3-cycle Freestyle Commutators and Algorithms for BLD Edges

三循环法盲拧换棱公式

Lucas Garron; March 2, 2008

Below are all the useful algs I know that can be used for freestyle BLD edges. You cycle stickers by setting up into one of these. I don't want to discourage anyone, but you should only try freestyle if you know what you are doing, in which case you shouldn't need an explanation of how to use these: think of this as a collecetion of algs, and hunt through them to find something you micht not have thought of.


Notes:
[*]I use UF as my buffer, but I've consider UR, UL, and maybe DF (to go with M2), possibly even UB (free buffer on U is also not unlikely).[*]{U} represents either U, U2, or U'. I'm using this notation to represent a class of commutators.[*]A lot of these either work or have variations (try doubling an alg, with cancellations) that work on big cube wings and midges.[*]Although I haven't made it obvious, note that all of these are at worst convoluted conjugates of commutators.

R2 U R U R' U' R' U' R' U R' (UF UL UR)
L2 U' L' U' L U L U L U' L (UF UR UL)

... 2-gen U-Perm/Allan. I suggest you try to get used to all 8 inverses and mirrors on U.R2 U R U R2' U' R' U' R' U2 R' (UF UB UR)
L2 U' L' U' L2 U L U L U2' L (UF UB UL)
R2 U' R' U' R2 U R U R U2' R (UF UR UB)
... This variant differs in exactly 2 twists. It's also good to know it from different angles. I don't use the inverse (R' U2 R' U' R' U' R2 U R U R2), but you might like it better.U R U R' U' R' U' R' U R (DR UF UL)
R' U' R U R U R U' R' U'(UL UF DR)
... Another variant. Good to know the 8 mirrors/inverses/angles each.U R U R2' U' R' U' R' U2 R (DR UF UB)
... Combination of two variants. Good to know, but less useful.R2 U R U R U' R' U' R' U' R' (UF FR UR)
R U R U R U R' U' R' U' R2 (UF UR FR)
... Yet another way to avoid setups. U x U' M2' ULU' M2' Ur'U' (UF LU FR)
U r U' M2' U L' U' M2' F x' U' (UF FR LU) Whenever the previous is inapplicable around a corner. M' U2 M U2 (DF UF UB)
U2 M' U2 M (UB UF DF)
R U2' M' U2 R' M(UB UF DF)
u2 M' u2 M' (UF DF DB)
... Whenever the previous is inapplicable around a corner. F2 U' M' U2 M U' F2 (UF UR UL)
F2 U M' U2 M U F2 (UF UL UR) Petrus Allan / Conjugate. M2 U' M U2' M' U' M2' (UF UL UR)
M2 U M U2' M' U M2' (UF UR UL)
M2 U' M' U2' M U' M2' (UB UR UL)
... MU-version. R U R U R U' R' U' R' U' (UF UR BR)
... Pure form of the 2-gen Allan. Can be written as .M U M' U2 M U M' (UL UR FU)
M' U' M U2 M' U' M (UL UR BU)
M U' M' U2 M U' M' (UR UL FU)
M' U M U2 M' U M (UR UL BU)
... Deals with non-Allans on U. (UF DF D_)
(DB UB U_)
(DF UF U_)
... I think Hardwick calls this "tossing".[{M'}, U' {R} U]

... There are insanely many variations on this, and I'm not even going to try listing them. M and R can be any amount, you can use the L face, too, RU'R'U/etc. work for setups, any inverses & rotations/angles & mirrors of these work... but these all basically involve exchanges on a middle and outer layer.

Allan variant
Has a nice rhythm to it; also found this one myself.
Make sure to perform it on two unrestricted faces (like U and F)(R2 U R U R) U' (R' U' R' U' R')
Here, with the F face being used as R.

GOOGLE太可怕了

3周期自由式换向器和算法隐血边

2楼发的太深奥了,呵呵

回复 2# 的帖子

回帖发这种起不到任何帮助的自动翻译文字还不如不发~~

有道理,我直接看就看懂了

刚看了一下。
R U2' M' U2 R' (UB UF DF)这条是错误的。

F2 U' M' U2 M U' F2 (UF UR UL)
F2 U M' U2 M U F2 (UF UL UR)  Petrus Allan / Conjugate.  
M2 U' M U2' M' U' M2' (UF UL UR)
M2 U M U2' M' U M2' (UF UR UL)
M2 U' M' U2' M U' M2' (UB UR UL)
这些公式不顺手不如原来的。

U x U' M2' ULU' M2' Ur'U' (UF LU FR)
U r U' M2' U L' U' M2' F x' U' (UF FR LU)
这两条不是最短的最顺手的。大家不要用。
