Random Cubing Discussion

[JonnyWhoopes]

This is a really ugly commutator for the standard 2gen U perm, is there a nicer one?
[R2 U R U D' z', R U' R']

[R2 D', U2 M' U2 M]

::EDIT Nvm, I'm horrible at comms. That's actually [R2 D': [U2, M']]

I just made a 2x2x1 scrambler for the lolz.

Download and change file extension to .swf

ohai there. I really should just stop posting.

Aron: oright, I was just thinking about corners and just assumed Ben's number was right.
Did you really learn it ALL by heart without understanding the logic behind it?

Well I had to make the alg first, that requires the commutator knowledge. But I used programs to associate letter pairs with the alg (like KR = RUM'U2MUR'), so that I wouldn't have to do any thinking while solving corners. Edges are still a bit thinky, I haven't fully associated all the cases yet, but I can solve every cycle.

im sorry, im entirely new here and thought that the "random cubing discussion" page would be the place to ask this. how do people get so fast at things like the megaminx and v cube 7? im already entirely too slow with them (megaminx is 8 minutes 5 seconds and the v7 is about 18 minutes). but then you go to youtube and like, within the first minute they have all the centers done. i know it requires practice, but surely it must require something more?

that something more is even more practice, and with practice you discover your own tricks to deal with certain cases faster. There really is nothing else to say. For megaminx I can sub-2:15, and I have never looked at a single megaminx tutorial of any kind, and I very rarely practice it, same with 7x7, and i can sub-9 that

well then compared to me i guess you are the ubercuber

Also, for future reference, questions that generally would have only one answer, or limited answers, should go to the OAQT (One Answer Question Thread).

Welcome to the forums!

0.o....

So what is the method with all of the 3 cycles and like, 600 algs then?

It's lolBH.

its the internet, so its hard to tell the tone of this post, but just to clarify I wasn't trying to show off that I am faster than you (there's no point in that; besides I am slow compared to a lot of people anyway). my point was that I have gotten to that speed without looking at tutorials; improvement came simply from practicing and finding out tricks myself

Lol, pretty useless, but i just figured out how to do the last layer with only F R U R' U' F' + setups.
Making T= F R U R' U' F'

OLL:
Pretty easy to orient edges..
To orient corners use this Antisune alg: T U' T U T T

PLL:
If the corners are diagonaly permuted use:
Y perm: T T U2 T U' (Antisune) U2 (Antisune) U' (Antisune) U

If the are adjcently permuted use:
F R' F' (Y perm) F R F'

To permute edges use:
U perm: T (Antisune) U T

41secs single =P:

The method i use is intuitive cross + second layer edges, then I use FRUR'U'F' to solve the first layer corners, then OLL and PLL.

If you ever run into a LL that is solved apart from two opposite flipped corners and you do not know commutators:

A right-left or left-right combo of the fingertricky "corner-twisted-in-place" F2L alg twists your opposite LL corners:
R U R' U2 R U' R' U R U R'

BTW I was amazed to find that a google search on speedsolving.com:"R U R' U2 R U' R' U R U R'" only resulted in two posts, not even mentioning it's use for F2L

I would just do R U' R' U R U2' R' U R U' R' for F2L and not pay attention to anything else.

R U R' U2 R U' R' U R U R'

So you're saying the full algorithm would be:
R U R' U2 R U' R' U R U R' y' R' U' R U2 R' U R U' R' U' R

This is actually pretty decent, although there are certainly a few ways to do those twisted-corner ones, so I have a feeling I'd end up getting this one wrong as often as right. Perhaps this is nicer:
(r' u R2 u' r U2)2
And a 2gen way based on the sune-sune 2-flip:
R U' (R U R' U R U2 R' U2 R' U' R U' R' U2 R) U' R'

My RUL alg for that case, which I think flows nicely.

R U' R' (L' U2 L U L' U L) R U2 R' U'

Welcome to CLS!

 

[Cubenovice]

Because I am very lazy when it comes to learning algs I execute this as:
R U R' U2 R U' R' U R U R' y L' U' L U2 L' U L U' L' U' L

That's right I am so lazy I just use left handed versions of most my algs... Also for OLL and PLL

I'm sick of my Dayan + MF8, it's like brand new and I freaking hate it!!! So, I'm thinking of selling it online, what would be a fair price for one? I have barely used it and it is pre-lubed.
