New2x2 speedsolving method

[JeffDelucia]

Today I was looking for a 2x2 speedsolving method to switch to. I watched a video by Weston about various methods. It made me think about combining the more appealing aspects of different methods. So heres what I came up with. First you make a face of opposing colours like in OFOTA. then you orient the top face. Then you permute both layers and put all the pieces in the correct layers. Sooo what do you guys think?

I'm not sure I understand you correctly.

1.) Make a face of opposing colours.
2.) Orient LL.
3.) Separation PBL?

I had that same idea once, but I think someone told me that there are a very large number of algs for that last step

 

[joey]

Wasn't it 2k algs?

Also, it's a pretty obvious method, but people have already dismissed it because it's not really usable.

 

[Kirjava]

I think you should start trying out your random ideas to see if they actually work before telling us about them.

How many cases is it? Do you have algs? What's the movecount like?

I thought of this method as a 2 look one a few days ago, it has 1,2xx algs for the last step alone, and the first step is shared with guimond.

I have the same idea, almost...
Make a side with two opposing colours (eg two white, two yellow, preferably adjacent) then orient top layer, then bring the colours to their respective sides (eg, if you had yellow and white at the bottom, and the top, you bring them to their sides. Is that orientation? o.0 ) Then PBL like ortega... not very effective, though. Can get like 5-7 seconds on it though. First face is very fast.

 

[joey]

Eh, that method sucks. I use it sometimes, but it's bad.

 

[Feryll]

For the last step:

That's 101 algs to learn, the number is quite large but not unmanageable. Recognition would be quite messy though.

 

[CubesOfTheWorld]

It's kinda like ortega, but with extra turns for no reason.

... and the first step is shared with guimond.

It's not the same as Guimond.

In Guimond you start with 3/4 of a face of opposite colours (most scrambles have this already if you're CN), and then do a short alg to build *2* faces of opposite colours. Separation is again a very short alg and brings you to PBL.

Guimond is the best PBL-based 2x2 method IMHO. It has a reasonable number of algs, with great move-count. Separation prediction means that if you're good you can plan all your moves to PBL during inspection.

Learning tonnes of algs for a PBL-based method seems a bit pointless, when you're competing with something like CLL/EG.

How do you predict separation? I've seen lots of people mention it, but I've never seen anyone actually say how they do it.

How do you predict separation? I've seen lots of people mention it, but I've never seen anyone actually say how they do it.

I have to say, explaining looking ahead and predicting moves over the internet is really, really hard. For me at least, it is a mostly intuitive skill I've learned through doing hundreds of solves and practising predicting steps.

I don't have the time right now, but I'll be writing up a few threads/posts about using pre-inspection wisely for 2x2 and 3x3 in the near future...

sweet, looking forward to that.

Hes just trying to run it by some people and get some feedback, not like hes trying to replace CLL or somthing, just putting out an idea.

Are we not giving feedback?

 

[Weston]

This is just Guimond, but with a harder first step, and more algs.

 

[Tim Major]

It's kinda like ortega, but with extra turns for no reason.

That's... not really like Ortega at all. It's combining two steps of Guimond into one.

Edit: Weston: you sure? Seems like waaay more algs. Combining the part where you move the opposites into diffferent layers and pbl should be way more algs.

Okay. I'm gonna be lazy and do a quick upper bound on the separate and permute algorithm count.

7! different permutations of the corners, since one corner can be assumed correct.
Divide by 4 if you're willing to allow AUF. Divide by two if you allow x2.
7!/8 = 630.

Lots.
