Thank you for the test.
I updated the JOGL.

I think it's OK for Windows and Mac with intel CPU.
I couldn't find a native library for Power PC at the JOGL home page.
It looks that PowerPC is abandoned...

The old version is archived here, in case the new one doesn't work.

This is simply because the old page is still cached on your disk.
Only you have to do is relaunch your browser.

Ok somebody help me. This is quite off topic but it's my java applet or something taht doesn't work anymore.
All of a sudden. It loads and than there's nothing. Same with internet explorer (I have been using firefox). In the internet explorer there is even this java sign and a big circle around it that simulates a loading status. Then it just disappears and nothing happens. Maybe the puzzle is even there but I can't see it.
Has anyone ever had this problem?

Eerr. I just played another java game. It works. It definetly is a java game because it does not work anymore as soon as I deactivate Java in the options.
When I reactivate the game works again. Is it the site of the gelatinbrain applets? I guess it isn't unless noone can see puzzles anymore.
Man I wish things would just work on a new computer.

First off all I am sorry for the triple posting here. After installing an update for java the puzzles work again.
I guess if this new update hadn't been there I would still be becomming desperate.
I don't know what that was but it works again. Hopefully there will be Java updates every 2 weeks just in case it suddenly stops working again so I won't have to wait too long until it does work again.
Everythings fine now :wink:

it didn't work at first, but updated my java and it's fine. I immedeately had a go at the circle FTO, and solved it in too much time because I had dinner in the meantime, and way too many moves because I had to figure out some algs while scrambled. Similar to the FTO as the circle cube is similar to the 3x3x3, but with one more annoying thingy :wink:

1.4.6

As this puzzle has more pieces (470) than any other Gelatinbrain puzzle, I thought it would be fun to show screenshots of the main stages of solving it. I used the method outlined here. I built up 5.6 faces of edge-aligned kite pieces using blockbuilding sequences, then I switched to a mixture of moves of the 5 "free" edges and cycles to get to 7 faces + as many as possible correct out of the last 5 faces. N.B. When committing to using commutators and setups only for the remainder of the solve, make sure you've made an even number of moves! (If we didn't know the length of the scramble we would need to make a dirty solve, perm only, of the corners at the beginning; but because we know the scramble length is an even number, we know an even number of moves results in an even perm of the corners.)

I found setting up pieces more of a challenge with 1.4.6 than with any other puzzle I've solved so far in Gelatinbrain. Fun but very tricky. I solved it on and off during the day, taking around 12 solving hours plus extended breaks. Here are the pics:

Hi, Evgeny. I took a look at 1.4.3 again. First I found another pure cycle, a commutated commutator of length 34 similar to algos that you posted in your solution. This made me happy, because I spent hours looking for an algo like that months ago and failed. Then I wondered if I could find a shorter length dirty cycle, taking advantage of the fact that there are two distinct sets of 60 pieces. In the picture below, 3 pieces from one set have been cycled in 22 moves, and the other moved pieces all belong to the other set. So a fast solution would be to use this algo for the first 60 pieces, then swap to pure cycles of 30 or 34 moves for the other pieces.

Can also move d instead of D for a slightly different cycle.

1.4.3 continued...

I experimented some more today, to see if a pure cycle of 26 moves is possible. It turns out that it is:

I just saw that you solved the 1.4.6 finally! Than I checked this thread and yep your post is of course there already. I adore you for having solved the 1.4.6.
Amazing.
But seriously. I just would like to have that confirmed: You know that the puzzle was scrambled by an even number of moves and that tells you that you won't have a parity of the corners? But when you start solving you do the 501st move. Since you can't solve the puzzle by undoing the scrambling obviously.
First: have I understood you right with this?
Second: Does this work because you from the beginning only do algorithms/sequences of even moves to solve the puzzle?
Because when you just start messing around with it, maybe trying to solve some pieces intuitively untill you get to the point where you need a serious method (whenever that is) the parity might appear right?
Hopefully this post isn't superflous I might not be able to understand the answer.

They are good questions. I didn't think about the corner perm when I started, so I had to undo nearly 100 moves when I was a few moves from reaching a position like the first screenshot! Every move of 1.4.6 swaps 3 pairs of corners, moving from an even perm to an odd perm or an odd perm to an even perm. So from the solved position, including the scramble: odd number of moves = odd perm, even number of moves = even perm. You can solve however you like up early on; the only problem is proceeding so far that you find yourself on an odd total with a lot of pieces solved, then any move you make messes up several previously solved pieces.

