12 Edge flip alg?

[Derrick Eide17]

Just posting this because i saw awhile ago on the Blindfold algorithms topic there was an alg that flipped 8 edges. Performed by macky as r R d D (x3) and i thought that was quite cool and useful and was just wondering if anyone has figured out a 12 edge flip alg yet? maybe using combination of 8 edge and a 4 or other possible combos? i have tried but havent found one yet. so anyone know an alg for a 12 edge flip that DOESNT use a combination of two algs?

Johannes showed this alg to me a while ago, and I think it's great!

((r U r' U')*3 (R u R' u')*3 y2)*2

You can replace the y2 with an x2 if you like. Also, you can swap the order of the (r U r' U')*3 and (R u R' u')*3.

In case that's a bit complicated, here it is written out a little more:

(r U r' U')*3 (R u R' u')*3 y2 (r U r' U')*3 (R u R' u')*3 y2

Enjoy!

haha cool man! thanks COOL alg. just a LITTLE too lengthy but i dont mind for now lol. Cool i should have KNOWN someone out there had one lol. maybe we can improve on this? lol

U' R2 U' F2 D' R2 U' B F U2 L' B2 R2 F2 D' U F'
U2 L' R' 20 move optimal solution. But moves are random, hard to do fast

 

[KConny]

(R B R' U) * 5 x2 B F' (R B R' U) * 5 F B' x2

Another one: ((MU)4yx)3.

In case that's a bit complicated, here it is written out a little more:

(r U r' U')*3 (R u R' u')*3 y2 (r U r' U')*3 (R u R' u')*3 y2

Or, with just UDFBRL:
L F L' U' L F L' U' L F L' U' R D B' D' R D B' D' R D B' D' R B R' U' R B R' U' R B R' U' L D F' D' L D F' D' L D F' D'

NIIce some GREAT algs there. A little too long for some but cool. and useful. I have to say i like Johannes the most though

((MU)4yx)3 doesn't seem to work for me. I do

MUMUMUMUyx
MUMUMUMUyx
MUMUMUMUyx

Shouldn't it be ((MU)4yx)6? Which would be:

MUMUMUMUyx
MUMUMUMUyx
MUMUMUMUyx
MUMUMUMUyx
MUMUMUMUyx
MUMUMUMUyx

 

[Derrick Eide17]

hmm are you sure your doing M the right way Arnaud? try M the other way and see what happens. i think i know what ur doing wrong.

 

[Johannes91]

((MU)4yx)3 doesn't seem to work for me. I do

MUMUMUMUyx
MUMUMUMUyx
MUMUMUMUyx

That's correct, and it does work. In UDFBRL:

R L' B R L' D R L' F R L' U
F' B U F' B L F' B D F' B R
U D' R U D' F U D' L U D' B

I was indeed doing the other M.

I always thought MES was like slice-turns of RUF?

 

[Johannes91]

They go to same directions as LDF.

 

[TheBB]

So M, E, S are the same directions as L, D, F but x, y, z are as R, U, F?

That makes no sense.

 

[Pedro]

or you can do ((M' U)*4 x y)*3, if you prefer M' moves (as I do)

 

[Johannes91]

((M' U)*4 x y)*3

Doesn't work, maybe you meant y' instead of y.

 

[AvGalen]

So M, E, S are the same directions as L, D, F but x, y, z are as R, U, F?

That makes no sense.

Indeed! We need a new notation!

I second that! Always had trouble figuring out M, E, S, vs. M', E', S'. Never had trouble with M2, E2, S2 though

 

[Pedro]

((M' U)*4 x y)*3

Doesn't work, maybe you meant y' instead of y.

yeah, you're right

Yes, that was the most confusing thing when i started learning the notation. Even after one year i still have to think "M -> the other way round"

 

[Derrick Eide17]

can anyone find the notations to with M' U' i am AWESOME fast at that i just dont know the x y moves to do to get a 12 edge flip. also YEAH when i first started TRYING to learn stefans M2 method i got SOOO CONFUSED on that whole M, M' thing and i was thinking FOREVER it just DOESNT MAKE SENSE. so i definetly agree we should change this.
