Your Average Cross Efficiency

[guitardude7241]

the optimal move count is 5 or so, i'm not sure(but i am sure someone will correct me).

The optimal move count I think is no more then 8.

1) 8
2) 9
3) 7
4) 6
5) 7
6) 9
7) 7
8) 6
9) 8
10) 7
11) 7
12) 6

Average = 7.25 moves

Lars put together a cross study here if you're interested in more information on cross statistics.

Well that is a computer doing the solving, I think he's interested in how people actually fare.

What's the difference between an X-cross and a cross?

 

[Kian]

Lars put together a cross study here if you're interested in more information on cross statistics.

Well that is a computer doing the solving, I think he's interested in how people actually fare.

Of course, I was merely providing him with more information about the subject he was interested in. Also, he asked for someone to correct him about optimal solving, so I figured that information would have some value for him.

Anywho, my mean was 6.4 but I didn't save the solutions. I could probably recreate them, though, if need be.

@ZaneC An X-cross is short for "Extended Cross". This means you solve the cross and one pair simultaneously.

 

[cmhardw]

What's the difference between an X-cross and a cross?

X-cross solves the cross and also the 1st corner edge pair together, rather than in two separate steps.

I actually take a more liberal definition of what X-cross is. I wrote a post about it a long time ago. Let me see if I can find it...

Ok here it is:

I consider Xcross to be either:
1) seeing the direct solve to the Xcross during inspection
2) seeing the solve for the 2x2x2 and one other cross edge during inspection, with intention to locate and place the 4th cross edge during the solving phase.
3) seeing the solve for the 2x2x2 during inspection while making sure that the solution for the 2x2x2 puts the other 2 cross edges in a "good" position. A good position means easy to solve in relatively few moves.
4) Seeing the solve for the cross during inspection that either builds or preserves a c/e pair. For these solves you usually know how to place the pair during inspection as well.
5) Seeing the solve for the cross and one corner during inspection, with intention to locate and place the F2L edge during the solving phase using keyhole.
6) Seeing the solve for the cross and one F2L edge during inspection, with intention to locate and place the corresponding corner during the solving phase using keyhole.

X-cross solves the cross and also the 1st corner edge pair together, rather than in two separate steps.

Thanks, that seems complicated.

Quite surprised with this. I was expecting something more than 7.

hmm do you guys know a website/program that gives scrambles and shows you the cross solutions? i heard badmephisto mentrion about it once but i think the link isn't working.. thanks
