Ever had trouble/The best way to learn algs?

[Zeroknight]

For some odd reason, I just can't seem to nail the T-perm. I was working on it for like 30 minutes (dispersed, not all at once) and I know it by heart, but sometimes I do it wrong. I'm trying to get it into finger memory, but for some odd reason it won't work; and/or I haven't remembered it fully. Anyone else have this type of trouble with an alg?

Also:

How long does it usually take you to learn an alg? How do you do it?

Which J perm is better:

The one from cubefreak.net:
RU2'R'U'RU2'L'UR'U'L

or this on from old pochmann BLD:
L'URU'LU2'R'URU2R'

Thanks in advance.

TO LEARN AN ALG
(by me)

1. Practice
2. Practice more

4. Try it
5. Try it again

11. You're done!

Just repeat it over and over. Once you know it, do it slowly, and start going faster and faster.

And I use the first alg you put, but with a cube rotation somewhere in there. I think it is: R U2 R' U' R U2 Z U' R D' R' U I think. Not sure if it is Z or Z' though/

I think most people use the J-perm thats similar to T, what is it... Im blanking on it now. I personally like RU2R'U'RU2L'UR'U'L which is noticeably faster than my T-perm

I learned the Lofty F perm yesterday. It took me about 4 tries to get it without looking at the notations (around 8seconds per execution OH) and 20 tries to go full speed (around 4-5 seconds).
It took about 20 minutes to decide to actually decide if it is worth it to learn. It took less than 3 minutes to actually learn it.
First, visually memorize the movements, then execute it a few times to get the feeling.

I don't know why people can't just recite their algorithms. I can visually retrace all my algs in my head even after weird rotations. I can do mirrors usually too (except when there are many rotations in the alg itself) and I can also do that for inverses of my algs less than 10 moves.

I use R U2 R' U' R U2 L' U R' U' L
Best single 1.09, average 1.31
The other alg is R U R' F' R U R' U' R' F R2 U' R' U'
I do not like it.
I have single 1.11, average 1.35 for T perm.

One of the J perms can be done by doing the T perm with the last 4 moves first. I use that, and the mirror of the second alg posted for the other J perm.

 

[Zeroknight]

Thanks guys...Back to T-perm...

 

[Tortin]

Usually when I'm learning new algs I follow the F2L pair(s). And practise, of course.

I don't like either of those J Perms. I use R U R' F' R U R' U' R' F R2 U' R' U' It's very nice and fast, and it's very similar to the T perm.

 

[Tetris Cube]

The T perm has a lot of triggers in it, making it pretty easy to do fast if you know it by heart. I thought it was pretty hard to learn at first, but after doing it a lot, it became muscle memory.

Some algorithms you can remember visually or because others are very similar. The second J perm basically starts out as a Niklas, and everything from the U2 onwards is just R and U turns. I can sort of visualize that solution at that point, but I'd say it's more on the muscle memory side.

Edit: WTF I just found out on my own that the J perm I use is a Niklas + antisune with cancellations and U + U combined to make U2. Almost like how T/Y perm are two OLLs.

 

[Unknown.soul]

R U R' F' throws me off, I like the RUL alg (R U2 R' U' R U2 L' U R' U' L).

 

[Zeroknight]

fanwuq, please teach me how you know notation as well as the alg.

Also, which J is like the T?

 

[Ellis]

I guess it was this one, R U R' F' R U R' U' R' F R2 U' R' U'... I thought it was different than that, guess not. The last 4 moves of the T are placed on the front, everything else is the same.

I can just visualize all the movements of the alg in my head. Then I just type out the notation as I visualize the turns in my head. I do this kind of things a lot, especially for 444 FMC and partial speedBLD. I haven't tried a whole speedBLD yet, I'm just too lazy for that. I tend to just watch the cube for 20seconds per look and do it in 4 looks. Try practicing that.

Use http://alg.garron.us/
Type in the alg you want to learn and just watch it a few times. Then recall the alg yourself on your real cube. Do it a few times. Do an average of 100 and you should be able to do it faster than 6tps or your alg sucks or your fingers are even slower than mine or you aren't doing 2H 3x3...

I found a very very easy way to learn the T-perm:

I do [R U R' U'] [R' F] [R2 U' R'] U' [R U R' F']
All you have to do is think of it in chunks.
First [R U R' U'] -- easy: this is the sexy move
Then [R' F] -- turn the R' with your wrist and index finger the F
[R2 U' R'] -- your already in a funky position that alerts you of an R2 then follow through with your thumb and wrist the R'
U' -- remember to do this
[R U R' F'] -- do 3/4 of the sexy move and look at the cube and you'll see that all you have is an F' to finish with (do this with your thumb)

While your learning always do the alg in those chunks. If you forget a chunk (I thought that the [R2 U' R'] one was particularly hard), simply look at the alg written down again until you can do it from memory.

(That site is a great way to learn PLLs)

I reached 21 PLLs very fast in the past somewhat like that, because I was lazy to memorize new algs back then.

I learned that the 2 following OLLs:
- F (R U' R' U') (R U R') F'
- (R U R' U') (R' F R F')
were inverses, and when done one after the other, was either the Y-perm (1st then 2nd), or the T-perm (2nd then 1st, with cancellations).

Then I read somewhere that one J-perm could be done by placing the last 4 moves (R U R' F') of the T-perm on the start, then proceeding with the rest of the T-perm.

And I also read that you could do an N-perm by (R U R' U)J-perm(U' R U' R').
And I also read about the possibility of mirroring algs to the left hand.

IIRC, within a whole day of practice, I was able to learn and could somewhat comfortably use T, Y, J1, J2, N1, N2, as well the those two OLLs ("boxfish" and T with 2*1x1x2 blocks).

Although I've now replaced most of those algs, if you want to get the T-perm down, as well as many other perms, I suggest learning it that way as well.

 

[Musturd]

Musturd, your last move is F', not F (it's correct in your comment, bad wrong when you spell the alg - twice). Thanks for correcting.

Oops, thanks for pointing out

Thanks, that's awesome, except you had to replace them

Sorry, don't call me n00b, but what excatly is the sexy move? is it 1,2,3,4? RUR'U'? *runs*

I only replaced the left-hand mirrored ones because I felt I could go faster with RU algs (although I could already do an occasional sub-2 on the left-hand J-perm). I still use the same Y, T, N1, and J1. (although I'm looking for a shorter N1 right now...)

 

[Cloud_9ine]

Well my alg step by step process is:

1. Repeat the alg verbally with my phonetic system.
2. Start solving to my voice.
3. Start solving w/o voice and start to commit to muscle memory.
4. Once fully learned, start playing to a metronome to speed up.