To illustrate, referring to the first 1.4.6 screenshot, I started with White and then completed Brown, Turquoise, Dark Green, and Purple using blockbuilding moves. The 3 Blue (edge-centered) kites nearest White were tricky but doable, but trying to solve the last 2 Blue kites without messing up Brown or Purple was a nightmare, so I cycled them into position. I solved the 5 Dark Blue kites using a mixture of cycles and moving edges bordering Yellow, then I was limited to a small number of alternating moves of Yellow/Orange and Yellow/Light Green to arrive at an even number of moves while trying to maximize the number of correctly positioned Red, Orange, Light Green, Pink, and Yellow edge-centered kites. From that point, I used commutators and setups only.

Edit: To try to answer your second question more clearly, commutators and setups are always an even number of moves. Where S is a sequence of moves to set up pieces for cycling with a commutator, solving exclusively with commutators always involves sequences of the form S (P Q P' Q') S', which are all of length (P+Q+S)*2. Regardless of how the length of P, Q, and S vary, the sequences are always an even number of moves. So if you start solving exclusively with commutators from an even perm, you're safe.

Recently I have been thinking about solving relationships between Skewb-like puzzles and I thought it would be interesting to summarize some of them:

The Skewb Family

Deep cut(ish) puzzles

3.2.1 Skewb

4.1.1 Skewb Diamond

5.1.1 (‚Č°Pyraminx)
5.1.2 Pyraminx
5.1.3 Halpern-Meier Pyramid

Other single cut puzzles

3.2.2 Master Skewb (reduces to Skewb)
3.2.6 Rex Cube (==> Pyraminx)

4.1.2 Face-Turning Octahedron (==> Pyraminx)
4.1.3 Dino Octa (==> Pyraminx)
4.1.4 Dual of the Master Skewb and the Master Tetrahedron (==> H-M Pyramid)

5.1.7 (==> H-M Pyramid)
5.1.8 (==> H-M Pyramid)
5.1.9 Master Tetrahedron (==> H-M Pyramid)

----------------------------------------------------------------------------------

My recent realization was that 4.1.4 can be reduced to the Halpern-Meier Pyramid: when you've solved 4 non-adjacent face centers at the beginning, those groups of 7 pieces are the H-M Pyramid corners, while the remaining little center pieces are the H-M Pyramid centers. Then pair up the edges and solve the H-M Pyramid (turning only the 4 "big center" faces).

On my mac the applet no longer works :(

The last thing that my computer says is:

Code:
Applet org.jdesktop.applet.util.JNLPAppletLauncher started


And in front of me an empty white window (except for the text below where the applet should be.)

I have checked for updates with java and apparently i have the newest version. I don't know what to do. :(

When playing around with this puzzle today, i found a nice algorithm that does this:

Attachment:
File comment: 1
algo1.gif
algo1.gif [ 29.55 KiB | Viewed 2375 times ]


The algorithm is: (L' R L R')x15
Probably not very optimal, but im still learning :lol:

You can see that since the pieces go to where they do after this algorithm, if you do it again, you will get the eight pieces flipped in four pairs of two, as so:

Attachment:
File comment: 2
algo2.gif
algo2.gif [ 29.08 KiB | Viewed 2375 times ]


The algorithm is: [(L' R L R')x15]x2

So with this algorithm, you could solve it up to having the small triangular corners remaining. Now to find an algorithm for them...

First of all, test the following site on your Mac, please.
https://jogl-demos.dev.java.net/applettest.html
Do you see an animation of gear works?
If this site doesn't work, I'm afraid your OS is no longer or not yet supported.
If it's OK, I will check for the native library for your machine.
Let me know the version of your Mac OS and the CPU(Intel, Power PC etc)?

but then after 10 minutes, no progress made. Is it taking a while to load, or can it not go further.

When I'm using this applet on my Mac, it basically works but with the following small glitches.
1. Under safari 4.0.4, if the applet is in tab#1, then I switch to tab#2, then back to tab#1, the applet disappears leaving a white space in the place of the applet. The only way to get the applet back is to refresh the page, but then the puzzle is reset at the same time.

2. Under firefox 3.5.5, if the applet is in tab #1, then I switch to tab#2, the two squares showing the puzzle is over the content of tab#2, as in the following snapshot, where the squares are over the google page.

If I go back to tab#1, I can continue the puzzle.

3. Under both safari 4.0.4 and firefox 3.5.5, when the puzzle is solved, the dialog asking for name is behind the two squares, as in the following snapshot.

I can still write my name and press "confirm", because the button "confirm" is luckly in the middle.

