Square-1 BLD

[byu]

I've been really interested in making a Square-1 blindfolded method, and I've been thinking about it a lot recently. So, I've got this idea for steps.

Memo
1. Memo Cubeshape and track pieces through Cubeshape
2. Memo Cycles of edges starting with UB, each edge being lettered A-H, creating images in pairs.
3. Memo Cycles of corners starting with UBL, each corner being lettered A-H, creating images in pairs.

Of course, since there aren't many pieces, visual memorization is also a good idea.

Execution
1. Cubeshape
2. Bring edges up to UF and keep in cubeshape, use alg /(3,3)/(1,0)/(-2,-2)/(2,0)/(2,2)/(-1,0)/(-3,-3)/(-2,0)/(3,3)/(3,0)/(-1,-1)/(-3,0)/(1,1)/(-4,-3) to swap UB with UF.
3. Bring corners up to UBR, and use an alg to swap UBR with UBL, use alg /(-3,0)/(0,-1)/(2,0)/(0,4)/(2,-2)/(0,4)/(4,0)/(0,-4)/(0,2)/(0,-5)/(3,0)/ (Thanks Maarten for the alg)

4. Feel the Square-1. If it's not square yet, apply this alg. /(6,0)/(6,0)/(6,0)

Remember, this is just a general idea, I don't know how well this would work. Tracking shouldn't be too hard, because there are only 16 pieces to keep track of, although this would decrease success rate. However, anyone who's had experience with 3x3 Speed-BLD, even if they're not very good, should find this much easier than tracking 3x3 pieces, since there is no orientation to worry about, only permutation.

If anyone interested in helping me work on this method, I'd appreciate it. If you have any suggestions or comments that might make this better, please tell me. I really want to someday get a successful Square-1 BLD solve, and I think this method might work for me.

Again, this might be a terrible idea and I just have no idea about it, but I thought I'd announce it in case anyone was interested. If nobody posts, I'll assume nobody is interested and I'll work on devising the method myself.

#1= the whole reason people haven't been able to do Sq-1 BLD
EDIT: there was a thread on this, but I can't find it with the new search.

correct me if I'm wrong, but A-F is only 6 letters, no? and you have 8 edges and 8 corners

 

[byu]

Oh yeah, should be A-G, 7, since buffer doesn't count

 

[trying-to-speedcube...]

Your corner swapping alg: /(-3,0)/(0,-1)/(2,0)/(0,4)/(2,-2)/(0,4)/(4,0)/(0,-4)/(0,2)/(0,-5)/(3,0)/

Of course the first step is the hardest. A nice possibility though is to learn what the alg for the cubeshape does to the permutation of the pieces. This requires a lot of work to do though...

 

[DavidWoner]

I still think speedBLD is easier. The algs are a lot simpler, and once you're through CO can move only a few pieces at a time.

 

[byu]

Speed BLD would have faster execution, but memo would probably take quite a while.

Oh and Maarten, thanks for the alg. Once I'm comfortable with it blindfolded, I'm going to try a Square-1 Square BLD (e.g. Start from cubeshape) on the bus that will leave in 4 hours

 

[byu]

Sorry for the double post, but here's a sample lettering system, and I decided to go A-H just so every piece has a name, even the buffer.

Edges
A - UF
B - UL
C - UB
D - UR
E - BD
F - BL
G - BF
H - BR

Corners
A - UFL
B - ULB
C - UBR
D - URF
E - UBL
F - ULF
G - UFR
H - URB

Cube shape is the only problem, the rest is trivial and can be done many easy ways. I don't understand why you discuss the rest in detail but more or less ignore the cube shape issue. I suggest to first talk about and make up a reasonable method for safely and effortlessly tracking pieces to cube shape. Then again, I'm a Square-1 beginner and don't know shortest paths to cube shape from all shapes.. Maybe it's not hard anymore if you do?

anyone who's had experience with 3x3 Speed-BLD, even if they're not very good, should find this much easier than tracking 3x3 pieces, since there is no orientation to worry about, only permutation.

Well... for the 3x3x3, there are 24 possible positions for each edge (12*2) and for each corner (8*3). For the Square-1, there are also 24 possible positions for each piece (24*1).

Huh?

8 for each edge, 8 for each corner?

What's wrong?

 

[Stefan]

8 for each edge, 8 for each corner?

Nope. Every edge and every corner can start at one of 24 positions.

 

[DavidWoner]

8 for each edge, 8 for each corner?

Nope. Every edge and every corner can start at one of 24 positions.

Thats only if its not in cubeshape though, for the method byu is describing you don't memo positions until after you've traced pieces through cubeshape. If you are talking about 24 positions while both layers are square then I have no idea what you are talking about.

Sorry for the double post, but here's a sample lettering system, and I decided to go A-H just so every piece has a name, even the buffer.

Edges
A - UF
B - UL
C - UB
D - UR
E - BD
F - BL
G - BF
H - BR

Corners
A - UFL
B - ULB
C - UBR
D - URF
E - UBL
F - ULF
G - UFR
H - URB

I don't know about you, but on my square-1 there is no BF edge, and I only have 4 corners in the U layer.

 

[Stefan]

Yeah. Which is what byu and I were talking about. Step 1, getting to cube shape.

Ah yes, I see that now. I was still stuck on the earlier discussion of post-cubeshape memo.

How is Suare-1 ever going to be a blindfolding event if you can can feel if it's a cube shape or not? It's cheating .

I completely agree

Yeah, like that really helps.

For anyone who happens upon this thread and is reading it later, I wanted to add that I finished a way to do it (and I didn't want to spam the forum with a new post). So here is my method for solving it:

And as it turns out, feeling it to see what shape it is is actually part of the method. But I don't consider it cheating.

Darn. I just tried that and got it into cube shape... But then i realized that i had no idea where the pieces were... Wow. I'm dumb. That obviously doesn't work.

Oh wow guys... cmon

that's ludicrous. whoop de freaking do. you obviously don't understand how inane that point is.
