Random Cubing Discussion

[Cale S]

Whats to stop me from organizing a comp and calling it US Nationals 2016 on January 2nd with me and some other random cuber as the only organizers?

The WCA has to approve competitions, and they probably wouldn't approve that for some strange reason

My point being that they have no regulations about preventing someone from claiming the right to host a national competition. At least not to my knowledge.

There are no regulations against odd competition names, but until recently many of those were rejected.

New metric idea for Square-1: "qtm". / counts as 1 move, (0,x) or (x,0) counts as x/3 moves rounded up. So /(3,-3)/ is 4 moves, as is (6,6). Alternately, / counts as 2 moves - maybe some Square-1 experts could chime in on whih makes more sense.

I don't really qualify as an expert but I think that ATM (where any moves on the the same axis count as one-ie U D counts as one moves) as most of the algs or just moves in general will be doing double moves (slice moves depending on how you look at it).

If this is for measuring TPS more accurately (which I assume it is), then I think each (x, y) pair should only count for the bigger move. In my experience, the time to execute (3, -3) would be closer to (3, 0) than to (6, 0). Also I feel like / should count as 1 move. / is technically more turning, but I feel like it's faster and easier than an equivalent layer turn.

I agree that counting pairs of moves makes more sense, yeah - in practice, if I do a (3,6), I'm not really gonna do U D D, I'm gonna do (U D) D at worst.

I think I agree that / feels more like 1 move than 2. Then again, QTM on 3x3 equates R to U, and R2 U R2' is definitely slower than R U R' on a 3x3, maybe it should be considered 2 moves. But I think we're getting more into the arguments between QTM and HTM on 3x3 at this point. I'd probably say that the equivalent of QTM should be 2 for /, and ceil(max(x/3, y/3)) for (x,y); for HTM, it would be 1 for /, and 1 for any (x,y) pair (aka, the WCA counting system).

Taking the max of x and y sounds good. I was aiming for something a bit closer to ETM - something which would give a very rough idea of how long an alg really takes to execute.

In that case, I think max is probably your best bet, yeah.

As for moves, because of my turning style, I find that (-4,y) (at least once in cubeshape) feels like 1 move, while (4,y) tends to feel like 1.2-1.5. I don't like doing anything more than |3| on D - in fact, I think that other than ABFs between steps and maybe 1 move in cubeshape, I just don't do anything more than |3| on D. So ceil(x/3) is probably close enough, but just some feedback on what I subjectively feel when turning. (Of course, the correct thing is to film myself doing moves, both in algs and in solves, and see how long everything tends to take. But I'm lazy )

Which is the best CoLL subset to start with? I know most people will save Sunes and Antisunes for last so H, Pi, T, L, or U?

I did H first.

H or Pi have nice algs and easy recognition.

 

[TDM]

I think L has the easiest algs by far - all are 8-9 moves except triple (anti)sune. H is a smaller set though, so I think many people learn that first.

I learned H first. only 4 algs: F triple sexy F', double antisune, sune cancelled into niklas, and F insert U R U2 R' U' sexy F'.

The accomplishment thread is a pretty cool log of everyone's progress, I was wondering if there was an easy way for me too get a list of all of my posts. It would be cool be if I could make a log of all of my progress.

Thanks, I knew about the search thread function, but I didn't know you could search by username.

Had my Christmas party last night, showing off the usual (3x3, 3BLD, 4x4, 5x5, couple of random puzzles). Turns out, red wine is not a very good lubricant. Just my stickerless Gans 357 though so it's easy to clean out.

Has anyone ever made an icosahedral cube?

Well if it's icosahedral it can't be a cube but there are icosahedron shaped puzzles like this, this, or this
