fun scramble with lots of possibilities.

My Mean of 3 PB (UWR?) from this week:

Spoiler: 20 (David Adam's FMC)

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

EO: F' L2 B
3E6C: U2 R' * L B2

I found this within the first 5 minutes and I saw as well that the edges were in 6 mover position close to the end, so I went for it, trying lots of different insertions. After 40 more minutes I found this:

* = R' F' L2 F R # F' L2 F
# = B' R2 B + F' U2 F
+ = B' R2 B L' B' R2 B L

Solution: F' L2 B U2 R2 F' L2 F R L' B' R2 B L F' U2 L2 F L B2

Spoiler: 22 (1st scramble from German forum)

* = R L' (F' U2 F U F' U F) L R'

Solution: R' U L' D' B2 U2 F U B' R L' F' U2 F U F' U F L R' U' F2

Spoiler: 21 (2nd scramble from German forum)

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

2x2x2: R' * U F' L' + B
2x2x3: R' D2 F # R2
3E4C: D2

* = R L' B2 R' L U2
# = F' L2 F R2 F' L2 F R2
+ = L2 B R2 B' L2 B R2 B'

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

Further, the next solve on a random scramble was another 22, giving me an Average of 5 PB of 21,66.

Current Average of 12 (not sure if PB or not): 26, (30), 27, 25, 27, 27, 26, (20), 22, 21, 22, 26 = 24,9

You used NISS for your first FMC solve!? Blimey. That's impressive (to me, anyway). 35 is a very good result for a first solve.

It makes it so much easier to spot when you can cancel moves. Also, it removes the need to hold the cube in a particular orientation.

Yeah I tried to learn it before I started. Super confusing at first. But if I just used Heise for an hour to find the most efficient solution, that'd be more like preparing a speed BLD or something, not interesting.

As for getting 35, it was actually pretty lucky because the OLL skip saved me like 4 moves.

Yes I was too lazy to do rotationless, I know I should have though haha. I just typed it into an algorithm translator after that and removed them cause it's just my first FMC solve. I'll do another one without rotations.

On a side note, are rotations legal in your solution?

A start that I would have tried:

D2 F2 U F' R2 F //2x2x3 with wrong pair
D2 L2 //F2L-1 with wrong pair

Wrong pair cases are nice, as when you switch, they become a correct pair in the location of where the wrong pair would have been solved on normal. Unfortunately, this is a bad wrong pair, as you'll see when you switch to inverse. Could have interesting stuff though, the edge orientation is nice.

Oh I never considered wrong pairs before switch. I'll try it out.
And pseudo blocks hehe I'll try to get those down but I hate looking at so many different colours LOL. Normally if i see an easy one I'll do it, but I don't have a strong eye for it. Thanks for your feedback though!

Pseudo is super easy if you know NISS - wherever the block is, it will become the correct block once you switch scrambles, you just have to spend a move on the other scramble to move the correct block in.

 

[Smiles]

This was supposed to be my second FMC solve but I gave up after F2L-1 because I was too tired to find the best solution.
Can somebody help me on this one? I'm just really bad at LS+LL.

Normal: R2 U2 F L2 B' D2 B' U2 R2 F2 D R B F2 R B D2 B D2
Inverse: D2 B' D2 B' R' F2 B' R' D' F2 R2 U2 B D2 B L2 F' U2 R2

I: F' D2 R2 B // 3 pairs
N: R B U2 L' U' F' U' // 2x2x3

Here there is a 3 move F2L-1 which cancels into EO for both the normal and the inverse.

Pseudo is super easy if you know NISS - wherever the block is, it will become the correct block once you switch scrambles, you just have to spend a move on the other scramble to move the correct block in.

Yeah I tried a pseudo for this one but i made it a normal block by adding an F move to the end of the 2x2x3 before switching to inverse again just to help me visualize better.

That's ok. Luck plays a large part in FMC...

On a side note, are rotations legal in your solution?

Yes -- they're totally fine. One very small risk is that they'll lead to your solution being mis-counted (happened to me once) in a competition. And of course it adds to the complexity of scribing (by you) and validating (by the judge) the solve.

Solution: R' U L' D' B2 U2 F U B' R L' F' U2 F U F' U F L R' U' F2

Spoiler: 21 (2nd scramble from German forum)

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

2x2x2: R' * U F' L' + B
2x2x3: R' D2 F # R2
3E4C: D2

* = R L' B2 R' L U2
# = F' L2 F R2 F' L2 F R2
+ = L2 B R2 B' L2 B R2 B'

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

Further, the next solve on a random scramble was another 22, giving me an Average of 5 PB of 21,66.

Current Average of 12 (not sure if PB or not): 26, (30), 27, 25, 27, 27, 26, (20), 22, 21, 22, 26 = 24,9

Those skeletons are insanity. I'd never even think to look for that.

Got my first ever sub 30 in the weekly FMC competition this week:

Scramble: D2 L2 U2 L' U2 F2 L U D F2 R2 U' D L2 B' U2 L' U2 L' F
My solution: R U2 R' D2 B' R F2 R' B R F2 U2 L2 F' R' F2 L2 F2 L2 F R2 F' L2 F R2 B U2 L (28)

2X2X2: * D2 R L2 F' R' F2 L2 F' (8/8)
L6C: *** B U2 L (3/11)

Insert at *:

1->2->3: R U2 R' D2 R ** U2 (R' D2) (4/15)

Insert at **:

4->5->6: (R') B' R F2 R' B R F2 (6/21)

Insert at ***:

2->3->6: (F') L2 F R2 F' L2 F R2 (7/28)

I've been spending some time getting used to the ways that multiple insertions interact with each other. So in this solve, I had a single 6-cycle. My first insertion did 1->2->3, and I realised I could insert 4->5->6 into that first comm, since the two comms didn't affect any of the same corners. So my question is, is it ever ok to insert a commutator into another where there is some overlap -- e.g., inserting 3->4->5 into 1->2->3. I can't intuit what effect this kind of thing would have, or is it just unpredictable and therefore not usable?

This has already probably been said before, but a good start for me is to build a 1x2x3 the add the two edges that make it a 2x2x3. Even if it has been used a lot before, I haven't seen it be used lately.
