Volunteers needed for cross solving study

I hope you will do the same for a 2x2x2 block

That'd be *a lot* harder (and this is a huge understatement).

Indeed...

The only way I can think of is to go over all 43.252.003.274.489.856.000 cube positions and do 8 table look ups for each of them.

If you would also add a text-based version (no GUI), I could run this in background on some servers..

Be very carefull about doing that. Servers are typically not meant to run privately made programs like this one. If these are your own servers, that might be ok, but never do that on your bosses servers without (written) permission

Dont worry, I am allowed to do that

The client is running on my pc now. Too bad it requires a "cmd" and a "java" window to stay open.

Yeah, the cmd window is a bit annoying. If you want it to disappear, edit the batch file to make it look like this:

start javaw ....

instead of this:

java ...

As for the application window itself, I thought it would be nice to get at least some feedback of what is happening.

Hi Lars

Are you ultimately going to calculate an upper bound for the whole of CFOP?? Sounds like a daunting task to me

I have seen some estimates .. ranging from about 55 - 60. But that was for average solves !!

Will leave this running while I'm at work, but with my Athlon XP 2400+, I don't know how much help I'll be.

Any help is greatly appreciated. Thank you!

 

[Bounb]

Excellent idea.

I very much like your approach to this - with the '@Home' style cumulative processing power program. I'll leave it running for a bit. Look forward to seeing the results

And here's one where each 2x2x2 blocks requires 8 moves: B' F R D' U B2 R2 B' L' R D F2 U L2 R2 D' R2 D'.

this is the ugliest scramble I have ever seen.

Really? Maybe you should try it on a 2x2x2 I think the WR can be broken with this scramble

Actually, I think you should use this command:

start /belownormal javaw -cp colorneutralityathome.jar -Dmode=online -Daddress=78.21.73.117 -Dport=8080 cross.gui.CrossSolverMain

That way your system will be much more responsive for your daily work.

That's good feedback Arnaud, I didn't realize you could specify a priority like that. I will change it in the next version.

 

[ShadenSmith]

I'm helping as well.

 

[jazzthief81]

Very nice, I'm looking forward to those results as well. Especially quarter turn metric.

Of course, it's easy to find single cases where the white cross can't be solved in under 8 moves but the yellow cross is
already solved.

Are you sure? Can you show one?

OK, I have to admit that I wrote this down without really thinking about it. The point I was trying to make is that it's easy to find cases where your normal cross is quite hard and on another face it's (almost) solved.

But because you insist, Stefan, here it is and it wasn't difficult to find :
B2 D L2 R2 U R2 D' L2 R' F' D' L R2 B2 F' D2 L' F2 D U2

Scrambles like that tell us that color neutrality is great.

In that case, you can download the client application again. I've added a text-only mode for running in headless environments.

The client application now also starts at the lowest priority right away.

Kind regards,
Lars

Now try this one:
D2 L' D2 F2 R' D2 B2 F2 R2 B' D U F L' R' B U2 F2 D2 R2

I happen to think I found a fast, easy cross on these scrambles upon trying them. I might not even mind having an average of 12 solves with such crosses.

 

[Lofty]

I'm on my second packet
And I would be interested in doing it for 2x2x2 blocks, though I'm only opposite color neutral and not even sub-40 OH with Petrus it still leaves me all the 2x2x2 blocks to pick from.
We should do a similar thing with ZBLL. I would love a massive table with tons of algs to pick from for each case divided up into LUR, RUD, RUF, optimal, etc.

I don't think coming up with an upper bound for the whole of CFOP is a daunting task. Finding the best (lowest) upper bound for the whole of CFOP might be, but first you would have to define exactly what you mean by that.
