SOAP 2x2 Method

[Zarxrax]

Now that IS quite interesting.
It might be worthwhile to try and make a fully 2-gen version of soap, just to see how it turns out. I would bet that some of the algs might be stupid-long, like 10 moves though.

 

[FatBoyXPC]

It would be a bit similar to Sortega at that point

For your bar/no bar subsets, you could also call them chameleon/headlights subsets (for on bottom). Really it's just semantics and doesn't matter, but I suppose fits slightly better (but I suppose that's just a matter of preference ).

Cool job Justin

Who is Ortega ? nickname ? human ?

Here the operation of the 2x2 I'm the creator

One can see without using your cube it is difficult to solve.

Great method for fewest move challenge

method (1982)

And if you look to your left, you will see a crazy guimond...

OMFG JUSTIN GOT HIGHEST PRAISEEEEEEEE

 

[Zarxrax]

Just to make sure here,
If you have a 2gen alg that swaps 2 pieces on bottom, then you get a diagonal swap on top.
And if nothing is swapped on bottom, then nothing will be swapped on top?

So far this has been whats happened with a few algs I checked.

So if this is indeed the case, would it actually be best to try to generate only algs that don't swap any pieces at all?

 

[Zarxrax]

I finished generating 2-gen algs (with no regard as to whether or not they swap anything), and some of them are pretty nasty. Lots of 9-move cases and 2 11-moves.
Average across all cases is 7.35.

So if this is indeed the case, would it actually be best to try to generate only algs that don't swap any pieces at all?

No, prediction is equally easy in either case, as long as you know what the effect on the DR corners will be. It might be useful to have an alg for each case though.

 

[Zarxrax]

Ok I updated my algorithm list with 2-gen algs for every case, and an indicator about whether it causes a swap.
I'll try to add alternative 2-gen algs for every case (if possible) soon.

It would be great to know if anyone else commits to learning this along with me.

Just got my first 2x2 and just couldn't decide which advanced method to go for. I like the PBL finish and not having to be dealing with opposite colours, plus the low number of short algs in this method is nice. Also with a few attempts I've decided it is easy enough to recognise the orientation during inspection. Ok, what the hell, I'll learn this method.

Thanks for listing all those cool algs Zarxrax. I'll learn the first two subsets this week. Then I should be on track to learn the rest before the end of Feb.

 

[FatBoyXPC]

Godmil learn ortega first. Rowan can easily sub4 Ortega, but that takes a good bit of practice. Ortega will get you used to PBL recognition, and you don't have to learn any other algs (than PBL).

 

[Godmil]

Thanks fatboyxpc, I already learned Ortega, only took 30mins or so. I think it's a lot of fun, which is why I'm going to start on SOAP, cause it feels like a nice extension of Ortega. I could spend some time just getting fast with Ortega, but I like jumping in at the deep end (which is why I learned full Fridrich before I was sub-50), I find it more interesting

EDIT: of course Ortega will also be my main method while I'm learning soap, so I'll still get my PBL practice in

 

[FatBoyXPC]

Ortega is just learning 5 PBL cases, 2 of which you (should) already know, one being 3 moves, one being 3 moves + AUF + repeat those 3 moves, and the last being move + F2 + undo move. PBL is quite easy to learn

I suggest learning the SS subset first. Learning multiple 2x2 methods will really help you out in the long run, if you plan to get good at it. This also means learning Guimond, SS, etc. Learning full Guimond isn't difficult, and can get you a sub3 average with enough practice. Honestly, if you want to get really good at multiple 2x2 methods, talk to David Woner.

It seems that the link for the SOAP lags is not working... Can anyone send and updated one?

I found this website with the algs on it. Out of curiosity, why are you looking to learn it? I think it's generally accepted as an inferior method to CLL, or onward to EG, or *ahem* HD. On a side note, welcome to the forums!

 

[Roux_Over_CPOF]

Thanks for the link! I want to learn SOAP because I thought it sounded interseting, after looking more into it I found this discussion and decided I wanted to learn it. (Also there are only 30ish algs!)

 

[VarasanoNotOrtega]

here are all of the algs for the SOAP method..
I think it is better than learning CLL. With CLL there is a recognition step you have to do the first 4 corners then look at the last 4 corners. In order to be really good at CLL, you ahve to be able to 'look ahead" and see the cube state after your first 5-8 moves solving the corners.

With this method, you do your looking ahead in the preinspection phase. You see the first step which is usually 2-3 moves literally. you will be able to see the case for step 2 because it's easy to visualize 2-3 moves... a LOT easier than visualizing 5-8 moves. SO essentially, step 1 and step 2 are done in one look, as ONE STEP.

1. the first step is to put 4 corners on one side of the cube with 2 of the corners oriented. The permutation doesn't matter.
2. the second step is to perform one of these algs (see attached document) which is 7 moves on average
3. the third step is PBL.

on the right is a diagram showing where the corners are permuted on both the top and bottom.
If you get good enough with this method, you can do 1 look solves, because you can predict the PBL case

I have done 2×2 like this before...
This sounds a bit like something I saw Chris Olsen talking about in one of his YT videos back in the day
