Random Blindfold Cubing Discussion

[mark49152]

i just thought about a new bld method first you solve the corners like a 2x2 using full eg then you use m2 to solve the edges anyone know full eg and want to help me make this a thing?

Are you proposing to develop EG algs that do not affect the edges? Or track how regular EG algs move the edges? What about parity?

 

[apollo]

i would track how regular eg algs move the edges but i haven't looked into parity. originally this was a regular 3x3 method but i thought it could be an efficient bld method if you can 1 look on 2x2

I don't know EG so can't comment on the move efficiency compared to 3style for corners, however, you also have to consider the memo time. You would need to figure out your EG solution, then figure out your edge memo accounting for how your corner solution moves the edges. That would probably be difficult and very slow.

 

[apollo]

yeah i guess so

 

[apollo]

i suppose it would be smarter and faster to develop EG algs that don't affect the edges and it would be easier to learn

 

[lucarubik]

parity wouldnt be a huge deal, pretty much as any other method, but im not sure how fast would those algs be, also is 1 look 2x2 possible 100% of the times? couse eg are two steps right?

 

[apollo]

yes 1 look 2x2 is definitely possible but when i tried to solve 3x3 corners like a 2x2 all of the edges hinder my recognition but that probably wouldn't be a problem with other people and yes eg means you get one side then finish it off

 

[apollo]

and to get the side there are easy ways to get one side without messing up the edges using basic commutators

 

[mark49152]

Even with a fixed orientation?

 

[apollo]

yeah you could just use set up moves

 

[apollo]

or you could just use old pochmann lol

I've counted the amount of corner cycles im forced to use L or R on, if i want to use a specific alg disregarding if its right or left turn friendly, i dont know the right amount (there are a bunch that can be done with L or R turns and its pretty much the same) but there are 8 more (and their inverses) right turn forced than left turn, this might be due to my particular style, or not, anyway i think it's interesting, i use UBL buffer btw
i wonder if this means that DBL would be the most U R F turns friendly buffer
i wonder if this applies to edges too, even tho 2 gen RU and MU algs rule and in order to use them the buffer must be in the U layer
*ive found a case i do it right handed just cuz im right handed, while left turns would be objectively better, there might be more mistakes but i dont think theerr are enough to tilt it to the other side

Think I'm starting to stabilize into sub-5 territory :O

Every few solves I'll get an 8.xx or so, but those are definitrly outliers. Earlier today I had an almost 9min solve where I couldn't for the life of me figure out where my memo was wrong (had 8 corner targets and 11 edges, wtf). Lost the scramble but anyhow, definitely not an usual solve.

Just a week ago I'd be stoked to get anything under 5min, and nowadays it seems to be very frequent (whether DNF or succesful).

About conjugate/commutator notation:

I know it's a very little/lazy thing, but how about having [A: B, C] be defined as [A: [B, C]]?

It's very rare that you'd need to write anything in the form [[A: B], C], but conjugates of the form [A: [B, C]] occur all the time. This is easier to type, and a bit easier to read (for me, at least).

I know some people do this out of laziness anyway, but it could be nice for it to become standard. Nothing would need to change about the notation for [[A: B], C] - it would only get rid of ambiguity if it becomes common notation.

Can someone explain to me to what extent edge comms are applicable to wings for BigBLD? Since I've noticed that comms like [U R U', M'] (I hope I wrote that correctly) work for 4BLD both using the left and right inner slice, while [R S R', U] does not work if you replace the S with an inner slice. Is there a way to know what comms work and which don't? Also, do people transfer a lot of their edges comms to BigBLD or do they learn new ones that are more suited for BigBLD?

Any pure comm that works like [Affect one piece in a layer, turn that layer] will work on bigBLD.
[R S R', U] brings the edge and the center into the U layer. It's fine on 3bld because it spins the center, which doesn't matter. On 4bld it spins a center bar and ruins everything.

Take [R' F R, S'] ([R' F R, f'] on 4bld)

When you do the R' F R you'll see that on the interchange layer (f) only one piece has changed so it's fine.

Edit: I don't know about people in general, but most of the edge comms that can be transferred to bigBLD, I use for bigBLD.

Question for anyone that can do 15+ cubes memoed sub hour in MBLD.
At the stage that I'm at, I roughly take 5-6minutes per cube in both memo and exocution. I'm the 4/5 or 5/6 type guy. I was wondering if you guys could tell me what the most beneficial thing you guys did to improve from like a 5 or 6 cube MBLD to 15+
Improve 3BLD?
Really long attempts?
Would love an answer

slice plane algs like [M', U2] on 3x3 cannot be transferred to big cube wings (that alg does work on midges tho on solved centers)

also algs with a wide insertion do not work for both wings and midges. example: [u R u', M2] on a 3x3. You would have to use [M:[U' R' U, M2]] or [r':[U' R' U, r2]]

and obviously setups to the 2gen U perm on 3x3 don't work lol

other than those types, everything else should be transferrable. but just because a comm works doesn't mean you should use it. i use S moves a lot on a 3x3, but f or S setups suck on midges and wings. also almost all of my 3x3 edge comms are regripless, but regrips are ok big cubes

For getting from 7 to around 13 in an hour, I was basically just doing one attempt each weekend (and 4BLD once a weekish too). After doing the same number of cubes for a few weeks, I would have improved my time enough to fit an extra cube or two in. My accuracy was pretty bad though, as in I would usually get 6/11 or something. But my times kept improving.

To go from 13 to 20, I started doing ~20-25 cube attempts in between my regular attempts. These would go way over the hour, usually 1:30-1:50. My accuracy was still pretty bad, probably around 60%. It's only recently that my accuracy has been getting better.

I think going over the hour by trying too many cubes is helpful, because next time you try a regular amount of cubes, it feels much easier.

Practicing memory sports. And for the execution - well, yeah, just 3bld
