My 4x4x4 Blindfolded Solve

Oho!

I've been waiting for this one Lucas! Great work!

EDIT: Definitely fake, it looks sped up [size=-4]XD[/size]

Wow - impressive! Your first one, and you're more than 4 minutes faster than my fastest time. (My best was last night - 27:05.94. My first one was 88 minutes, so at least I've improved a lot.) And about 10:30 memorization is 3 minutes faster than my best memorization time.

But, then, you're Lucas Garron, so it's really not fair. (Kind of like Harris Chan having his second ever successful 3x3x3 BLD in about 4 minutes - just not fair.)

I may have been guessing wrong from watching, but it looks to me like you were done with memorizing the edges in about 5 minutes! That's 4 minutes faster than me. So I'll ask you my question from the other thread - how do you figure out when you're done memorizing edges, and how do you figure out what ones you're missing if you're not done? Obviously, you're better than me at that.

yeah, totally sped up ;D

Ahh great you got this on tape. I would also try 4x4 BLD, if i just could do those damn centers

But I'm not Mátyás Kuti...
And I've done a gazillion [close] DNF's recently (2 a day for almost a week.)

For edges, I use M2 with M-slice edges using my own handling. I just memo cycles visually until I have all 24 accounted for (today I did one where I had an 18-cycle and a 6-cycle and spent 2 minutes trying to find two more edges - even I forget how to count and add, sometimes). I use a lot of relative successive memo: "this piece, then that piece on the edge next to it that the previous piece would end up in." I've gotten fast from 3x3x practice.

The single greatest jump in my 3x3x3 memo times was actually when I first tried 4x4x4 BLD (a long while ago: it was off by only 3 cycles...). After keeping track of that much info, 3x3x3 started becoming easier.

Centers are both annoying and fun. I think I understand all possible basic commutators, but I sometimes don't use the best one. I almost exclusively start with Ufr and 3-cycle one piece into it, another out of it. Much better than my piece-by-piece idea...

The great thing about visual is that you get a feel of how the cycles look. Unfortunately, memo methods that indiscriminately assign mnemonics are probably faster...

I've been waiting for this one Lucas! Great work!

You're both wrong. I invented a BLD time warp. So I took 23 minutes of my time to solve it, but spent less than ten video-minutes on the attempt.



Anybody got a good alg for the r2 parity?

Thats interesting, I might try a edges + corners 4x4 BLD (I can't do centres), and then see if I can improve my 3x3 times!

EDIT:
Cant you just do : [D U2 r' D' r, parity_alg]? It seems less moves than your parity + centres fix.

Hey Lucas try my parity fix: (r2, on the solver you already did this so forget about that) D' L' F ( l' U2 l' U2 F2 l' F2 r U2 r' U2 l2) F' L D
And congrats!

 

[KJiptner]

Hey Lucas, my approach for that Parity is this one:

Keep the slice, not the eges off (don't r2)
Shoot to the DF/FD cubie (whatever it is for you, I mean the one on in the l-slice)
like this for example: l2 U B' R U' B r2 B'UR'BU' l2
and you get a "pure"-Oll-Parity.

Hi Lucas,

I like this alg for the r2 parity courtesy of Daniel Beyer:

D R F' l' U2 l' U2 F2 l' F2 r U2 r' U2 l2 F R' D'

--edit--
Erik beat me to the punch on this alg, but I would probably execute with D R F' at the start
--edit--

Congrats on the 4x4 BLD solve as well!

Chris

 

[Erik]

Haha, I'd have to say I didn't totally got that by myself

 

[joey]

Wow Lucas, congrats from Chris Hardwick himself!

 

[Lucas Garron]

( l' U2 l' U2 F2 l' F2 r U2 r' U2 l2)

I think I'll use (l' U2 l' U2 M' U2 l' U2 l U2 r' U2 l2)
One more move, but only U, r, and l

This and the traditional parity alg come from domino, right (basically)?
Did anyone find them using ACube or so? How I could I search for a "pure" r2 parity alg?
