An MU alg for UB-BD-FU (Optimal, if possible)

I tried to generate some MU algs but acube is failing me.

Anyway, <MU> kind of sucks for this case. I would do:

y [U; M',UR2U'] --> y U M' U R2 U' M U R2 U2

 

[Lucas Garron]

y [U: M',UR2U'] --> y U M' U R2 U' M U R2 U2

A little pedantic, but if you're using my extended notation, then [U: M', UR2U'] (= [U; M', R2]) = [U M' U', U R2 U'] = U M U' U R2 U' U M U' U R2 U' --> identity

(The reason is that it's really common to conjugate an inner part of the commutator; conjugating an entire alg is larger scope, for which the semicolon is a stronger separation: [U; M' ,UR2U'] )

IS there any alg for the Dot case(2 look OLL) quicker than F(RUR'U')F' f(RUR'U')f'? (F' and f' kill me)

(M' U)3 M' U' (M' U)4

Ah, ok. Thanks for the correction.

M U R U R' U' M' R' F R F'

Wrong case man.

You can avoid the dot cases. When you are on your last pair and you don't see any oriented edges, just use the insert R' F R F' and then you will get a better OLL.

This doesn't work for R U R' cases. Well, technically it still does, but it adds extra moves while orienting only two edges, so that you might as well just use a ZBF2L alg.

 

[RyanReese09]

By dot case I assumed he meant the specific OLL case, not just any 2 look dot case.

I did read. I was just saying it was better to use R' F R F' and then you can do whatever you want to do OLL.

:fp he wasn't talking to you. He quoted Ryan's post.

Oh yeah. It's just that people say I don't read well.
Don't facepalm me.

CLEARLY you didn't.

It's just that people say I don't read well.

No idea why...

Thanks ubercuber.



OLL skip algos for these cases -

There was a nice Tperm alg posted a while ago that also flipped the edges involved. Anyone know it?
