Blindsolving Discussion and Help

I don't know this number. I'm thinking that the calculation would be quite a bit more difficult to do than a very simple lines like this. There will be many isomorphic cases for each true possible case. Richard Carr studied the corner orientations in quite a lot of depth a couple years ago. If anyone would know the answer to this fairly definitively, then he would. I would try to send him an e-mail, he's a member of this forum.

(Thanks!)

What camera angle should I use for film multi attempts? I'm tryign to get an angle sorted out now.

Can anyone take the time to go through a 4x4 scramble with me and make sure I'm doing stuff right via skype?

I'll work through a solve with you, but I don't have skype capability right now. Facebook? PMs? Just post the scramble in the Big cubes BLD thread and explain what you are doing/looking at for your solve? What would work best if Skype is not available?

 

[lucarubik]

does anyone have any idea about how to solve UB FR BR with RU turns?

R U' R U R' U' R' U' R' U R U2 R'
Do you like this alg or is it too long?

 

[lucarubik]

Isnt this a Uperm?
aint bad but I make UB UL DR and UB UR DR with this idea this would be too much
thanks anyway

Facebook instant messaging would work best since it's the closest thing. If possible, and you have free time tonight, try to be on facebook around 9 eastern (if this doesn't work, anytime 9pm-1 in the morning is good for me) and I'll go through a scramble with you.

For MultiBLD, can you solve all corners on all cubes, then all edges, or do you have to solve it a cube at a time?

 

[RyanReese09]

You can do all corners firstif you wish. Doesn't matter. You can do 1 comm at a time per cube if you wish.

 

[Xishem]

Commutators are the fastest execution method for corners, yes.

Debatable.

Then continue to debate. I want to see what your case is.

::EDIT:: Actually, lets move it to the random BLD cubing discussion. I still want to see what makes you think it's not the fastest, though.

It may be the fastest, most practical way to solve the corners, but maybe not the fastest.

i.e., ortega, optimal solving, etc.

Yes, I realize that ortega isn't used for 3bld, but it is an execution method for corners.

Edit: Also, since he was almost certainly implying 3-cycle commutators, what about 5- and 7-cycle comms? 2 swaps?

 

[uberCuber]

lol

ortega, optimal solving

I would love to see you figure out a way to make ortega or any 2x2 speedsolving method usable for 3bld.
Or a way to figure out an optimal solution to corners in a few seconds, and in such a way that edges would still be easy to figure out from there.

Also, since he was almost certainly implying 3-cycle commutators, what about 5- and 7-cycle comms? 2 swaps?

Please develop a way to solve 5-cycles that is as complete as BH is for 3-cycles. I am not saying it is impossible to solve some 5-cycles intuitively (e.g. X Y X' Z Y' Z') but remember the amount of non-isomorphic 3-cycle cases for BH, and think how many more it would be for 5-cycles.

 

[RyanReese09]

It's the fastest way known that is an actual method. You're just trying to name crap that isn't a method but if it were it would be faster. In reality, the fastest method would be to 1alg the corners and preserve the rest. That would be the fastest (assuming you can recall the alg)

Down to earth-comms are the fastest.

 

[minime12358]

Yes.

Now, how do you do 5 cycles? P

Edit1: After playing around with cube explorer, its interesting as 5 cycles do seem to take some sort of form that I have yet to figure out
Edit2: For instance : U' D' B' D R' D' R B U R' D R

 

[uberCuber]

as was in my above post, X Y X' Z Y' Z' is one way. Got it from Kirjava

Midge algs for M2 for 5bld?
I know the BD and FU algs already, and obviously UB. Just need the M' U2 M' U2 and inverse comms. Since those aren't centersafe.

 

[minime12358]

Oh! Thanks

So U' D' B' D R' D' R B U R' D R

X Y X' Z Y' Z'

U' (D' B' D) ( R' D' R) (B) (U) (R' D R)

I see A B C D A' C' ?
A = U'
B = D' B' D
C = R' D' R
D = B

Or is this just simplified, were as X Y X' Z Y' Z' is just as close as it is easy to get?

I could generate them if you would like.
Cube Explorer says that it could take up to 4 hours to create the table for center twists though.

 

[RyanReese09]

Erm, they should exist. Anyone who does M2 for midges should have *some* way of handling them.

 

[minime12358]

K, well worse comes to worst, message me; the table is being generated

Edit: Woh O.o so much for 4 hours, it looks like it is half way done.
