It was from an high 18s session: this was the first average of 12. I had 19 parities in total, so slightly fortunate, although I seem to be coming to the conclusion that CCT scrambles result in me getting parity <50% of the time (assuming parity is 50:50).

[Mike Hughey]

(Hint: none of them are Magics. Those aren't puzzles.)

I disagree entirely. They are puzzles. It's just that, for some strange reason, people never bother to scramble them.

My daughters and I have been having great fun this week solving scrambled Magics. I think I'm getting almost as good as Arnaud at it now. There are still a few cases I have trouble with, but mostly I know how to solve them pretty well. My oldest daughter Marie has gotten pretty good at solving it once it's flat, but she still has a lot of trouble getting it flat.

Oh, and qq, nice relay. (I didn't guess right.)

6:17.03 7x7 single! Down from barely sub 7. Maybe it's time to try my first average eh?

 

[Robert-Y]

Mu guess without looking at spoiler:

2x2x2, 3x3x3, Clock, Pyraminx, Snake

EDIT: Just peeked, I got 2 wrong

If magic isn't a puzzle, what makes you think snake is? Just pointing that out.

I didn't really think the Rubik's snake is a puzzle, I just couldn't think of any other puzzle at the time

Yeah the current scrambling method results in parity about 1/3 of the time. Andrew might be able to explain it better than me, but I think it has something to do with scrambles being random moves and not random state. Not that I'm complaining .

The same can be said of megaminx. Unless I'm mistaken, its impossible to reach all states by the current scrambling method. However, it looks scrambled enough, so nobody cares

 

[Truncator]

First sub-30 3x3 solve: 29.03! ^^

 

[qqwref]

It's not even remotely close The WCA scrambler can generate about 1.5 x 10^23 positions, but the megaminx has about 10^68 positions. But yeah, it does *look* scrambled, and so few people are good at megaminx anyway that it almost doesn't matter

Isn't whether or not you need to solve for parity dependent on your method to solve it? I would think especially that one's method of getting to square would have some impact on it.

But maybe if you are always optimal getting to square, parity isn't affected?

I'm just curious about it. Probably I'm just being stupid bringing this up and the answer is obvious; I've been pretty stupid about things all day.

Its actually quite comparable to 4x4. Parity can be changed during the scramble, and also during cubeshape solving, similar to how the number of slice turns performed during scrambling and center-solving affects the parity outcome on 4x4. While its true that the alg you use for solving cubeshape can change the parity, the length of the alg doesn't necessarily have any bearing, especially since there are multiple optimal algs for a lot of shapes. This is discussed a lot more in depth in this thread.

01:52.26, 01:50.01, 01:50.94, 01:50.61, 01:54.65

Pretty consistent!

Good, I just thought I was being particularly fortunate.

I had a quick talk with Joey at UK Masters as to whether the WCA scrambler was random moves or random state. With very little knowledge about the subject, why is a random state scrambler not used? I was under the impression that an optimal solver existed and as any permutation can be reached, random state should be easy to generate. Or maybe I'm just being naive

Edit: may as well state an accomplishment:
