Inverse,

Got a 22 on this week's weekly FMC.
I'll edit it into this post when ll be less lazy

 

[Attila]

previous weekly FMC:

R2 B' R2 U2 D' B2 L' U2 D2 B R B' L' R D U2 R' D' B2 U2

My solution (DNF-ed in 1 hr limit):

L2 D R' U2 R' D2 F' R U2 D2 L' F2 L2 U2 B' U L R' F U' D' 21 moves

L2 D R' U2 R' orient corners and 5 edges,
(U D F' R L' U) more 1 edge + orient all edges,
D2 F'-R U2 D2 L'- F2 L2 U2 B' U2 domino solution with inserted -R U2 D2 L'-

Man u were so close to ruining my first win. By ruin I mean completely obliterate it

If you get a H perm at the end of a skeleton, it's better most of the time to just use the optimal H perm alg (R2 S2 R2 U' R2 S2 R2 or something similar) than to do 2 insertions right? Unless I'm underestimating the comms... idk

I'd try to insert R2 U2 R2 U2 R2 U2 or M2 U2 M2 U2 (Maybe with some setup moves)
I haven't thought about it too much, but doing 2 insertions seems not worth it.

If you treat it as AB4C then you have to cancel more than 6 moves (or 5 depending on AUF) otherwise it's better to just use the optimal alg.

But doing it your way is better though

Yeah I've inserted those stuff twice before. Pretty useful

 

[EMI]

I guess most of the time you would cancel into the R2 of the H-perm as well, so it's even better.
Also it seems unlikely that you would find 6-move insertions for both 3-cycles.

a few ways to do it

R2 S2 R2 U' R2 S2 R2 U
R L U2 R' L' F' B' U2 B F
insert R2 U2 R2 U2 R2 U2
insert M2 U2 M2 U2
2 edge comms
insert a U2 and then L4C insertions

with the first two you can almost always cancel a few moves

A nice linear FMC single ending with R2 U2 R2 U2 R2, just like the 19 WR



except this is legit

Wow. FMC is so frustrating. I'm trying. I really am. I feel like there has to be a good block you could do with this scramble, but the best 2x2 I can find is 7 moves. AHHH!

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

for the record, my 2x2 is U D L' B D' B' U

I feel like I'm close to understanding how to do FMC right, but I'm not there yet. And it's frustrating.

Well done, exciting enough I found another 20-move solution for that same scramble (same competitio)n. You can check next sunday....

Moves in brackets on inverse. I could only find a 7 mover on normal, sorry if you don't understand NISS

(R2 D2 L U' F L) - 6 moves

(F2 L' B' U') U - 5 moves
