The "Request an Alg" Thread

[Lid]

On Sq-1 you can setup a star shape, turn the star one corner & then undo the setup moves, then solve it again.
Or you can learn one of the shorter parity algs (9 twists is the shortest).

edit:

What is the shorter alg? I can't find one that is less than 12/13 and I don't know what the star shape is....

Example how to use Star-shape to remove parity: /3,3/1,0/-2,-2/2,0/2,2/-1,0/-3,-3/ :: to restore corners after this: 0,2/-2,-2/(-1,0) (this is actually the ccw Operm (10 twists)).

Parity EPs with 9 twists: Z/op, H/op, O/H.

Shortest way to remove parity & keep "orientation" (7 twists): /-3,-3/0,-1/2,-4/4,-2/1,0/-3,-3/ (one of many ways to do this).

E: is there a good alg for this case?

There's a 2x2 block on UFL.

Thanks! I didn't think there would be many good ZBLLs on there yet because ZBLL was only recently added and it's a large set.

I uploaded most of my T set, so IMO the algs I post there are the best ones.

 

[unsolved]

but I can't find a good parity alg that will swap ONLY these two pieces and leave everything else I've solved good: View attachment 4717 All the algs I've found do bad stuff like unorient some corners and move other pieces around. I suppose that's because the alg I would need is very long, but I'd like to at least try it out to see if it's worth it.

Need an alg for this

 

[mycube]

I need an algorithm for BLD, Adrian showed it to me some time ago, but he can't find it anymore. It's for the parity in 3BLD with the targets UBL - UBR, UB - DF
normally I do a y L2 T-Perm, but I wanted to try it without cuberotation. Does anyone have a fingertrickfriendly alg for this?

 

[guysensei1]

If anyone can get a good fingertrickable alg for the pure 4 edge flip+ E perm 1LLL I will be insanely happy.

Bonus: get good algs for all of the E perm + 2 edge flip 1LLL cases and I will (not) serenade you.

Random 2alg1look case I remember from Kirjava's LL method. Not the best alg or anything but whatever.

Hey cmowla, do you still take requests for solving positions in a single commutator?

Absolutely. I can quickly do 3x3x3 solves, but anything larger than the 4x4x4 is impractical for me to do at the moment.

In addition, how do you want the commutator to look? Assuming you want 3x3x3 solves, do you want X to correctly orient all corners and midges? Or do you want the cube to look completely scrambled after X? It's customizable now.

Midges? Orient? Eh?

anyway I was just looking for a single commutator to solve G perms. Any G perm will do as I can easily invert and mirror them to get the rest

 

[QPowerPrime]

I use ZZ but instead of pairing corners and edges together i don't care which edges I pair with the corners, and permute them at the same time as doing PL4E after COLL. I made (almost) all the algs myself using commutators but I can't make an alg for a 4 edge cycle on E layer and adjacent edge swap on U. It doesn't matter which way they are cycled as I can just use the inverse.

This method is better as the recognition is basically just like PLL and I got a 4.77 single with double edge 3 cycle (U perm on U layer and a 3 cycle on E. Both were anticlockwise)


I also need a void cube PL4E parity algorithm that flips 2 edges

I just found several, but this is the best I have so far. (Cube Explorer didn't help at all with move count, and thus these are the actual moves I found by hand.)
[F' R' F U2 F' R F, R' U' R L' D L F' D R F]

Maybe optimize it to [F' l' U B2 U' l F, R' U' R L' D L F' z L u L y' z'] or [F' l' U B2 U' l F, R' U' M x D r U' F l F]?

EDIT:
Here's a longer (the above algorithm is fairly brief as a single commutator for this case) Y which is probably better for execution:
[F' l' U B2 U' l F, L' R' U' R U D r F2 U F' U2 R U x']

[Hssandwich]

Does anyone know a site that has a list for optimum OLLs?

 

[Artic]

This F2L case continues to annoy me. I try to avoid it and insert other pairs before this one, but I can't keep avoiding it. For the picture below but rotated y' so that the case is in the back right slot, how do you guys insert it? Any rotationless algs?
