Heise Method Discussion thread

[Athefre]

Here is a badly written page I made a year or two ago about Heise. It was made to show people how to avoid getting stuck, but almost nobody uses Heise.

http://athefre.110mb.com/Heise.html

There are some other things I could have added, but I just haven't felt like it. The main points are:

- Be able to plan the first two squares (2x2x2) during inspection
- During inspection, try to plan the corner you want to use after the 2x2x2.
- Use only five out of six colors while making the squares because you have to have one color left for the last layer. This rule is on his site.

An intro. and a few questions on the Heise method..

Hello, cubers.
My name's Justin and I'm a cuber from Singapore..

I've recently started on learning the Heise method because I felt bored.
anyway, I average about 40moves so far but would like to bring it down further..

And hence, I have a few questions to ask because I lack the understanding in some parts of the method..

Basic Questions:
What is the average move count that I should be getting for the "F2L minus a corner/edge pair"?
What is the average move count that I should get for a solve?

Forming the 2 corner/edge pairs for the Last Layer
Are there any tips or tricks that you use to spot the pairs easily?
Because I've noticed a few patterns with the corners that allow me to form corner/edge pairs quickly, but would like to know if there is a collection of it some where..

5Edges/2Corners-Normal Pair
Could someone explain F2-Conjugation and (B2 D')-Conjugation?
I've been trying to understand them for a few hours and I just can't wrap my mind around it ><

Heise is .

What is the average move count that I should be getting for the "F2L minus a corner/edge pair"?
What is the average move count that I should get for a solve?

There really is no answer for this that I can think of. It depends how good you are and how long you're spending doing the solves. Anywhere from 10 to 30 for the tripleXcross depending how fast you're going.

The only documentation that exists is on Ryan's website. Unfortunatly this crazy step is still somewhat voodoo to me so I employ a little trial and error. I only really use Heise for FMC.

Maybe you should make a collection for people?

I assume you understand how conjugation is like setup moves in blind. F2 and B2D' are simply setup moves that give you easier ways to commute pieces (turn bad cases into better ones) while keeping edge orientation.

Don't take my word for it though, I just read that now >_>

 

[Godmil]

I love the Heise method, but the optimal solution of the last ce pair and LL is soo tricky.
Concerning the F2L minus one pair, I'm sure I read somewhere that it was always possible in 20 moves, so I judge my own solves by how far under 20 I am at that stage... But I thought it was Kirjava who said it so I may be mistaken.
If you come up with any useful tips On this method it would be great if you could post them, There isn't a lot of info that I could find.

 

[LearningCode]

Oh..
So not a lot of info. up here, then? =/

If I were to 'make' a collection of things to look out for..
Where would I get those really cool java applets and images from? =x

I managed to get a 37-move solve today and I am proud of myself ^^
PS: I didn't know that the Heise method was for speedcubing..

I know that the F2 and B2D' are to make it easier to move pieces around..
But I still can't figure out when to apply them ><

[LearningCode]

Agh!
I just realized I don't have a website or a webhost -____-
And I am too lazy to get either.

Oh, well..
For those of you who are a bit curious as to what I've done..

Download the attachment ^^
It's got an explanation on The Edges-first approach and the Two-pairs approach for the LL.

The Two-pairs approach page has all (Should be all, I think..) 30 cases that could appear for the first pair.

It's pretty crude right now..
But it'll be helpful to some people, I guess..

I'll continue work on it another day, I've spent 3hours on this already -_____-
AnimCube took really long for me to figure out how to use ><

Anyone wanna' help expand on this?

[EDIT]
The examples may not have optimal solves, please don't hesitate to tell me about all the mistakes I made =x

[EDIT=2]
Anyone got an easy way to configure AnimCube?
I made a little something with javascript to help me quickly configure AnimCube with the facelets and Algorithms =)

But there must be a better way.. Right?

 

[kidrock2007]

heisemethod.zip not work ,why ??? utility ???

 

[LearningCode]

o.0
I used the default windows thingy.
Right click > Send to compressed ZIP

I'll try it again..
I can't save it as a .rar-file because the forums won't let me upload a .rar-file =x
And if the previous one did work, still download this one instead.

I just added the cases for when the corner is at the bottom corner..

[EDIT]
I haven't continued this after adding the bottom corners because there doesn't seem to be much interest, so.. xD

Need help for two pair approach in Heise method

In the third step for two pair approach I find it very difficult to make two pairs.

