Solutions for my 22.00 WR mean (16, 26, 24) at FMC 2019:

1.
Scramble: R' U' F D2 L2 F R2 U2 R2 B D2 L B2 D' B2 L' R' B D2 B U2 L U2 R' U' F
Solution: D2 F' D2 U2 F' L2 D R2 D B2 F L2 R' F' D U' (16 - optimal!)
I have found a couple of interesting EOs on normal scramble, which looked like they could lead to some nice domino solves. But I decided to switch immediately to check the inverse as well. DR + easy corners = insert right away!

(U D' F R) //EO (4/4)
(L2 F' B2 U' B2 U' * ) //DR (6/10)
(R2 B + F D2) //5e (4/14)

* = U D' F2 D U' # R2 //2e2e (6-2/16)
+ = E2 //Leaves 4x (x = "centers") (2/18)
# = E M2 E' M2 (2)

First solution: D2 F' D2 U2 F' L2 R2 {U' D B2 D B2 U} B2 F L2 R' F' D U' (20)
Replace {U' D B2 D B2 U} with R2 D R2 D, which also cancels 2 with the previous move (-6+4-2)

I don't what to say about this... a really advanced solve with lot of luck involved. I was shaking so much after finding the 16 that I had troubles writing down the first move.

2.
Scramble: R' U' F D2 L2 B F L2 B D2 F L D R2 U2 B L R2 U' R2 U B U2 R' U' F
Solution: U2 R' L B' R2 B L2 B' R2 B U L2 R' D2 R' D' L' D2 L D B2 F2 R' F' L' R (26)
(R' L F) //EO (3/3)
(R F2) U2 //2 squares (3/6)
R' L' * U R2 L2 //223 + pairs (5/11)
R D2 R' //Pseudo F2L-1 (3-1/13)
D' L' D2 L D B2 //3C (6/19)

* = L2 B' R2 B L2 B' R2 B (7)

Kinda unlucky insertion, but this evens out with the kinda lucky insertion on the last solve :)

3.
Scramble: R' U' F U2 R2 D B2 D' R2 B2 L2 F' D R2 B D' R D2 F U2 B' U' R' U' F
Solution: F2 R' D R D2 L2 F2 B2 L F L' B2 L F L' U' R2 B2 L' B' R U R L (24)
(L' R' U' R' B) //EO (5/5)
(L B2) F2 //2 squares (3/8)
(R2 U) //222 (2/10)
(L F2 L' F2 L2) //F2L-1 (5/15)
(D2 R' D' R) //3C (4/19)

Skeleton (on normal): F2 R' D R D2 L2 F2 * L F2 L' U' R2 B2 L' B' R U R L
* = B2 L F L' B2 L F' L' (5)

I have found this quite quickly, but it looks like there should be something better.. I had another 24 as well with a very similar skeleton (same 3 corners left):

(L' R' U' R' B) //EO (5/5)
(L B2) F2 //2 squares (3/8)
(R2 U) //222 (2/10)
(L F2 R F2 R2 D2 L D' R)

A few thoughts.
* I am obviously very happy. I have put a lot of effort in FMC lately (practicing almost every day after hours of math research/classes/teaching is really tiring!). it's nice to see hard work paying of.
* I totally was not expecting this. I thought that it was possible we could never see an official 16, and the mo3 is very low too.
* I am sorry for Mark, he only got to keep his records for a couple of weeks...

EDIT: I explain my solves in this video.

@porkynator Massive congratulations man, you deserve this so much!
@Cale S that last solve was legend haha, but I would have never imagined that one day a sub 24 mean wouldn't podium :eek: Congratulations!
I'll post my last two solves here soon

Did anyone find the 11 to good 7c on the last one?

1: DNF
EOs were very good on this one, couldn't find anything good in time though :/

I lost an 11 move Domino because i wrote everything under the wrong EO :p Here is the actual reduction:
D' F B' R'//EO
(F2 B' D2 F' D B' D')//DR
Doesn't look very good to me, can someone help?

