Recurring PLL within a time

[hawkmp4]

You all DO realise that, though certain PLLs have a higher probability of occurring than others, this never changes?

It has to do with the position of the moon and what you had for dinner the night before.

Seriouly though, this topic and some of the claims here are just ridiculous. Please post a real analysis before saying things like 20 PLL skips in a row.
And learn some basic statistics and combine that with learning the probabilities of each PLL

I hope you're joking. Cubes=Life has these occurrences all the time

Yeah, ZB_FTW!!! (pun intended)

I have noticed I frequently get the perm where you need to cycle 3 edges and 3 corners,
what is that perm called?

G-perms.

I usually have the same PLLs in a row of a few solves when I scramble with no alg (in the tram or outside or something). I even notice I apply a similar pattern to my scrambles, there also was a thread about this.

 

[Zane_C]

I should practice the G-perms more, I sometimes get confused cause they are all inverses of each other.

 

[Cride5]

Just to clarify, here are the approximate percentage probabilities, and exact values for the probability of occurrence of each permutation.

G 22.2% - 2/9 (1/18 for each)
U 11.1% - 1/9 (1/18 for each)
A 11.1% - 1/9 (1/18 for each)
R 11.1% - 1/9 (1/18 for each)
J 11.1% - 1/9 (1/18 for each)
F 5.6% - 1/18
T 5.6% - 1/18
V 5.6% - 1/18
Y 5.6% - 1/18
Z 2.8% - 1/36
E 2.8% - 1/36
N 2.8% - 1/36 (1/72 for each)
H 1.4% - 1/72

These exact probabilities will only occur in reality if a random-state scrambler is used. If scrambling by hand or by applying a random sequence of turns then they may vary, but I shouldn't imagine it would vary by much.

NOTE: Scramblers which apply 25 random moves (such as those on cubetimer.com or qqtimer) aren't random-state, and result in a bias towards states which are closer to solution. As far as I know there are no javascript implementations of a 3x3 random-state scrambler at the moment..

I think what iSpinz pointed out is true. Any PLLs which are notable for some reason (ie, you don't know them, or have issue with them) are more likely to be noticed and so may appear to occur more frequently.

Aaah, sorry Arnaud, I was making a joke.
I actually do have whole averages in which I skip PLL for the whole average.
The only time I have to do PLL in when I do the wrong case, or I forget the case.

I have a video~

Random distributions are NOT the same as uniform distributions.

Cride5, you forgot one perm that occurs 1/72 of the time and is really nice.

Lol, yea the 'solved' perm. Pity it doesn't happen as much as G-perm :rolleyes:

Wow i didn't expect this many replies to this topic.

And learn some basic statistics and combine that with learning the probabilities of each PLL

I especially didn't expect some one like AvGalen to reply but any way to clear this up. Yes I've know about the probabilty since before I even started learning PLL.The point is though why is it always that one PLL within a week ,2 weeks,or even a month.And not more G permutations for example(I haven't gotten one of those in almost 3 weeks).

Frankly, I don't believe you.
Write down the number of each permutation you get for a week. Post em here.

 

[deadalnix]

Totally, like, sometimes I get 4-5 PLL skips in a row.
Other times I get like, 20 PLL skips in a row.

yeah, the probability is just 1/14016833953562607293918185758734155776 .

You should play to some lotery.

With cube explorer generated scrambles.

You know that was a joke right?

Now I know

 

[OregonTrail]

I'm just a beginner (using an LBL method), but I get the feeling that when doing the cross or any intuitive step, one's subconscious mind can influence the permutations that show up later on.

I doubt that somehow. You can force skips if you can see and predict them, but I don't think its got anything to do with the subconcious.
