The "Request an Alg" Thread

[Artic]

For the f2l case below:

Looking for an algorithm that inserts the pair into its slot but makes use of the adjacent empty slot. Preferably rotationless algs but all are welcome.

thanks for the help.

I don't have a good alg but I want to point out that 8 moves HTM is optimal regardless of the slot on the left (empty or not).

Just can't figure it out how to solve this final one. I didn't even know need to use what key words to find the solution on the Internet. Please help me and give me a solution for this. Thank you for the helping.
P.S. For the solution I'll put the orange as the front. (Facing me)

Has the cube ever been disassembled? Because I don't think that's a possible position.
E: nvm I forgot parity

No, it's definitely solvable. You just didn't finish edge pairing before moving onto the 3x3 stage. Pair the final two edges the way you usually would (one will appear unsolved, but that's because you have parity), solve parity, and then solve it like a 3x3.

This will do it, it's the shortest i can come up with:
2R2 R B' 2R2
2Rw U2 2Rw U2 2R' U2 2R U2 2L' U2 2L F2 2R' F2 2Rw' U2 2Rw'
2R2 B R' 2R2

Hi guys,

This thread is meant for people who are trying to choose between algorithms for any case. Just post the case and wait for somebody to tell you the best algorithm for it.

Me first:
Which algorithm to use for this ZBLL case:

1. L U' L' U2 L R U R' U R U2 R' L'
2. (U') R U R' U R U2 R' U2 R' U' R U' R' U2 R

I use the second purely because I'm most comfortable in 2-gen. I don't know how many people use the first, but I know lots of people like left sune then right sune or right sune then left sune for this case. Your first shift looks like a cyclic shift of that to save a move, but at the cost of an awkward L move at the end.

 

[pinser]

I think it really comes down to personal preference.
One person might be able to execute the first one really fast because of his/her turning style, while the other one is really slow for him/her.

Ask yourself: Which one do YOU think you can execute faster?
Time it a few times to see if it is fast (I'm no expert but I think sub-1.5 for every ZBLL?)

What about this one?

1. (U') R U R' U R U' R2 U' R' U' R U R' U' R2 U2 R
2. R' U R U2 R' U' R U' R U R' U' R' U' R U R U' R'
3. [U'] R U' R' U' R U2 R' U2 R U2 R' U2 R U R' U R U' R'

2. R' U R U2 R' U' R U' R U R' U' R' U' R U R U' R'
3. [U'] R U' R' U' R U2 R' U2 R U2 R' U2 R U R' U R U' R'

(U) R2 U R2 U R U' R' U R2 U2 R' U R' U R U' R'
Just the inverse of the alg that I use for the U case.
Not a bad alg either, a little awkward though.

I use the inverse of the third. Not because it's good, but because I stumbled on it while trying something with another alg and haven't bothered learning anything better.

 

[FJT97]

We already have such a thread. The request an alg thread. This is kinda doubled...

But what would you recommend?

 

[Hammer]

Which alg is best for this ZBLL? There are so many good ones.

Edit:
Nvm i found one!

Using a 7x7x7. I am aware that the technical term is not parity, please do not nag on that. The sides of the center keep switching when I use the (Rr)2 B2 U2 (Ll) U2 (Rr)' U2 (Rr) U2 F2 (Rr) F2 (Ll)' B2 (Rr)2 algorithim. Thank you!

You can just use a center rotating algorithm, like M E M' U M E' M' U' to rotate the U and R centers 90 degrees each, or two T-perms to rotate the U center 180 degrees.

Thanks, but it is not rotating, the two rows of the center on either side of the middle line are swapping places.

 

[SpikeCuber]

Just curious, are there any algorithms for 4x4 that do nothing but turn the entire cube around, without and cube rotations? also, no,"l'r" does not count, and neither does "L' R 2L' 2R". I mean an algorirhm that methodically swaps everything around
