A System For Intermediates- CFECP & CFEOP

[dChan]

I was devising an easy way to learn Fridrich when I came up with this:

C-Cross
F-F2L(Keyhole Style)
E-LL Edge Orientation
C-LL Corner Orientation
P-Permutation of LL(Fridrich algs)

You have to know how to do keyhole and to orient LL Edges and Corners already. This way you learn the 21 algorithms and you'll get faster as you're learning. After you learn the LL Permutation algs, then you learn 7 LL Orientations and use them to orient the corners. Then learn to orient the corners first without doing the edges and learn the edge orientation algs. Then you will progressively learn all the orientation algs while still getting faster instead of slowing down so you can start to implement Fridrich algs. This way you learn a little at a time. So here is the outline of how you should learn:

1.
C-Cross
F-F2L(Keyhole Style)
E-LL Edge Orientation
C-LL Corner Orientation
P-Permutation of LL(Fridrich algs)

2.
C-Cross
F-F2L(Keyhole Style)
E-LL Edge Orientation
O-LL Corner Orientation(Fridrich algs)
P-Permutation of LL(Fridrich algs)

3.
C-Cross
F-F2L(Keyhole Style)
O-LL Corner Orientation(Fridrich algs)
E-LL Edge Orientation(Fridrich algs)
P-Permutation of LL(Fridrich algs)


4. Now you can learn the rest of the algorithms.


You can find algs on Joel's solvethecube.co.uk and learn to rotate corners and edges from his "Getting Faster" tutorial. Does this seem like a good learning system?

I think there should be some modifications to this method:

Step 1. I don't think you can expect someone to learn 21 permutation algs while he doesn't know the 7 corner orientation algs.

Step 2. Makes sense. I am assuming the LL Edge Orientation is 1 of 4 cases, "skip" (4 edges oriented), "small l" (9 and 12 o' clock oriented), "stripe" (9 and 3 o' clock oriented) and "nothing" (0 edges oriented

Step 3. Why would anyone do Corner Orientation and than do edge orientation. These algs are actually longer and more difficult compared to step 2. Seems to me that times with step 2 would be better compared to step 3.

But isn't this basically the way everyone moves from a beginner method to full Fridrich?
4 look Beginner: (EO=1, CO=1, CP=1, EP=1), 4 algs only, repeat some algs multiple times
4 look Intermediate: (EO=3, CO=7, CP=2, EP=4), 16 algs, never repeat an alg multiple times
3 look Advanced: (EO=3, CO=7, P=21), 31 algs, permutation is now 1 look
2 look Full Fridrich (O=57, P=21), 78 algs, orientation is now 1 look

lol, I was thinking of trying to memorize all the algs first instead of progressing slowly so I thought maybe other people did the same.And you can learn the permutation without the corner orientation algs. I do: x R2 D2 R U R' D2 R2 x' to orient/cycle the corners anti-clockwise and have another alg to do it clockwise.

Something is wrong with that. R2 needs to be replaced with RU'R, or you messed something else up. And that is just a basic corner cycle (no orientation).

AvGalen is right, you can't just force feed yourself algorithms. If you can't do basic orientations, you can't be expected to recognize and execute a permutation with any sort of speed.

Don't want to get nit picky, but I like to throw in a V or Y perm (or any diagonal corner switch) in the Intermediate to make it a full 4-look.

I also tried the algorithm and couldn't figure out what it was supposed to do. I am glad someone else also noticed the error.

Tenderchkn: I don't mind you being nit picky, but as I said: "4 look Intermediate: (EO=3, CO=7, CP=2, EP=4), 16 algs, never repeat an alg multiple times" has 2 algorithms for CP and also states that you never have to repeat an alg multiple times. 1 alg is for a corner 3-cycle (or as I perceive it, for the case where 1 face has the same color stickers for the ll-corners) and 1 alg is for a diagonal corner switch (or as I perceive it, for the case where no face has the same color stickers for the ll-corners)

And I know some beginners that learned all algorithms for F2L at once, but they were much slower than I was on the F2L (and I am not fast).
I also know an expert that doesn't even know all of OLL in 1 look yet, but he is twice as fast as me.

I think you need a basic set of algorithms that allows you to always solve the cube in a reasonable time. You should be able to execute all of those algorithms at full speed all the time, recognition should be almost instant and look-a-head should be possible. Then learn some extra algs that allow you to do 2 steps at once and use them at home when you practise, but not at competitions untill they have become as easy to do as your previous 2 step method.

Oops, i had an idiot freeze just now. It is hard to remember how to write down the algs off the top of my head.

But anyway, I wrote a wrong alg, lol. The alg is on Joel's website(solvethecube.co.uk) under the getting faster section. I only requires 2 algs(an alg and its reverse) to do the 7 OLL cases. So that would be easier to do then you slowly implement Fridrich OLLs.

Does that make more sense? I'm a little bugged out right now, lol. :blink:

 

[tenderchkn]

Yes, corners can always be oriented with at most two Sune's, but the point is that corner orientation is easier, both to recognize and to execute. To learn PLLs before you can orient in two looks is like learning to run before you can crawl. After you can solve the last layer with at most 4 algorithms each time, then you can move forward and learn 14 additional PLLs.

Now, there is no set order in which you should learn, it's just that as you get faster, you naturally become better at recognition. At the beginning, when your recognition skills are poor, it doesn't make sense to learn a G perm if you don't know how to recognize it, while you can recognize a corner orientation easily, but are spending too much time executing it.

Here is a beginners-tip for the corner OLL:

One of the fastest moves that exists is called the Sune. I perform it as R U R' U R U2 R'. If you look at the R-moves it is just R, R', R, R' and if you look at the U moves, it is just a full circle!

Now here is the tip (i am assuming yellow is the color of your last layer):
Count the number of corner pieces that have yellow on top;
If there is exactly 1, hold the cube so this piece is in the Up-Left-Front position,
othermwise, hold the cube so that the piece in the Up-Left-Front position, has yellow on the left

Perform the Sune and repeat the above step as many times as necessary untill all four yellows are on top. This should be 1,2 or 3 times, but never more.

If you want to do this a little more advanced, you should also learn the inverse Sune. It is exactly the same as the Sune, only the U layer makes a circle counter-clockwise: R U2 R' U' R U' R'. Now you can do what dChan does and you only need to perform 1 or 2 of those Sunes (but recognising the positions will be more difficult)

The next step would be to learn all 7 algorithms for Corner Orientation so you never have to use more than 1 algorithm for it.

I hope this was helpfull

Thanks AvGalen. When I get faster I'm definetly going to write something about how to get faster and your guy's tips are great.
