Random Cubing Discussion

[Yes We Can!]

Found this alg for an awkward shape OLL yesterday.
Setup: M F U R U' R' F' U' M'
Alg: M U (F R U R' U' F') M'

...not sure if it's new but I haven't seen people using it.

Is it just me, or are blockbuilding method users out in force recently? Every time somebody asks for help, there's a huge rush of blockbuilders running in to convert the newbies.

Yau/redux combination for 6x6x6:
- white and yellow centers
- make three full white edges, place on L as they are made
- finish the last 4 centers on M
- pair up outer and inner wing pairs, I don't think anyone uses this in practice but the recognition shouldn't be too bad
- finish entire rest of cube like Yau on 4x4x4

 

[uberCuber]

Making the centers of a 6x6 while preserving the three edge pairs just sounds annoying and is why I will always use pure reduction on cubes bigger than 4x4

It's not... you just do 5r moves instead of x moves. And you make sure not to turn F or B.

I seem to see that also. I gave up so whatevs.

I know how to do it, but it's annoying and slow to solve like that on large centers. (yes I realize that is an opinionated statement :3)

Even I don't do this. 6x6x6 sucks to turn when it isn't on qCube.

 

[irontwig]

So you solve all centres first? What about 5x5?

 

[Kirjava]

K4 on 5x5x5, anything bigger I do all centres first and then pair four edges.

I've recently been changing a lot of my OLLs, not to get better algs, but to get better orientations.
It occurred to me that the first thing I do when I see the OLL is look at the stickers on top (I then know which group it is) then I look at the stickers on the side to work out the exact one. It occured to me that if I had the same orientation for all the algs in a group (such as lighting ones always being on the left, or Knight Move ones always being horizontal with the corner pointing down), then as soon as I knew the group I could AUF to put it into the correct orientation, and while doing that I can work out which exact case it is. Which should save time (at least for someone who's as slow at recognition as I am).

 

[Rpotts]

there is on knight move that I always recognize from a U2 off, so sometimes I'll end up U4ing, such a nub.

Would this be a good way to solve big-cubes:

3 centres around one corner
Pair the 3 edges + 1 corner to make a N-1xN-1xN-1 block
Finish centres
Pair up one CE pair so that only R&U are left to solve
Solve petrus-style 2-Gen stage

Any Ideas?

I did this with PLL, all of the algs with adjacent corner swaps (2/3 of them) start with corners needing to be switched on R. That way as soon as I knew it was a PLL with an adjacent corner swap, I AUF'd and then recognized the edge permutation.

need to make a ECE pair to finish the 3x3x4
need to pair the rest of the edges and fix EO parity and fix CP for 2gen

Whoops, forgot to put that in. I was thinking more for cubes>=5x5, I think it would be quite slow on 4x4 relative to reduction/K4/whatever...

Actually Nevermind, just gave it a go, and its much slower than reduction.
