# Human Kociemba method

Hi,

I am quite new to this forum and do not post very often. I am looking for some piece of information about a "human kociemba" method. I found no track of such a topic on the forum, so I ask the question. Sorry if the question was already answered (resulting in some noise on the forum).
Kociemba is popular among computer based cube solver, but several video show "real people" using it. I am wondering if some place explaining how to use it exists. This method (which has quite interesting math fundations) looks quite exciting.

Any help is welcome.

Human Kociemba has two steps. The first reduces to the second which uses <U,D,F2,B2,L2,R2>. The first phase is pretty hard but second is good.

Techically, Human Thistlethwaite can be viewed as Human Kociemba as well.

Kociemba solves the cube in two steps (like TheNextFeliks said), and Thistlethwaite solves exactly those steps - just with more substeps. And the "human" part is to break those steps into managable substeps, right?

Thanks too. Same question as above : do you have pointers to some place where this method is explained ?

Human Kociemba was the term I originally chose for another method I came up with (which I now call 3x3x3 redux).

I named it simply because both methods had two phases and I liked the idea of a two phase 3x3x3 method.

It came to a point where we were calling the method described in this thread "Actual Human Kociemba"

Sorry for the confusion guys! Everyone should probably stop using the old name.

Now I'm confused. So, which HK/HT method does the OP speaking about? The original one, like

or yours?

Seems he talks about actual Human Kociemba, i.e. reducing to <U,D,F2,B2,L2,R2> (or <L,R,U2,D2,F2,B2> or <,F,B,L2,R2,U2,D2>), aka Domino reduction. Instead of what Kirjava choice to call "Human Kociemba", namely reducing to <U2,D2,L2,R2,F2,B2>.

That looks really interesting. Can you provide the description of this method or give us pointer to information on it ? Thanks in advance :tu

I do confirm : what I am originally searching for is domino reduction (so reducing to <U,D,F2,B2,L2,R2>). I wasn't aware a reduction to <U2,D2,L2,R2,F2,B2> existed (and the nice thing with this forum is that you can learn many things there), but it interests me too.

There are a few threads about it I think but there's a recent one here

One way to Human Kociemba, a.k.a. reduction to Domino:

1a) orient edges + separate edges (put the four E layer edges to the E layer). This is intuitive, and works similar as EO-line in ZZ method.
1b) orient corners (two OLL with solved edges + orientation parity*)
2a) solve the cube as a domino (i.e., using <U,D,L2,R2,F2,B2>)
2b) permute E layer, which is the same as z + Step 4c of Roux method

*an easy algorithm for the orientation parity:
solve LFD + FRU: R U' L2 U R'

It wasn't a reduction to <U2,D2,L2,R2,F2,B2>. Parities like N perm existed that complicate things.

It was reduction to 3 colour cube first, then solve.

Are there any tutorials for that?
