Just Another Rubik's Cube Solver

[Johannes91]

http://laire.dy.fi/jarcs/

It's a collection of partial solvers, at the moment there's Petrus S1, 2x2x3 block, Cross, and XCross. Some solvers that I plan to add: Roux S1, Roux S2 (using <U,R,M>), MU, Petrus S4, and maybe Kociemba's algorithm for the whole cube.

[edit 20090322]
I rewrote the solver, the new one is a bit more general. The list of solvers is now:
Petrus: S1, S1+2 (aka. 2x2x3 block), S2+3, S4.
ZZ: EOLine, 1x2x3 block after EO line.
Fridrich: Cross, XCross.
Roux: S1 (first 1x2x3), S2 (second 1x2x3), S4 (MU).
Full Cube: A pathetic implementation of Kociemba that works but is really slow, mostly because I didn't want to use big tables.
[/edit 20090322]

It understands most of Heise's simulator's default keys. You can also use Shift to rotate the whole cube and Alt for wide turns.

Edit: It seems like all versions of IE are failing. Too bad.

Man that's impressive. Nice work!

 

[Robert-Y]

That's great!

Btw, what is this: for($"=@_=split??,"Jrsk an treP rehlohacteu,";$";$\="\r"){$\.=$.=chr
32+95*rand,$_-$"or$.ne$_[--$"%2?-$"-1:$"]&&$"++for++$|..$";print}<> ?

You ought to run his. Preferably on an old or busy computer, or modify the code to slow it down.

hr.mohr, Roberty-Y: Thanks! I'm writing it mostly for myself and fun, but it's nice that someone else finds it useful, too.

In case it's not obvious how to do that, there's also a really slow JavaScript-version.

Btw, who's at 128.12.98.61? Surprising how few people have checked root before.

 

[Stefan]

nslookup says Stanford, so I guess Lucas?

 

[Athefre]

I plan to add: Roux S1, Roux S2 (using <U,R,M>)

The important r/r'/r2 won't be included?

MU

Is this for Step 4? For it to be very useful you should add an option for it to ignore center orientation and still be able to orient edges correctly.

Yes I'm saying this because of those two topics Gilles, Cubacca, and I were posting in

Indeed. Not sure why people wouldn't want to.
If you have a timelog, you might also be able to guess why I went there.

They would. I meant just that the solutions would never break the first 1x2x3 block.

I was thinking of doing it in one step because the number of cases is so small. But maybe 4a-4b-4c or some other 2-3 steps would me more useful? In any case, the solver requires some modifications to properly deal with moving centers, and that'll probably have to wait a few weeks.

Yup.

It might not matter a whole lot if it has the feature (it would just be another nice feature for your page ) because cubacca said he is working on a program just for finding short solutions to specific cases in LSE.

BUMP

It looks like the server hosting the laire.dy.fi domain is down. The domain itself returns a DNS error. Until June this year the domain had been pointed at the IP 80.248.244.31, but requests to that IP are now timing out.

@Johannes, is the service now located elsewhere, or have you decided to discontinue it altogether? If you can get it up and running again that would be great!

 

[Kirjava]

It moved!

 

[Cride5]

Thanks

... but the new address also appears to be timing out. The domain is fine - resolves to 128.12.98.61, but it looks like the server is having issues. Guess I'll try it later...

 

[Johannes91]

Yeah, I moved it and was too lazy to set up a redirect from the old domains.

There was some power outage ~12h ago which is why the site was down today. In general it should be up fairly reliably.

Anyone know what happened to this? It's been down for a while. I found it really useful.

Dunno. Back up now.



Edit: I don't follow this forum much but I get email notifications for private messages, so they are better for reporting problems.

It's down again(404 Not Found). I find it very helpful for improving blocks and the MU solver is great!

and I sent a private message as well.

 

[Johannes91]

Thank's, now it's back up (again!). Two servers have died while hosting this thing.

Thank you very much!

It's down again...