I can see the gear in the page https://jogl-demos.dev.java.net/applettest.html. It works. My OS is MAC OS 10.5.8. I hope this information helps you to debug. Thanks.

Hooray!! I just solved 1.3.5c In 1h 58m 46s and in 1102 moves. Not too happy about the move count, but happy enough that I solved it at all! :lol: At one stage i was confused, because i was on the last layer and could see only 2 corners needing to be swapped, and got really confused, but after examining the puzzle piece by piece, i realized that on another face i had two corners swapped also! So I put them on the same layer and did megaminx style PLL with 2 pairs of corners. Here's it solved.

I have a question about solving the GB applets...

HOW DO YOU DO IT?

I don't what it is, but I can never seem to get the right slice to turn the right way. I did the 2x2x2 earlier and took me almost 3 minutes. :(

You put your cursor over the face/edge/vertex you want to turn until the section that you wish to move is surrounded with a black line, and you left click for counter-clockwise and right click for clockwise. Shift+Click allows you to do a slice turn. Thats as clear as i can make it :wink:

Try the dino cube. I figured it out on GB by myself and within about 10 tries got down to 19 seconds! :D

I was solving 3.4.5 today, trying to beat my last time/move count, and almost finished, I ended up with this parity:

EDIT: Instead of double posting, I'll just edit my post.

Just finished the Circle Megaminx/PyraCrystal. Spent about 10 mins trying to remember how to do a 2 edge flip on the Pyraminx Crystal edges. Anyway, finished it in 31:50, and 766 moves. A picture:

I solved that one and the circle megaminx too. I'm at a tie with Noah right now.

EDIT: and now I have surpassed him. But I'm sure he'll beat me easily if he ever comes back :wink:
This is because I did 1.1.24:
Attachment:
1.1.24.JPG
1.1.24.JPG [ 71.35 KiB | Viewed 2382 times ]

solution outline:
1.solve like a megaminx, with the corners like the megaminx corners an the inner corners like megaminx edges
2.pair edges and inner edges, solve like pyraminx crystal with ONLY things like R'LRL' and such, because the circles don't like pyraminx crystal setup moves.

Had a go at the Circle Pyraminx Crystal, got it done in 1:24:46 and 1499 moves. Took a while understanding how to pair up the last edges and inner edges but once I figured it out I took about 10 minutes to finish it.

Megaminx Corners and Inner Corners (Megaminx edges) Done:

Mark, it seems we are on the same pace, using similar method. I remember when I finished the megaminx steps, it was about 35 min. Eventually I'm just 1min faster than you :)

The megaminx edges (i.e., the inner corner pieces) are really hard to find. Very counterintuitive...

I spent so much time looking over and over for the part until I realised I had looked at the wrong corners to start with and was looking for a part that didn't even exist :lol: . I don't think I will give the last circle puzzle a go. I cant even solve the non-circle cornerless version (aka. starminx) :roll:

I've just had a go at another puzzle on GB. I'm not smart enough to do the really hard ones so I had a go at the easy icosahedron. I think that I solved it but the timer continued. :? I know that there are identical pieces, but surely this counts as solved? :(

You still need to cycle those four pieces. You won't be able to swap the two pairs one at a time because of parity issues, so that means you'll have to exchange a few of the light blue pieces between teh light blue faces. If that makes any sense... it's been a logn time since I've done anything on GB.

On both the light blue faces you have the light blue+Dark blue piece swapped with the light blue+violet piece. If I got this I would do simple algorithms that cycle 3 pieces on a side. Say 2 adjacent corners are L and R. then doing L' R L R' will swap 3 pieces around a face. I would continue swapping pieces around the puzzle until I get to the other side, where I can then fix all the edges and finish solving it.

I see my mistake now! I must have not paid attention on one side and so I couldn't solve the other. I'll try again. :oops:

Thanks :D

EDIT: solved!

Now, onto some more tricky stuff :D

I found out an algorithm that does the following on 3.3.2, 3.3.3, 3.3.4(moves inner corners with center), 3.3.5(inner corners move with center also). It also works for 3.3.6, but some inner edges are moved too:

The algorithm is:

[ (RU LU RU LU) (FU BU FU BU) (LU RU LU RU) (BU FU BU FU) ] x7

Don't know if this is any help to anyone, just thought I would post it in case it is :P

-Mark- :)

EDIT: Just found another algorithm, does the following on 3.3.3(Most of the other edge turning cubes too.):

I eventually solved 1.1.25, the last circle dodecahedron. 2 hours...... Unlike the other circle puzzles, 1.1.25 does not have any coupled pieces which always link with each other. Every piece stands alone. It's like an extension of 1.1.4.
