[Video] COLL U1 + U2

[Pyjam]

Hi there,

This is my first video. I'm studying the COLLs. Some are really not easy to execute, so I search new ways to execute popular algorithms. Here are two I discovered yesterday. I don't know if they're already known and efficient. At least, I'm satisfied whit them. Hope you'll like them.

COLL U1 : (x') M' U' (R2 U2' (r' F r) U2 R2) (r' F2 R)
COLL U2 : (x) (R' B2' R) (U' R' U) B2' (U' R U)

 

[Cool Frog]

First one.
(R U2 R' U' R U' R2 U2 R U R' U R)

 

[Pyjam]

First one.
(R U2 R' U' R U' R2 U2 R U R' U R)

This is T1, not U1, I believe.

Oh wow, just don't listen to me. I'm dumb. Sorry for polluting your thread with stupidity xP

Cool Frog is correct, your first case can be solved with the alg he posted, and most people prefer that.

Nope, they're different cases.
Cool Frog's is for a non-moving T and Pyjam's is a U that swaps the "headlights".

R' (Y perm) R and F (Y perm) F' are nice algs for the first case.

 

[ErikJ]

for the first one: R' U R U' x' U L' U L U2 R U' R' U x

I don't use COLL if I get the second case because the only algs I know for it aren't that great.

Thank you, young lady!

For your COLL U2 l use this alg U R U R2 U' R' F R U R2 U' R' F'

 

[ErikJ]

For your COLL U2 l use this alg U R U R2 U' R' F R U R2 U' R' F'

wow, that's an awesome alg. I might as well share the really nice OH alg I use for it. btw, I use my right hand so it's kinda L heavy. L' U2 L U2 R U2 L' U2 L U2 R'

 

[Athefre]

I still prefer FR2U'L'UR2U'LUF'.

 

[amostay2004]

For your COLL U2 l use this alg U R U R2 U' R' F R U R2 U' R' F'

Interesting, never thought of using that commutator.

Anyway I use R' F2 R U2 R U2 R' F2 R U2 R'. My best is 1.18 with it

 

[Pyjam]

For your COLL U2 l use this alg U R U R2 U' R' F R U R2 U' R' F'

Sorry, I don't understand. It's exactly the kind of alg I want to avoid: long, hard to memorize, and impossible to execute. Not for me.

 

[DavidWoner]

for U2:

(r' L') D2 L U2 L' D2 L U2 r
or
x' U2 R2 U' r2' D R2 D' r2 U'

 

[ErikJ]

if anyone has a nice alg for the case and it's mirror I'd appreciate it: R' F U2 F' R F R' U2 R F'

 

[DavidWoner]

if anyone has a nice alg for the case and it's mirror I'd appreciate it: R' F U2 F' R F R' U2 R F'

r U R' U' L' U R U' l U R' U R U2 R' and inverse/mirror. Whichever you prefer.

 

[ryo]

For your COLL U2 l use this alg U R U R2 U' R' F R U R2 U' R' F'

I use this one too, it's my favorite (sub 1.5 seconds) but for this case I also know :
F R U' R' U R U R' U R U' R' F'
and
x' R2 D2 R' U2 R D2 R' U2 l

 

[Athefre]

if anyone has a nice alg for the case and it's mirror I'd appreciate it: R' F U2 F' R F R' U2 R F'

I use L'U2RU'R'U2LU'L'URU'M' and it's inverse for COLL.

Hey guys just found a very fast alg for the COLL U1 case R U' R2 U' R2 U R' F' R U R2 U' R' F R2 hope you enjoy it as much as l do

Looks awful read on the post. Looks wonderful executed on the cube Adopted !

That's the same ZBLL as R' (Y perm) R