2: 27
(R' L F)//EO
(R F2)//sq
(L2 B2)//123
L' R' (1) U R2//223
L' D' L2 D' L'//Good 6C in 16

(1)= L D L' (2) U2 L D' L' U2 (8-3=5)
(2)= B' L F' L' B L F L' (8-2=6)

Comments: Again a very nice scramble for EOs. Got slightly lucky with the good 6C. Optimal too :D

3: 27
F2 R'//EO
(U' L2 D2 F)//ps222+ lots of edges
(D' B U2 B' U2)//Good 7C in 11

F2 R' U2 B U2 (2) B' D F' D2 (1) L2 U

(1)= D2 F' U2 F D2 F' U2 F (8-3=5)
(2)= U B U' F' U B' (3) U' F (8-1=7) :(
(3)= B2 U' F' U B2 U F U' (8-4=4) :D

Comments: wow. I freaked out when I couldn't find anything better than a 1 cancel after the first insertion but then I got lucky on the third :DAlso optimal.

Oh well, I'll get a mean next time lol

also 19.67 potential mean!!!!!!!!!!!

23.00 Mean from FMC 2019! 21, 26, 22

#1: 21

R' U' F D2 L2 F R2 U2 R2 B D2 L B2 D' B2 L' R' B D2 B U2 L U2 R' U' F
(D' U F R) //EO
(L2 B2 F' U' B2 U) //domino
(R2 F B D2) //14 to 5e

Skeleton: D2 B' F' * R2 U B2 U F B2 L2 R' F' U' D
*: B U2 D2 F U D' L2 U D' (2 cancel)

Solution: D2 F' U2 D2 F U D' L2 U D' R2 U B2 U F B2 L2 R' F' U' D (21)

Notes: The same skeleton as Sebastiano, not particularly annoyed that I didn't find the 16 though, I would never have tried those insertions after finding the 9-2 !

#2: 26
R' U' F D2 L2 B F L2 B D2 F L D R2 U2 B L R2 U' R2 U B U2 R' U' F
(L R' F) //EO
(R F2 D' B2 L') //pseudo 223 + square
U2 R D' R F2 R' F2 //pseudo F2L-1
U' R' U //pseudo F2L
F R2 F' R' F2 L F' R' F L' //finish

Solution: U2 R D' R F2 R' F2 U' R' U F R2 F' R' F2 L F' R' F B2 D F2 R' F' R L' (26)

Notes: I feel like this solution is pretty lucky, I had a 16 to 5e from the same start and messed around with some slices but could only get 28.
#3: 22

R' U' F U2 R2 D B2 D' R2 B2 L2 F' D R2 B D' R D2 F U2 B' U' R' U' F
L R2 D B' //EO
L' U2 L2 U' R U' //domino
R' U2 R ^ U2 R //15 to 2e2e + 3e

^: R B2 U2 F2 L @ D2 F2 U2 (3 cancel)
@: L2 B2 L2 D2 F2 R2 F2 D2 (6 cancel)

Solution: L R2 D B' L' U2 L2 U' R U' R' U2 R2 B2 U2 F2 L' B2 L2 D2 F2 R' (22)

Notes: Lots of luck involved in the insertion here, but nice that it was another domino solve :)

@Cale S not strictly related to your solves, but I noticed you have been doing a lot of domino practice lately. Do you think it may be viable as an FMC method by itself, replacing the "mix of everything one knows" that almost everyone is using now? Do you think one can consistently average say sub27 within time limit? Or even less maybe?

I know Cale is doing a lot of that stuff, but also I know @WoowyBaby is doing a ton of Domino-related ideas. I would ask them both, Woowy just got a PB 22.33 mean on the speedsolving weekly competitions where 2 of the 3 solves used a variant of domino.

While practicing for this comp I did a session of attempts using only domino and got a 24.95 avg25, so I think domino only as a method can consistently average sub-27 for sure, and maybe even sub-26 or sub-25.

The main thing that really improved my finishes recently was realizing how effective it is to solve corners, then insert slices and edge algs to finish.

Congratulations to everyone at FMC 2019!
I would’ve never known official 16 single would happen, let alone so soon! And then we got WR mean of 22.00! @porkynator your hard work of FMC over the years really pays off! I bet you’re very happy about your results!
And then the fact that there were 6 people with a sub 26 mean and ~20 people with a sub 28 mean is just amazing!
FMC 2019 was a very successful competition. Good job guys!

@ImmolatedMarmoset I’m sorry, don’t look at me. I’ve been cheating. I take however much time I’d like not 1hr, and I even use cube explorer to find a few moves for my solution which is even worse. I kinda want to delete cheated results. I’m going to follow the rules. I still invest a lot of time into learning FMC techniques and thats my excuse for myself, but no excuse is good. Some of my results are a mix of real and fake, so it's hard to clear everything, so the safe bet is to not trust anything I've done before today. I'm sorry I’ve done this.

