Random Cubing Discussion

[jonlin]

I actually practice my solves while watching TV or a movie. When I do a timed solve it is stressing because I HAVE to get this and that done (cross, F2L) in a certain amount of time. Without that stressor I actually believe I solve the cube faster because I am relaxed enough to actually take in the things that I see instead of looking frantically.

So for a while I've been using my own big cube method. Maybe it has already been proposed or maybe it isn't that good (I prefer it to reduction). It isn't quite as complicated as K4 which is just weird to me.

For an nxn cube:
1. Centers
2. Pair up and solve cross color edges
3. F(n-1)L - 1: Solve all but LL and 1 CE slot. So pair up edges and corner for each slot
4. Strange parityish step - pair up last f2l edge (not corner, just edge parts), pair up 1 LL edge, orient all edges (and small-sub-edges) (petrus style), place last CE pair
5. COLL
6. ELL (3 algs per solve or less, usually 2, all but one alg (i guess two with mirrors) are comms)

sounds interesting, would you mind writing up an example solve?

The solve is like 200 moves which is way too much. However, I'm not that good at 4x4 (or big cubes, I'm just starting to practice them) so the centers could probably be cut down a lot as well as many of the moves in each step as most of the method is highly intuitive.

Lol and wow indeed. I didn't look farther than the titles so I missed this gem. Did you actually read the page or did that just catch your eye?

Each of these person's first official sub 10 solve was a sub 8. The last guy was averaging 17 seconds when he got his 7 second solve. I was almost certain it was a typo until I saw his his wca profile picture

It just caught my eye. I didn't even open up all the sites

Old cubers never die. Turns out one of the astronomy professors (Guy Worthey) here (Washington State University) used to solve in 30 seconds back in the day (say 30 years ago) he said. I handed him my painted guhong to give him an idea what the new cubes feel like and since it was already scrambled he promptly solves it. I was amazed.

He did three layers, one at a time, and then did something on the last layer that looked like it was solving the corners completely, then the edges. I showed him what I've learned of Fridrich so far, cross, F2L, and my not yet completely memorized 2L OLL and then 2L PLL.

Cause i know the good cubers watch this thread:
Pros and Cons of CLL/ELL Vs OLL/PLL.

 

[Rpotts]

OLL/PLL has relatively simple recognition and numerous excellent algs found and perfected for every case.

CLL/ELL has slightly lower movecount and a few less algs but the recognition seems to be more difficult, I'm not sure how good people are but recognizing ELL from 2 sides seems difficult.

you don't really need 2 sides, since there's fillped edges you can see stuff on U

 

[Escher]

That's a point actually, I imagine that ELL can be recognised with 2+ U face stickers & 3 F face...

Good point aronub.

Any other non-EPLL exceptions?
