L2L4 - The Lost Methode ? Help Find it!

[nickvu2]

Quick update and request:
F D' L U' L' D F' R U2 R'
U' F2 U R U R' F2 U2 F U' F (except with a flipped FR)
I can't seem to find a good alg for these two. Ideas?
They are both CO cases, shooting the edge to FL.

(the 16) EP is done, and can be found in the post above this one.
40/118 CO are done
A few (~5 of each) CP and EO are documented.
This brings me to about 30% of the documentation.
I plan on finishing CO tonight, bringing me up to over 60% of documentation.

Damn dude, you're awesome! Keep it up!

Not much of an improvement, but these were the best I could find:
D' L U L' D F U' R U' R' F'

F L F L' U' R2 U R U' R2 F' (is this what you mean by flipped FR?)

Gah sorry, but those algs still aren't very good.
There are just a few cases that are quite troublesome. :/

 

[StachuK1992]

Update:
50% done.

62/118 CO
29/30 CP (I can't find anything good for one)
5/56 EO (haven't started yet, really)
16/16 EP

112/220 L2L4

I've been avoiding EO on purpose. I for some reason think that it's going to be nasty.

EO Iteration and solving FL edge

Idea is to do somthing like Roux EO instead of lerning all EO algs, but the system I tell you here, is not complete (does not handel all possible cases) an for some cases it much to bulky.

1. when to use: FR should not be solved , FL should not be solved, a minimum of 2 miss oriented edges in U , at least on oriented U layere edge in U

2. AUF: place oriented U layer edge at UF EDIT: if there are multiple oriented you may take an already solved one.

3. CONJUGATE: F'

4. M'UM / M'U'M / M'U2M like in Roux to orient all edges ( U-layer edges are oriented when facing up or down, the other edges are oriented when F-color is not facing up or down)
optimaly the final move places the FL edge to DF

5a. Do NOT deconjugate !!! because in most cases this would bring an Ulayer edge to FR , but this edge would be missoriented ( doing y' and lern another 12 EP sequnces is may be not the best)

5b. in 1 of 5 cases you deconjugate ( AUF + F ) because this will place FR edge

5c. Do EP now ! befoe deconjugation ( same 16 sequences but lookup is bit different )

I think this can be applied efficently (what's after 1.) to 50% of the EO cases.

I'm not absolulty sure if my restrictions under point 1. are all correct.

u' F R' F2 R U D B U2 B' R (there should be an y at the end, but the way I execute it I do the y already before the B)

or

L U L' U L U' B L' B' L' ( doing Bs like Us )

Didn't understand 'flipped FR' at first so my answer would be y R2 u U R U2 R2 y'

I think the bold one is fine

F' R U B U2 B' R' U F2 --> F' R U y R U2 R' F' U L2
R' D' F' D R' U R D' F2 --> R' u' R' u R' U R D' F2

I've only progressed by 21 algs within the past 2 days. Finals coming up, etc. I guess that's 60% now.

As for the above: I'll look into alternate edge methods. That really seems interesting.

Thanks for the algs!

I tested the L5E-Horizontal Algs , great work, but found on Error also added some alternativ algs, some of them should be faster.
the algs in brackets ( ) do not include the starting AUF , so please be cautious.

I also tried to name same triggers with in the RU-chaos: Like R U' R' U' R U2 R' = Wrong Sune or R U R' U R = Sune5 but it' still alot of "RU"
Maybe I should rember R U' R' U' R U2 R' U R U R' = R -3 +1 U2 -1 +3 -1 or just R -3 1 U2 -1 3 1 . What tricks do you use?

Thanks for the corrections.
I appreciate the help, really.

Hrm, I'll be looking into those algs later; I've been developing a little system in my head for edges that is similar to what I think yours may be.

Doing this intuitively may be nice as a new user or tester of the method, but apart from the first layer which should be block-built with the most adept skill level possible, I think that the method was originally proposed to almost be brain-dead on purpose. I think that the idea of just recognizing and doing sounds very nice; not having to do loads of conjugating during solves is useful for people like me who take time doing such.

 

[StachuK1992]

R U' R u2 R2 U' R' U u2 R2 is my new favorite alg that I've made by hand. (anti-sune + UF->FL)
Yet another update: 2/3 of the way done. I shall be done CO tonight, then I'll be looking into some stuff for intuitive EO+EP that I've been thinking about.

 

[oll+phase+sync]

For S' orientation my aktual favorites are

Antiniklas: R' U l U' R U l' - Preserves every Medges but one (BL)

middle fat: R U2 R' u' R U' R'

Also starting with learning just Sune cases would enable me to efficently use twostep CO.


I toyed aroung with L5E a bit and the only final (rather minor) thing I discoverd is how I handle the "bar U cases" (two opposit top layer edges are solved)

1. FR at UF

2. R'U' y

3. M'U2M U'F

altogether R'U' y M'U2M U'F this is not really any special but the mirror (just to save the starting AUF) R'U y M'U2M UF is learnd on the fly and in both cases I can watch how the piecec fall in place

 

[oll+phase+sync]

Following case - I call it: "crossing front back"
UB>UL>UR>UF R U' R' U' R U2 R' U R U R'

I remmber it like WrongSune + FixCorner (DFR) - wrong because the U turns go in the other direction.
The moment I dicovered this Name I was able to execute it faster


naming/memo system for the 5 cycles : The naming system I use is : look at the edges you see FR and UR , look where they have to go to , check if their pathes are prallel or cross or build a queue
So may names for the 5 cycles are: queue back, queue left , crossing front back, crossing front left, crossing foreigners, parallel foreigners
But may be everyone must find his own pictures.

3 - Cyclemania

one more Idea


If reaching EO step with one additional edge placed (be it U or E) all I need to do is:
1. execute one 3cycle to place any two edges (I prefer one in E one in U as this is easy to recognize)
2. solve the remaining 3 edges with another 3 cycle.
... There should only be few cases with "edges flipped in place" that resist this approach ... avoid ... learn


onstep further...

after CO I have a 1/6 chance to have correctly permuted corners anyway.
In this case I can just again execute an 3 cycle to place 2 edges at once ... and reach the case above

 

[StachuK1992]

In case you guys haven't seen, I made a new thread with everything documented.

Edit: I am about to explore the MU horizontal L6E stuff.
Any information you could send me concerning that would be awesome; perhaps we can find a better means of communication, though.