@porkynator I don’t know if straight Domino would always give you great results within an hour, but I do know that doing Domino but leaving some edges to be inserted with a 2e2e or 3cycle is really quite nice and could give you better results with less time.

My much, much worse FMC solutions:

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

x2 // Being bad
R D' R L' F' // EO
R' D' R D' R' L' D2 // Line + some blocks
U F2 D R2 D' F2 // LF F2L insert + preserve blocks
R2 U2 R2 U R' // Pseudo block
U2 R' U' R U' R' U2 R2 U2 R' U' R U' // 2GLL that cancels into the pseudo block

Final: x2 R D' R L' F' R' D' R D' R' L' D2 U F2 D R2 D' F2 R2 U2 R2 U R' U2 R' U' R U' R' U2 R2 U2 R' U' R U'

36

I found this pretty quickly and wasn't able to do anything else with it.

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

U2 R' U2 R2 F R // 2x2
y2 // Being bad
U R U2 F R2 // 2x2x3
U R' F2 R F // F2L-1
U2 R' U2 R2 U R2 U R2 // F2L+cancelling into ZBLL
B2 R F2 R' B2 R F2 R2 U' // ZBLL

Final: U2 R' U2 R2 F R y2 U R U2 F R2 U R' F2 R F U2 R' U2 R2 U R2 U R2 B2 R F2 R' B2 R F2 R2 U'

33

I just realized now that the ZBLL was just 3c and I probably could have looked for an insertion, especially since I found this within 10 minutes. But, I've never practiced that and it already cancelled a move so ¯\_(ツ)_/¯.


I also found this 10 minutes after the other and spent the rest of the solve trying to look for an insertion, but couldn't find anything that would save a move.

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

U2 R F R2 U2 R' // 2x2
y2 // Being bad
F' R' F R' U' R' D' F' D F2 // 2x2x3
R U R' U' R U2 R U' // Magic - 24 to 3c
F' L F' R2 F L' F' R2 F2 // ZBLL

Not final: U2 R F R2 U2 R' y2 F' R' F R' U' R' D' F' D F2 R U R' U' R U2 R U' F' L F' R2 F L' F' R2 F2

33

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

x2 // Being bad
L R2 U F R' U R' F2 // D2 away from line + 2 2x2 blocks kinda
R L D2 R' // Get blocks in order
D U2 L' U' L U L' U' L U D' // Keyhole F2L-1
R' U R2 // Last pair + cancel into 2GLL
U2 R2 U' R2 U' R' U R' U R // 2GLL

Final: x2 L R2 U F R' U R' F2 R L D2 R' D U2 L' U' L U L' U' L U D' R' U R2 U2 R2 U' R2 U' R' U R' U R

36

This took a lot more work to find. Getting the blocks to work and lead to anything decent took most of the time and I found the end with about 15 to go.

but

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

z2 // Being bad
U D2 R F // EO
L U' L F2 U' R2 // XXEOLine
U' R U R' // Insert
L U' L' U' L U // Insert + get a zbll that I can figure out
F U2 F' U2 F U' F' U' F U F' U L' U2 // H ZBLL

Not final: z2 U D2 R F L U' L F2 U' R2 U' R U R' L U' L' U' L U F U2 F' U2 F U' F' U' F U F' U L' U2

34

I found this end about 15 minutes after the attempt ended. I hadn't even looked at other EOs cuz I'm bad.

I don't know the adj swap H ZBLLs, but I know full Pi, and the inverse of the adj H sets are Pi algs so I knew would be able to solve it. I figured out which alg it was and did that. Rip sub 35 mean.

What a great competition.

@ImmolatedMarmoset I’m sorry, don’t look at me. I'm a cheater. I take however much time I’d like, not 1 hour band I might use the forbidden cube explorer to find a few moves for my solution. I’m going to delete those cheated results. I’m going to follow the rules. I still invest a lot of time into learning FMC techniques and thats my excuse for myself, but no excuse is good. Lots of my results are a mix of real and fake, so it's hard to clear everything, so the safe bet is to not trust anything I've done before today. Once you see perhaps 28ish means you’ll know it’s me being real, even though they might look similar to my illegitimate ones. I'm sorry I’ve done this.

@porkynator I don’t know if straight Domino would always give you great results within an hour, but I do know that doing Domino but leaving some edges to be inserted with a 2e2e or 3cycle is really quite nice and could give you better results with less time. (I might edit in an example here)
Ok! Either way, I know you’ve been doing a lot with that stuff, and I still think it’s interesting to point out.

