Random Blindfold Cubing Discussion

Completed my list of speed-optimized 3-cycles for wings.

It is written with my lettering scheme so that I could show you my letter pair images and words used for memo. There is a breakdown of my lettering scheme on both pages and there are filters so you can look up algorithms regarding specific wings.

There is also a comments section - it will usually give advice on how to work out the advanced r2 algorithm, give an alternate alg or give you a better alg which I've only thought of after writing.

There are BOUND to be mistakes, although I have checked over already. Please point them out so I can correct it quickly.

LOL BJ. This is a masterpiece, bookmarked. Thanks for compiling this.

Edit: Is that possible to download so that we can change the lettering scheme to our own ones for easier reference?

I'm not sure. I "published" it on Google Documents which I'm not familiar with and it doesn't copy and paste well back into Excel. PM me your email and I'll send you a copy!

And thanks for the kind words!
 
Here are the maximum number of centres solved in 20,000 scrambles for 4bld:
Centres/Occurences/Percentage
<5 0 0.00%
5 22 0.11%
6 1565 7.83%
7 6173 30.87%
8 6671 33.36%
9 3596 17.98%
10 1396 6.98%
11 429 2.15%
12 117 0.59%
13 22 0.11%
14 8 0.04%
15 0 0.00%
16 0 0.00%
17 1 0.01%
>17 0 0.00%

Interesting.

Does the fact you calculate something for 4x4 bld mean that you are back to blinds? :)

No. I still enjoy talking and thinking about bigblds but am not tempted to solve.
I just enjoy excel a bit too much sometimes

EDIT: Interestingly, after my 4bld WR I said that it was a nice scramble, but maybe I would expect one that good in the 3 available scrambles at that comp. Indeed it had 9 centres solved and the probability of >=9 centres seems to be almost 30% so I was around the right area.

Debating doing a tutorial for a TuRBo edges method for a DF buffer. It's not a new idea, but I can't see any tutorials on YouTube and it may be useful for people who want to learn comms or even people wanting to learn to BLD from scratch.

DF -> UL -> UR - U M' U2 M U
DF -> UR -> UL - U' M' U2 M U'
DF -> LU -> RU - y' M D' M' [U2] M D M' [U2] y
DF -> RU -> LU - y' [U2] M D' M' [U2] M D M' y
DF -> UL -> RU - y U' L2 U [M'] U' L2 U [M] y'
DF -> RU -> UL - y [M'] U' L2 U [M] U' L2 U y'
DF -> LU -> UR - y' [M'] U R2 U' [M] U R2 U' y
DF -> UR -> LU - y' U R2 U' [M'] U R2 U' [M] y

Pros would be the low move counts for each alg, slightly more freedom with your set up moves because you can do U moves without moving your buffer piece around, and it's a start for people who want to learn about commutators because most of the algs are indeed comms. S'pose they'd be easy to learn too - just changing the position of the [interchange] gives the other alg.

Cons would be the U M' U2 M U not being center safe so it can't be used for midges (unless centers are solved first) and the rotations needed for the majority.

I still using this algo

DF-UL-UR = U M’ U2 M U
DF-UR-UL = U’ M’ U2 M U’
DF-UL-RU = y U’ L2 U M’ U’ L2 U M y’
DF-RU-UL = y M’ U’ L2 U M U’ L2 U y’
DF-UR-LU = y’ U R2 U’ M’ U R2 U’ M y
DF-LU-UR = y’ M’ U R2 U’ M U R2 U’ y
DF-LU-RU = M U’ M U2 M’ U’ M’
DF-RU-LU = M U M U2 M’ U M’

I liked TuRBo but I also like the UF buffer. Another point is with the targets on 2 layers, you are forced to rotate instead of using an AUF. Good luck anyway. It could help people using M2
 
Wasn't sure where to post this:

I have just started learning old Pochmann method. I was practicing solving without memo to get used to the algs etc. However, I was deliberately not dealing with the parity problem. I got to a stage where I was completed except two corners were not orientated correctly.

I know this is probably explained in multiple places but how can everything be correct except two corners? I thought cycles on a cube were always in threes.

Misoriented pieces are not cycles. You can:
Flip an even number of edges
Twist 3 corners in the same direction
Twist 2 corners in opposite directions

So is it possible to have any number of misoriented pieces? For example, would it be possible to have one misoriented piece?
 
I know no one in the world has tired this before but i want to try this and hoppefully i will be the first. I want to try every wca event blind in relay by before school starts back up in 2014 might be before that but this is a lot of work so im giving myself a lot of time, im not doing feet and fewest moves sorry :(. Im trying 6BLD next week, I know how to solve 7BLD I just haven't tired it. I only need to learn megaminx and square-1 which will be the hardest to learn. Then re-remember pyraminx and clock that will be easy and that's it. Its going to take me anywhere from 9-14 hours depending on how much improve by 2014 at blindsolving hopefully a lot more. If i try this is there anyone willing to try this too other then mike because i know he wants to try this but doesn't have the time. This is my overall cubing goal, Once i try this i want to move onto a minx relay maybe ;)

This is the greatest thing ever. A lot of work though. I enjoy MultiBLD too much to bother with anything like that because time =P

If you're gonna do such a huge relay YOU MUST learn to solve with comms. With enough experience that relay should only take you around 3 hours. Are you still using U2/R2? Seriously. It will cut your solving time down dramatically. Plus it's awesome. I'll give you a breakdown of BH for corners and edges at the next meetup if you like.

Funny, I was thinking earlier today if I could be bothered doing 4BLD one handed. Has anyone ever tried blindsolving with feet?

But yeah Bryson, comms would be a good idea. Centre comms are easy and they'll save you a bucketload of time for the bigcubes.

hey...
i ve learned blindfold solving using pochmann method
in the part of memorising i ve some trouble
thats why i write the letters of memorisation on a paper and solve the cube by watching the paper..
am i going on the right way...or not..?
HELP...
