[Help Thread] F2L Discussion and Help

[Xxcookid123xX]

Well, I still don't get what you mean but if it's the F2L that's making things difficult, try this tutorial and part 2 as well as other videos on the channel and others.

Alright so, thanks to that tutorial I finally get how F2L works. So now I see how F2L can be done fast, but I'm still high on end about all those algs. I can use these websites for reference*, but the thought of knowing all of them seems impossible.

But can someone explain this?

I don't get how you flip this corner.

Ignoring the cross
R2 D'
Or turn the green face 180 degrees then turn the white face anti clockwise.

Assuming your cross is complete, L U L' will pair the edge with the corner, and then R U2 R' will put then both in place. The reason it looks like the corner is flipped is because the white and yellow stickers don't match.

Regarding the remembering and revealing algorithms thing. It's a lot easier than you think. Think of all the things you already remember. How many people do you know? How do you see a person's face and you immediately know their name? And how many objects can you name? I don't understand how memory works, but it's amazing. Adding just a few dozen OLL and PLL cases to that massive list is tiny. In terms of remembering the moves, it all goes into muscle memory. It's like a musician who goes up on stage and plays a piece on an instrument. The music is remained in their muscle memory from hours of practice. Learning algorithms is like that, just much much easier since algorithms are much shorter than your average piece of music.

I think you need to step back from tutorials for a while and try working with the cube on your own. Think about how the pieces move, and try to see if you can figure out your own way of doing steps.

I did get the twisted corner fixed with a more complicated way, i'll check out your way later. (It's 3am here lmao) But I have one question about PLL, is it quicker to do 2look PLL or my way of getting headlights in beginner's method [x R' U R' D2 R U' R' D2 R2], then finish with this algorithm [put solved side in back, if there's no solved side do algorithm to get solved side. R U' R U R U R U' R' U' R2, usually have to do twice, very quick algorithm to do]?

With some practice, recognising the correct PLL is definitely quicker than doing an alg.

What do you mean? All the PLL cases need an algorithm to solve.

Yes doing 2look pll is better than doing incomplete 2look pll.

 

[1973486]

Right now you're doing:

• A perm
• U perm
• U perm

And it will be quicker to do

• A perm
• Recognise U perm
• Execute U perm

 

[Silverback]

But I have one question about PLL, is it quicker to do 2look PLL or my way

Your way is essentially 2look PLL. Your first algorithm is an A-perm and you use it to permute the corners. It only works, if you have an adjacent swap. You recognize that by seeing only one pair of headlights.
If you don't have headlights, you just do the A-perm which gives you headlights. You will want to learn any PLL that swaps diagonal corners (E, N, V or Y) pretty soon.
As soon as the corners are permuted, you are left with one of four cases (Ua, Ub, Z or H). Right now you use one of the U-perms to solve all these cases. You probably want to learn the other three next.
So you are just four algs away from 2look PLL. As soon as you got these down, you can solve PLL with a combination of two of these algs.
Then you already know 6 of the 21 PLLs.

Alright so, thanks to that tutorial I finally get how F2L works. So now I see how F2L can be done fast, but I'm still high on end about all those algs. I can use these websites for reference*, but the thought of knowing all of them seems impossible.

I have been cubing since Christmas Eve 2015, and I started learning CFOP around March 2016. I finished learning all of the algorithms a few days ago. Yes it might take a while, but It is far better in the long run. My friend from school has been using the beginner's method for 6 years, and he averages 26 seconds. After slightly less than one year of CFOP, I average 22 seconds, and get sub-20 solves about 15-20% of the time. Trust me, CFOP is well worth it.

come on man, http://lmgtfy.com/?q=f2l+algorithms

it's not that hard

I already have 2 sites for OLL and PLL algorithms. F2L only has 2 algorithms though.

F2L is mainly intuitive, but if you were to learn algorithmic f2l I believe it's something like 54 algs

No thanks.

 

[DGCubes]

No thanks.

The point of F2L is that it's supposed to be intuitive, and you're only supposed to learn algorithms for really hard cases. There are a ton of websites with F2L algs though; algdb.net is always a good source.

 

[pglewis]

If you're using the beginners' method that solves the first two layers by inserting corners first then you're already doing an inefficient F2L. Watch the pieces when you go to insert a second layer edge and you'll discover that you're removing the solved corner, pairing it with the edge, and then solving them as a pair.

The beginners' method is initially easier because solving all the corners first limits the F2L cases for solving the edges to just a couple. CFOP is faster because you're not solving every corner twice, once in the corner stage then unsolving and pairing with an edge.

One of Missouri's Top Rubix Kids Demonstrates PLL Algorithm [AMAZING]

Here's how it goes:
1) learn algorithms
2) learn when to use them
3) practice
4) get better at recognizing them from different angles
5) practice more
6) PLL master rubix kid

So I did beginner's corners then edges and F2L intuitive timed, and these were the results:

So yeh, obvious problem. Is there a trick to get faster? Are the algorithms faster?

This phenomenon is very common when trying a new method for the first time, and is nothing to worry about. It's called "not being very good at it yet". As an experiment, do 10,000 solves using intuitive F2L, and then repeat your measurements. You are likely to find that you have improved greatly at intuitive F2L - and you might even be faster than with beginner's method! This trick is called "practice" and is perhaps the best-kept secret to improving cubing skills.

That's not what I meant. I meant, I've done much practice. But it takes the same amount of time because finding the corners and edges takes too long.

If F2L makes you 5 times slower, you either haven't done enough practice or are doing something wrong.