Please help me out.

 

[Godmil]

Check out this thread. Someone made some documents with lots of examples of this stage (I think).

Help needed with Heise method

Any experts on the "Heise Method" around ?
I need some help on the "down under" strategy for "inserting 3 edges" in the "two pairs" approach.
I can see what the algorithm does, but I do not understand it to the same depth as the other strategies used by the method, and I can't really apply it.

In addition I post some configurations I ran into where I can't see an efficient way out using the Heise method, maybe someone can advise:

1) U2 B F2 D' F D' F' D' F D2 B' F U2
2) B2 L F' L F L2 B R' U2 R U2 B U2
3) B2 D B' U' B D' B2 U R' B' R B R
4) L F' L D2 R' B R' U2 B' R2 D2

My goal is to be able to do a linear solve on every cube (ok 90% would be enough) with less then 50 moves (HTM) and only with algorithms I fully understand.

1) U2 B F2 D' F D' F' D' F D2 B' F U2
- z R2 U’ L’U2RU’R’U2L U’ L’U2RU’R’U2L U’ R2
R2 brings that UBR/BR non-pair to dFR to be more easily managed. L'U2RU'R'U2L cycles three pairs.

2) B2 L F' L F L2 B R' U2 R U2 B U2
- x’ I would just do L’U2L then swap the edges on U.

3) B2 D B' U' B D' B2 U R' B' R B R
- z’ R’U2LU’L’U2R LU2 RU2L’U’LU2R’ U’L’

4) L F' L D2 R' B R' U2 B' R2 D2
- z N Perm

I tried to do this using the pairs it seems you’ve created and staying with the method. When I use Heise, I try to avoid creating pairs made of the final F2L edge and the corner above it. Also, I've found that, if solving for speed and if wanting to stay strictly with the steps, it's best to simplify the two-pairs step to creating the two pairs then using these to finish:

L'U2RU'R'U2L
L'U2RUR'U2L
L'E2LU'L'E2L
L'E2LUL'E2L
N Perm
J Perm

"Down-Under" looks like it's just an option. Unless someone knows they are supposed to apply two 3-cycles but is struggling to see where to start them, it's best to stay with pair 3-cycles for normal pairs.

1) L' D F2 U' R U F2 D2 L B2 D Handy ZBLL
2) B2 R B' L' B R' L B2 Hard to see linearly
3) R' B'
R' B R2 B' R2 F' R B R' F R Anti-Heise
4) B' L B2 R F' D2 F R' B2 L' B L Handy ZBLL

Not really Heise mindset, I guess.

 

[ortwin]

Thank you for your suggestions. It will take me some time to see what I can learn from these.
Also I think I must realize that I can run into situations where I can't reach my goal (sub 50 moves) with this technique.

I suspected something like that too, I will now also try to avoid this type of pairs.

Ortwin,

you may also want to check out the weekly competition FMC results.
There you will find multiple solutions for the same scramble.

Especially the FMC eperts like Irontwig, Guus, Okayama and Kinch will often work from F2L-1 to "leaves 3 corners" via the two pairs approach.

I have been planning to study this for way too long (and still haven't gotten to it) as I typically work up to "5 corners left".

 

[ortwin]

Cubenovice, I know those competitions, once I can do a linear solve in under 10 minutes with less then 50 moves I will contribute. Is there no forum for discussions amongst members there?

 

[Cubenovice]

You wil find some discussions in the weekly comp but more so in the FMC home thread that is stickied under the "puzle theory" subforum.

In the FMC home thread you will find some discussions on specific solutions.
" How to find a good finish " for ... is quite a common question there

Don't let lees-than-perfect results keep you away from the weekly comp! I have participated in 3x3x3 speed with a 50s average, who cares???

Definately participate in the FMC event:
Comparing your solution to those of others is a great way of learning.
Also because you have already spend time on that scramble you will be more motivated to study better solution.

 

[ortwin]

@Cubenovice: oh now I see what you really meant by the weekly competition: the one in this forum, I thought the one I knew so far: http://fmc.mustcube.net/ There is also an archive of competitions on the website of Ryan Heise, but the presentation of the solutions is not very useful (only the applets, no FBRLUD notation ),

 

[Cubenovice]

yep ,
I meant the one on this forum. But offcourse mustcube.net is a great resource tooas you have over 300 scrambles with various solutions.