Solutions for my 22.00 WR mean (16, 26, 24) at FMC 2019:

1.
Scramble: R' U' F D2 L2 F R2 U2 R2 B D2 L B2 D' B2 L' R' B D2 B U2 L U2 R' U' F
Solution: D2 F' D2 U2 F' L2 D R2 D B2 F L2 R' F' D U' (16 - optimal!)

Well done Sebastiano you deserve both world records!
I found U D' F R on inverse toom but didn't spend much time on it because all EO's looked interesting, appreantly I picked up the wrong one and I'm not good in domino solves!

I was kind of wondering about some of your competition solutions. Didn't want to say too much because they were all valid explanations and had some kind of interesting, novel approaches, but ones that I was skeptical could be done in 1hr. Very cool that you're practicing DR stuff, but definitely good to keep that to non-competition scrambles. :)

I'm just wondering, are there methods for Domino Reduction finishes? Or is it just try some blockbuilding, corner placement?
Yes! There’s a couple of methods:

There’s Half-Turn-Only Reduction, where you reduce the cube further to a [R2,L2,U2,D2,F2,B2] state, then it’s usually easy to finish from there. This is what Thistlewaite’s algorithm does.

Then there’s also solving Corners + as many edges as you can, and then inserting slices and 2e2e and 3e algs into your skeleton. This is what Cale Schoon does very often and many other people have had great results with this. I’d say this is a lot more popular than HTOR.

Hope this answered your question!

I've been doing a bunch of practice solves, and I just can't break the sub 30 barrier.

Here's my latest one, I got pretty close but couldn't find a good insertion:

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

R2 U' L U' F2 //2x2x2

Skeleton: R2 U' L U' F2 B' L2 B2 L B L' U L U' F' L F U L' U' L2 B' U2 B U' *
Insertion: * U' B2 U F U' B2 U F'

32 moves
Couldn't find a better insertion with more than 1 move cancel. Checked insertion finder later and it also only gave 1 move cancels. Unlucky.

I saw that a lot of good fmc solves almost always begin with EO. Is that just a generally good way to start the solve instead of immediately looking for blocks?

Here's a really, really, quick way to get to Domino Reduction but is often pretty inefficent.
Easy to understand but not great results.

Here's some examples-

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

R' L B' // EO
R' D U' L U2 L // CO
D2 U R U2 D2 L // E-edges
15 move DR found in 2 mins

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

F' D U2 L F' // EO
R U R' D2 R // CO
U F2 D L U2 D2 R // E-edges
17 move DR found in 1.5 mins

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

R' U2 D' B R' // EO
F D' F' U F // CO
U D2 B U2 D2 F // E-edges
16 move DR found in 2 mins

Obviously 16 moves for Domino Reduction isn't great, 10 moves is something really great, but the whole point of this is to do DR quick with reasonable efficiency, so maybe if you're running out of time and you want something decent that's not a DNF or something.
However, if you spend more than 2 minutes, maybe 5 or 6 minutes using this you could easily get 13-14 move DR's with this.

Here's an unrelated but still interesting fact about Domino/Kociemba- The first phase takes 9.53 moves on average optimally, and the second takes 13.28 moves. So an initial computer solution using Domino/Kociemba is around 23 moves, but of course solving phase 1 slightly suboptimally to result in a very short phase 2 is the reason Cube Explorer can yield 19 move solutions using it within seconds. Alright you probably don't care too much so move your eyes to the next paragraph below lol.

By the way, when doing the final move of EO see which choice of F vs F' (or whatever move) gets you better CO, and similarily, the final move of CO can either be a clockwise or counterclockwise turn, so see which way makes a better E-edges case. Generally you want two E-edges already in, because the E-edge algorithm, R E2 R', puts in 2 E-edges. Having an odd number of edges in usually sucks. (although R U M2 U' R' isn't that bad)

But just know that the most efficient way to do Domino is to setup to a single move. But then again that requires more mental power and a lot more time.
But I know it's better.
So basically I'm just offering a worse lazy alternative xD

Now I'll try to find a very easy way to get from Domino to solved with reasonable efficiency so perhaps you can find a sub-40 move Domino solution in 5 minutes or so.
But just remember, complex and difficult to conceptualize solutions are generally more efficient, so don't expect to get world class results with a simple method like this.
I'll post again once I find something for phase 2, so stay tuned or whatever!

The other two seem to work fine, but this first one seems to not work right on the CO. Typo somewhere? Or am I doing it wrong?
